How to Show result after uploaded file in PHP
23 avril 2022, par i0x4rI have a script that uploads the video to a server, everything is correct but there is a problem, after the upload of the video to the server is completed
it shows all the uploaded files in the (uploads) folder as array !


I only want the result of the file I just uploaded, and it doesn't show me the previous files !
I need ffmpeg to improve video quality


index.php

upload.php


<?php

//upload.php

$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';

if(!empty($_FILES))
{

 $temp_file = $_FILES['file']['tmp_name'];
 $location = $folder_name . $_FILES['file']['name'];
 move_uploaded_file($temp_file, $location);
 $upload = $_FILES['file']['name'];
 $uploadStr = str_replace(" ", "\ ",$upload);
 $locationStr = str_replace(" ","\ ",$location);
 $cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
 echo shell_exec($cmd);
}

if(isset($_POST["name"]))
{
 $filename = $folder_name.$_POST["name"];
 $imagename = $thumb_name.$_POST["name"].$imageext;
 unlink($filename);
 unlink($imagename);
}

$result = array();

$files = scandir('upload');

$output = '<div class="row">';

if(false !== $files)
{
 foreach($files as $file)
 {
 if('.' != $file && '..' != $file)
 {
 $output .= '
 <a href="http://stackoverflow.com/view.php?file=&#x27;.$file.&#x27;" target="_blank"> <img src="http://stackoverflow.com/feeds/tag/thumb/&#x27;.$file.&#x27;.png" class="img-thumbnail" width='246' height='138' /></a>
 <button type="button" class="btn btn-link remove_image">Remove</button>
 ';
 }
 }
}
$output .= '</div>';
echo $output;

?>


EDIT :
I put the example on an Array, I don't want it, I just want it to show the downloaded video I just uploaded as a result.


EDIT 2 :
There are some who say type $location and it displays the downloaded file, but this does not work !!!
I just tried more than once and with several uses, there is no display where the text is empty


This is an example of that


<?php

//upload.php

$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';

if(!empty($_FILES))
{

 $temp_file = $_FILES['file']['tmp_name'];
 $location = $folder_name . $_FILES['file']['name'];
 move_uploaded_file($temp_file, $location);
 $upload = $_FILES['file']['name'];
 $uploadStr = str_replace(" ", "\ ",$upload);
 $locationStr = str_replace(" ","\ ",$location);
 $cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
 echo shell_exec($cmd);
}

if(isset($_POST["name"]))
{
 $filename = $folder_name.$_POST["name"];
 $imagename = $thumb_name.$_POST["name"].$imageext;
 unlink($filename);
 unlink($imagename);
}


$output .= 'Successfly file is "'.$location.'"';
echo $output;

?>


Result : Successfly file is ""
no name file :(


EDIT 3 :


this code upload.php
functions not working


<?php

//upload.php

$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';

if(!empty($_FILES))
{

 $temp_file = $_FILES['file']['tmp_name'];
 $location = $folder_name . $_FILES['file']['name'];
 move_uploaded_file($temp_file, $location);
 $upload = $_FILES['file']['name'];
 $uploadStr = str_replace(" ", "\ ",$upload);
 $locationStr = str_replace(" ","\ ",$location);
 $cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
 echo shell_exec($cmd);
}


echo "The file " . $location . " has been uploaded";
// not working

// not working
echo "<br />";
echo "The file " . $uploadStr . " has been uploaded";

About the developer solution Markus AO


I did the experiment and it is quite good, but dropzone is still missing, because I will upload a large video and the normal upload compresses the video before uploading, here is a picture from my mobile while uploading, but this does not happen with dropzone



I want to implement this in dropzone as well, because this library does not compress the video, but upload it in full size.


Thank you bro.

