note 77544 added to function.is-string

re: php dot net at oui dot jp <?php $a = array('0' => 'zero'); // '0' // is different from $b = '0'; // '0' ?> Because when you use array, it will automatically change the key to integer if it could. So, it output: >php -r "print var_dump(array_keys(array('0' => ' zero', '1' => 'one')));" array(2) { [0]=> int(0) [1]=> int(1) } They are int type, not string. ---- Server IP: 123.253.132.202 Probable Submitter: 127.0.0.1 (proxied: 61.171.156.82) ---- Manual Page -- http://www.php.net/manual/en/function.is-string.php Edit -- https://master.php.net/note/edit/77544 Del: integrated -- https://master.php.net/note/delete/77544/integrated Del: useless -- https://master.php.net/note/delete/77544/useless Del: bad code -- https://master.php.net/note/delete/77544/bad+code Del: spam -- https://master.php.net/note/delete/77544/spam Del: non-english -- https://master.php.net/note/delete/77544/non-english Del: in docs -- https://master.php.net/note/delete/77544/in+docs Del: other reasons-- https://master.php.net/note/delete/77544 Reject -- https://master.php.net/note/reject/77544 Search -- https://master.php.net/manage/user-notes.php
