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 strpos doesn\'t return true on success but the position ------------------------------------------------------------------------ [2005-11-01 00:12:28] john dot clements at publicinfo dot net Description: ------------ This is a problem with === true and !== true whether used with strpos or with array_search and presumably with other functions. This also fails under PHP 4.3.10 on FreeBSD 4.8-STABLE, but that is a hosted server and I can't upgrade it to test. I have done further testing and found that checking for === false or !== false is OK: === false works when statement is true === false works when statement is false === true doesn't work when statement is true === true works when statement is false !== true doesn't work when statement is true !== true works when statement is false !== false works when statement is true !== false works when statement is false Pls get in touch if you would like the code to show that. Reproduce code: --------------- <?php if (strpos("hey","h") === true) print "1. worked \n"; else print "1. didn't work\n"; if (strpos("hey","h") !== false) print "2. worked \n"; else print "2. didn't work\n"; ?> Expected result: ---------------- 1. worked 2. worked Actual result: -------------- 1. didn't work 2. worked ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35041&edit=1
