Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient.

This is not reflected in the documentation. Test script: --------------- <?php var_dump(strtr('foo', array('' => 'nothing'))); Expected result: ---------------- Unsure, is the empty string ever really "found" in a string? Actual result: -------------- bool(false) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51908&edit=1
