This modest extension adds the functions 'strerror' and 'strsignal' for use with 'exec' and friends and pcntl functions.
v 1.0.1 suppresses a warning about int pointer conversion
<?php exec("ls /root", $output, $error); if ($error) die("OS Error: $error = " . strerror($error)); echo nl2br(implode('', $output)); ?>
OS Error: 1 = Operation not permitted
Many packages override the default error code meanings.
This is not a bug per se, but the end user of this function will need to provide their own facility to override the default error messages for those codes that are over-ridden.
This extension probably should be folded into main/exec.c at some point, after sufficient testing, and if it is popular enough.
Tested on: FreeBSD 5.3 and 4.11, and RedHat 7
