Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. I've added preg_last_error() to the "See Also" section of the following functions: preg_match, preg_match_all, preg_replace, preg_replace_all, and preg_split. Is that sufficient, or is there anything else that you were wanting?

Surely it must be documented. ------------------------------------------------------------------------ [2010-06-08 14:30:37] felipe@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php ------------------------------------------------------------------------ [2010-05-20 16:04:05] dscotese at litmocracy dot com Sorry I was not clear in my last post. This is a documentation problem. No test script is necessary. Simply add a reference to preg_last_error to the preg_replacement documentation. However, when you call preg_replace with an array of patterns and replacements, it can fail even though calling it with the corresponding pairs of pattern/replacement one at a time does not fail. I'd consider that a weakness, but not a bug. If it's possible, preg_replace could be rewritten so that when it takes arrays and fails in a way that doesn't indicate any bad patterns, it tries to do the replacements one at a time. But that is not what this bug report is about. I leave it to you to decide if preg_replace should be made more robust in that way. ------------------------------------------------------------------------ [2010-05-20 14:31:28] mike@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
