Edit report at https://bugs.php.net/bug.php?id=60602&edit=1 ID: 60602 Updated by: datibbaw@php.net Reported by: me at ktamura dot com Summary: $env can be destructively changed. Status: Open Type: Documentation Problem Package: Documentation problem Operating System: OSX 10.6.8 PHP Version: 5.4SVN-2011-12-23 (SVN) Block user comment: N Private report: N New Comment: The behaviour is accompanied by a notice as well: > PHP Notice: Array to string conversion in file on line number The notice comes from here: http://lxr.php.net/xref/PHP_5_4/ext/standard/proc_open.c#490 Any element in $_SERVER that's not a string will get converted. This should be reflected in the documentation. Previous Comments: ------------------------------------------------------------------------ [2012-02-25 20:36:53] virtual dot greg at gmail dot com This does manifest in PHP 5.3.8 on OS X 10.6.8 as well. A question to the OP: the documentation says to pass NULL to use the same environment as the current PHP process. If ['argv'] is a string it is unaffected. Only if the element is an array does this modification occur.

We should either document so or change the behavior of the function so that $env's values are not changed as a result of invoking proc_open. Test script: --------------- <?php print_r($_SERVER['argv']); $pipes = array(); proc_open('/bin/echo', array(), $pipes, null, $_SERVER); print_r($_SERVER['argv']); Expected result: ---------------- Array ( [0] => ../futz/a.php ) Array ( [0] => ../futz/a.php ) Actual result: -------------- Array ( [0] => ../futz/a.php ) Array ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60602&edit=1
