Edit report at https://bugs.php.net/bug.php?id=72866&edit=1 ID: 72866 Comment by: imbibinebe at gmail dot com Reported by: imbibinebe at gmail dot com Summary: in_array confusing strings and integers Status: Open Type: Feature/Change Request Package: *General Issues Operating System: debian PHP Version: 5.6Git-2016-08-17 (Git) Block user comment: N Private report: N New Comment: And at least, the final result resulting of my test is: // 'string' == 0 -> bool(true) should that be allright ? :) Previous Comments: ------------------------------------------------------------------------ [2016-08-17 14:27:24] ryosuke_i_628 at yahoo dot co dot jp Sorry, I was missing your important sentence: > 'Expected result' should be obtained without using the third parameter of in_array BTW, I think this behavior seems to be a little odd, too... Probably you know the related issue; array_unique() was broken at PHP 5.2.9 due to use SORT_REGULAR by default, which feature is reverted at PHP 5.2.10 to use SORT_STRING. ------------------------------------------------------------------------ [2016-08-17 14:21:19] ryosuke_i_628 at yahoo dot co dot jp This is VERY WELL-KNOWN feature of PHP, not a bug. Just pass true as 3rd argument. (default is false) Read documentation: http://php.net/manual/en/function.in-array.php <?php $needle = 's'; $elements = [1]; var_dump(in_array($needle, $elements, false)); // 's' == 1 -> bool(true) var_dump(in_array($needle, $elements, true)); // 's' === 1 -> bool(false) ------------------------------------------------------------------------ [2016-08-17 14:02:53] imbibinebe at gmail dot com Description: ------------ using PHP Version 5.6.14-0+deb8u1 on a debian operating system, here is what I get with the following testing script. I think that 'Expected result' should be obtained without using the third parameter of in_array ([, bool $strict = FALSE ]) otherwise it is very confusing. Test script: --------------- echo 'test1:'.(in_array('string',[0,1])?'true':'false'); echo 'test2:'.(in_array('string',[1])?'true':'false'); echo 'test3:'.(in_array('string',[0])?'true':'false'); Expected result: ---------------- test1:false test2:false test3:false Actual result: -------------- test1:true test2:false test3:true ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72866&edit=1
