This function efficiently implements checks for strings beginning or ending with other strings: <?php function str_begins($haystack, $needle) { return 0 === substr_compare($haystack, $needle, 0, strlen($needle)); } function str_ends($haystack, $needle) { return 0 === substr_compare($haystack, $needle, -strlen($needle)); } var_dump(str_begins('http://example.com', 'https://')); ?> Note that these are not multi-byte character set aware. ---- Server IP: 72.52.91.14 Probable Submitter: 107.15.255.60 ---- Manual Page -- http://php.net/manual/en/function.substr-compare.php Edit -- https://master.php.net/note/edit/119982 Del: integrated -- https://master.php.net/note/delete/119982/integrated Del: useless -- https://master.php.net/note/delete/119982/useless Del: bad code -- https://master.php.net/note/delete/119982/bad+code Del: spam -- https://master.php.net/note/delete/119982/spam Del: non-english -- https://master.php.net/note/delete/119982/non-english Del: in docs -- https://master.php.net/note/delete/119982/in+docs Del: other reasons-- https://master.php.net/note/delete/119982 Reject -- https://master.php.net/note/reject/119982 Search -- https://master.php.net/manage/user-notes.php
