• Set ENV PATH of php and ffmpeg to use it inside PHP scripts with CLI like shell_exec()

  24 février 2015, par user3774451

  I would like to execute commands in a php script like this :

  <?php
  
  shell_exec(php myfile.php)

  or

  <?php
  
  shell_exec(ffmpeg -i ...)

  My problem, i think is that php and ffmpeg path are not properly configured in my apache environment because when i execute this :

  <?php
  
  var_dump(shell_exec("which php"));
  
  var_dump(shell_exec("which ffmpeg"));

  I get this answer :

  string '/usr/bin/php' (length=13)
  
  null

  But in the terminal when i type :

  which php
  
  which ffmpeg

  I get this answer :

  /usr/local/opt/php55/bin/php
  
  /usr/local/bin/ffmpeg

  So how can i set properly the php and ffmpeg environment path without always retype the complete path ?

  I am under Mac OsX 10.10 and i installed php and ffmpeg whith brew.