10 Key Google Analytics Limitations You Should Be Aware Of
9 mai 2022, par ErinGoogle Analytics (GA) is the biggest player in the web analytics space. But is it as “universal” as its brand name suggests ?
Over the years users have pointed out a number of major Google Analytics limitations. Many of these are even more visible in Google Analytics 4.
Introduced in 2020, Google Analytics 4 (GA4) has been sceptically received. As the sunset date of 1st, July 2023 for the current version, Google Universal Analytics (UA), approaches, the dismay grows stronger.
To the point where people are pleading with others to intervene :
Source : Chris Tweten via Twitter Main limitations of Google Analytics
Google Analytics 4 is advertised as a more privacy-centred, comprehensive and “intelligent” web analytics platform.
According to Google, the newest version touts :
- Machine learning at its core provides better segmentation and fast-track access to granular insights
- Privacy-by-design controls, addressing restrictions on cookies and new regulatory demands
- More complete understanding of customer journeys across channels and devices
Some of these claims hold true. Others crumble upon a deeper investigation. Newly advertised Google Analytics capabilities such as ‘custom events’, ‘predictive insights’ and ‘privacy consent mode’ only have marginal improvements.
Complex setup, poor UI and lack of support with migration also leave many other users frustrated with GA4.
Source : Alexander Stoffel via Twitter Let’s unpack all the current (and legacy) limitations of Google Analytics you should account for.
1. No Historical Data Imports
Google rushed users to migrate from Universal Analytics to Google Analytics 4. But they overlooked one important precondition — backwards compatibility.
You have no way to import data from Google Universal Analytics to Google Analytics 4.
Historical records are essential for analysing growth trends and creating benchmarks for new marketing campaigns. Effectively, you are cut short from past insights — and forced to start strategising from scratch.
At present, Google offers two feeble solutions :
- Run data collection in parallel and have separate reporting for GA4 and UA until the latter is shut down. Then your UA records are gone.
- For Ecommerce data, manually duplicate events from UA at a new GA4 property while trying to figure out the new event names and parameters.
Google’s new data collection model is the reason for migration difficulties.
In Google Analytics 4, all analytics hits types — page hits, social hits, app/screen view, etc. — are recorded as events. Respectively, the “‘event’ parameter in GA4 is different from one in Google Universal Analytics as the company explains :
Source : Google This change makes migration tedious — and Google offers little assistance with proper events and custom dimensions set up.
2. Data Collection Limits
If you’ve wrapped your head around new GA4 events, congrats ! You did a great job, but the hassle isn’t over.
You still need to pay attention to new Google Analytics limits on data collection for event parameters and user properties.
Source : Google These apply to :
- Automatically collected events
- Enhanced measurement events
- Recommended events
- Custom events
When it comes to custom events, GA4 also has a limit of 25 custom parameters per event. Even though it seems a lot, it may not be enough for bigger websites.
You can get higher limits by upgrading to Google Analytics 360, but the costs are steep.
3. Limited GDPR Compliance
Google Analytics has a complex history with European GDPR compliance.
A 2020 ruling by the Court of Justice of the European Union (CJEU) invalidated the Privacy Shield framework Google leaned upon. This framework allowed the company to regulate EU-US data transfers of sensitive user data.
But after this loophole was closed, Google faced a heavy series of privacy-related fines :
- French data protection authority, CNIL, ruled that “the transfers to the US of personal data collected through Google Analytics are illegal” — and proceeded to fine Google for a record-setting €150 million at the beginning of 2022.
- Austrian regulators also deemed Google in breach of GDPR requirements and also branded the analytics as illegal.
Other EU-member states might soon proceed with similar rulings. These, in turn, can directly affect Google Analytics users, whose businesses could face brand damage and regulatory fines for non-compliance. In fact, companies cannot select where the collected analytics data will be stored — on European servers or abroad — nor can they obtain this information from Google.
Getting a web analytics platform that allows you to keep data on your own servers or select specific Cloud locations is a great alternative.
Google also has been lax with its cookie consent policy and doesn’t properly inform consumers about data collection, storage or subsequent usage. Google Analytics 4 addresses this issue to an extent.
By default, GA4 relies on first-party cookies, instead of third-party ones — which is a step forward. But the user privacy controls are hard to configure without losing most of the GA4 functionality. Implementing user consent mode to different types of data collection also requires a heavy setup.
