From: Operating system: Linux PHP version: Irrelevant Package: Filesystem function related Bug Type: Feature/Change Request Bug description:RFE: can we have `which`
Description:
------------
It would be nice if PHP had a builtin "which" command.
For example, which("ffmpeg") would allow the user to check whether ffmpeg
was installed, prior to calling it with exec().
Test script:
---------------
which("ffmpeg") should return eg:
/usr/bin/ffmpeg
if the command exists, and is in the £PATH for exec(), or
false
if it doesn't exist.
