asmith Posted June 21, 2009 Share Posted June 21, 2009 Hi, In a script, I will give a file to a converter : e.g <?php exec('converter.exe file.ext'); ?> converter will convert the file in some time. (depends on the file size) When the converter is done, It will save a file to the same locaton as file.ext2 With the same script I need to file_get_content('file.ext2'); If I put that code after the exec line, It will probably give me the file not found error if it is in the middle of the conversion and no one has been generated yet. What is the fastest way to ask for the file EXACTLY after the conversion is done? I thought about putting a loop like <?php while (!file_exists('file.ext2')) continue; // If php is here, then file is generated file_get_content('file.ext2'); ?> Is it a good way? Any better and faster way? Thanks Link to comment https://forums.phpfreaks.com/topic/163109-solved-how-to-find-out-that-the-conversion-is-done-and-ready/ Share on other sites More sharing options...

Your script will wait at the call to exec() before continuing.

trq Posted June 21, 2009 Share Posted June 21, 2009 Your script can't move on until your function call returns a result.

Daniel0 Posted June 21, 2009 Share Posted June 21, 2009 What you can do is to fork the process, but it will only work on Linux/Mac.
