note 130663 added to function.in-array

It's worth the notice that in_array is case-sensitive. Apart from the very first option of make all lowercase or uppercase, and then compare, I found this elegant solution: <?php function in_arrayi(float|int|string $needle, array $haystack):bool { return (bool)array_uintersect([$needle],$haystack,strcasecmp(...)); } $needle = "abc"; $haystack = ["Abc","deF","gHi"]; $result = in_arrayi($needle,$haystack); var_dump($result); ?> ---- Server IP: 206.189.2.9 Probable Submitter: 2800:a4:c0de:2c00:bc6f:73bf:ab79:1ace ---- Manual Page -- https://php.net/manual/en/function.in-array.php Edit -- https://main.php.net/note/edit/130663 Del: integrated -- https://main.php.net/note/delete/130663/integrated Del: useless -- https://main.php.net/note/delete/130663/useless Del: bad code -- https://main.php.net/note/delete/130663/bad+code Del: spam -- https://main.php.net/note/delete/130663/spam Del: non-english -- https://main.php.net/note/delete/130663/non-english Del: in docs -- https://main.php.net/note/delete/130663/in+docs Del: other reasons-- https://main.php.net/note/delete/130663 Reject -- https://main.php.net/note/reject/130663 Search -- https://main.php.net/manage/user-notes.php
