note 66795 added to function.system

You probably want to check your system calls for errors. The convention is to return 0 for "no error" which is the same as FALSE which can be confusing. You need to do something like: <?php $cmd = "/usr/bin/pngtopnm $png_file > $pnm_file"; system($cmd,$return_value); ($return_value == 0) or die("returned an error: $cmd"); ?> ---- Server IP: 216.194.113.175 Probable Submitter: 66.92.77.160 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.system.php Edit -- http://master.php.net/note/edit/66795 Del: integrated -- http://master.php.net/note/delete/66795/integrated Del: useless -- http://master.php.net/note/delete/66795/useless Del: bad code -- http://master.php.net/note/delete/66795/bad+code Del: spam -- http://master.php.net/note/delete/66795/spam Del: non-english -- http://master.php.net/note/delete/66795/non-english Del: in docs -- http://master.php.net/note/delete/66795/in+docs Del: other reasons-- http://master.php.net/note/delete/66795 Reject -- http://master.php.net/note/reject/66795 Search -- http://master.php.net/manage/user-notes.php
