Previous Comments: ------------------------------------------------------------------------ [2006-09-19 15:34:40] ryanhollett at hotmail dot com This was tested on version 4.4.0, 4.4.1, 4.4.4 for Windows. This may be a documentation problem or an issue with the function itself depending on the intended functionality. ------------------------------------------------------------------------ [2006-09-19 15:31:54] ryanhollett at hotmail dot com Description: ------------ From the php documentation for the min function "PHP will evaluate a non-numeric string as 0, but still return the string if it's seen as the numerically lowest value." It seems that this is incorrect. When a non-numeric string and a numeric string are passed in, the numeric string seems to be returned as the the min value. Reproduce code: --------------- <?php echo min("a", "2"); echo "\n"; echo min("2", "a"); echo "\n"; echo min("a", "-2"); echo "\n"; echo min("-2", "a"); ?> Expected result: ---------------- a a -2 -2 Actual result: -------------- 2 2 -2 -2 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38883&edit=1
