Description: ------------ The var_export distributed with compat 1.4.1 is so broken it's a joke: - no support for nested arrays above 2 levels - usage of str_replace with array alements is not compatible below php 4.0.5 - breaks hard on NULLS, BOOLEANS, FLOATS, RESOURCES Attached below is a mostly rewritten implementation, which has been hastily tested with php 4.04pl1. Hope it helps...

I think I got it wrong about nested arrays not being supported, but when running the following code snippet I get quite a few php warnings (php 4.0.4pl1+pear var_export) and different results from php 4.4.0 with built_in var_export <pre> <?php include('var_export.php'); var_export(true); var_export(false); var_export(null); $fp = fopen(getcwd().'/var_export.php', 'r'); var_export($fp); fclose($fp); var_export(array(1, array(2, array(3,4), array(5,array(6, array(7)))))); ?> </pre> PS: BTW: 6 days is quite a short notice for suspending a bug for missing feedback. 1 to 3 months is more likely a meaningful timespan. Or do the PEAR package maintainers expect to release a new version every month???

Close, but no cigar :) 1 - For object variables, members of type array are not properly indented. You should probably use for object members the same explode, indent, implode code used for array values. 2 - But there is a small catch in the "explode, indent, implode" method: try running var_export(array(array("a\nb"))) to see a couple of extra chars added to the string dump. This is (imho) not only a cosmetic bug, but a data misrepresentation bug, ie a little bit more important. Afaict the only solution would be to adopt the code I proposed, with the extra 3rd param added to represent the current indentation level, or use a global var for that and have the code not be reentrant anymore.

PS: code runs fine on PHP 441
