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 str_replace() operates on strings and returns array of strings. of course, NULL, false and others get converted to "" even before str_replace() begin to work with them. Previous Comments: ------------------------------------------------------------------------ [2005-06-30 23:55:16] tony at marston-home dot demon dot co dot uk Description: ------------ When I use str_replace on an associative array to replace '<br>' with "\n" I find that values that were null have been replaced with empty strings. This affects subsequent processing as an empty string is not the same as null. Reproduce code: --------------- $pattern[] = "<br>"; $pattern[] = "<br/>"; $pattern[] = "<br />"; $replacement = "\n"; $array = array('field1' => '<br>', 'field2' => '', 'field3' => null) $array = str_replace($pattern, $replacement, $array); Expected result: ---------------- Null values should be left as null values, and not replaced with empty strings. Actual result: -------------- Values in the array that were null are being replaced with empty strings. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33530&edit=1
