Previous Comments: ------------------------------------------------------------------------ [2011-04-20 16:02:54] dtajchreber@php.net Added a blurb that in_array uses loose comparison unless $strict is set and the default value for the strict parameter is false. ------------------------------------------------------------------------ [2011-04-20 16:00:07] dtajchreber@php.net Automatic comment from SVN on behalf of dtajchreber Revision: http://svn.php.net/viewvc/?view=revision&revision=310394 Log: Fixing mistake made with last commit (#54574) ------------------------------------------------------------------------ [2011-04-20 15:58:30] dtajchreber@php.net Automatic comment from SVN on behalf of dtajchreber Revision: http://svn.php.net/viewvc/?view=revision&revision=310392 Log: Fixed #54574 - clarified that in_array uses loose comparison by default ------------------------------------------------------------------------ [2011-04-20 06:21:33] ss23 at ss23 dot geek dot nz Description: ------------ Consider: $safeColors = array(1,2,3,4,5,6,7,8,9,0,'a','b','c','d','e','f'); var_dump(in_array('T', $safeColors)); People not paying attention would assume "false", however, because T is compared with integers, it seems to be cast to 0, therefore, outputting true. A "solution" would be a warning on the in_array page, as this isn't a problem with the function, just something that confuses users who aren't expecting it. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54574&edit=1