4. Strong Reliance on Sampled Data
To compensate for ditching third-party cookies, GA4 more heavily leans on sampled data and machine learning to fill the gaps in reporting.
In GA4 sampling automatically applies when you :
- Perform advanced analysis such as cohort analysis, exploration, segment overlap or funnel analysis with not enough data
- Have over 10,000,000 data rows and generate any type of non-default report
Google also notes that data sampling can occur at lower thresholds when you are trying to get granular insights. If there’s not enough data or because Google thinks it’s too complex to retrieve.
In their words :
Source : Google Data sampling adds “guesswork” to your reports, meaning you can’t be 100% sure of data accuracy. The divergence from actual data depends on the size and quality of sampled data. Again, this isn’t something you can control.
Unlike Google Analytics 4, Matomo applies no data sampling. Your reports are always accurate and fully representative of actual user behaviours.
5. No Proper Data Anonymization
Data anonymization allows you to collect basic analytics about users — visits, clicks, page views — but without personally identifiable information (or PII) such as geo-location, assigns tracking ID or other cookie-based data.
This reduced your ability to :
- Remarket
- Identify repeating visitors
- Do advanced conversion attribution
But you still get basic data from users who ignored or declined consent to data collection.
By default, Google Analytics 4 anonymizes all user IP addresses — an upgrade from UA. However, it still assigned a unique user ID to each user. These count as personal data under GDPR.
For comparison, Matomo provides more advanced privacy controls. You can anonymize :
- Previously tracked raw data
- Visitor IP addresses
- Geo-location information
- User IDs
This can ensure compliance, especially if you operate in a sensitive industry — and delight privacy-mindful users !
6. No Roll-Up Reporting
Getting a bird’s-eye view of all your data is helpful when you need hotkey access to main sites — global traffic volume, user count or percentage of returning visitors.
With Roll-Up Reporting, you can see global-performance metrics for multiple localised properties (.co.nz, .co.uk, .com, etc,) in one screen. Then zoom in on specific localised sites when you need to.
7. Report Processing Latency
The average data processing latency is 24-48 hours with Google Analytics.
Accounts with over 200,000 daily sessions get data refreshes only once a day. So you won’t be seeing the latest data on core metrics. This can be a bummer during one-day promo events like Black Friday or Cyber Monday when real-time information can prove to be game-changing !
Matomo processes data with lower latency even for high-traffic websites. Currently, we have 6-24 hour latency for cloud deployments. On-premises web analytics can be refreshed even faster — within an hour or instantly, depending on the traffic volumes.
8. No Native Conversion Optimisation Features
Google Analytics users have to use third-party tools to get deeper insights like how people are interacting with your webpage or call-to-action.
You can use the free Google Optimize tool, but it comes with limits :
- No segmentation is available
- Only 10 simultaneous running experiments allowed
There isn’t a native integration between Google Optimize and Google Analytics 4. Instead, you have to manually link an Optimize Container to an analytics account. Also, you can’t select experiment dimensions in Google Analytics reports.
What’s more, Google Optimize is a basic CRO tool, best suited for split testing (A/B testing) of copy, visuals, URLs and page layouts. If you want to get more advanced data, you need to pay for extra tools.
Matomo comes with a native set of built-in conversion optimization features :
- Heatmaps
- User session recording
- Sales funnel analysis
- A/B testing
- Form submission analytics
A/B test hypothesis testing on Matomo 9. Deprecated Annotations
Annotations come in handy when you need to provide extra context to other team members. For example, point out unusual traffic spikes or highlight a leak in the sales funnel.
This feature was available in Universal Analytics but is now gone in Google Analytics 4. But you can still quickly capture, comment and share knowledge with your team in Matomo.
You can add annotations to any graph that shows statistics over time including visitor reports, funnel analysis charts or running A/B tests.
10. No White Label Option
This might be a minor limitation of Google Analytics, but a tangible one for agency owners.
Offering an on-brand, embedded web analytics platform can elevate your customer experience. But white label analytics were never a thing with Google Analytics, unlike Matomo.
Wrap Up
Google set a high bar for web analytics. But Google Analytics inherent limitations around privacy, reporting and deployment options prompt more users to consider Google Analytics alternatives, like Matomo.
With Matomo, you can easily migrate your historical data records and store customer data locally or in a designated cloud location. We operate by a 100% unsampled data principle and provide an array of privacy controls for advanced compliance.
