note 84240 added to language.types.string

In response to sassospicco: When you set the character to null it also changed the type to null, other users should note that if you want to set characters to null in this fashion that you should use an escape sequence to keep the variable as type string. Here's sassospicco's altered code with the null character (instead of NULL type), all output is as desired. <?php $a = 'AB'; echo strlen($a)."\n"; // 2 // Ok so far $a[1] = "\x00"; echo strlen($a)."\n"; // 2 // The second character still exists... var_dump($a); // string(2) "A" echo ord($a[1]); //ASCII value: 0 ?> ---- Server IP: 117.104.160.194 Probable Submitter: 124.186.94.4 ---- Manual Page -- http://www.php.net/manual/en/language.types.string.php Edit -- https://master.php.net/note/edit/84240 Del: integrated -- https://master.php.net/note/delete/84240/integrated Del: useless -- https://master.php.net/note/delete/84240/useless Del: bad code -- https://master.php.net/note/delete/84240/bad+code Del: spam -- https://master.php.net/note/delete/84240/spam Del: non-english -- https://master.php.net/note/delete/84240/non-english Del: in docs -- https://master.php.net/note/delete/84240/in+docs Del: other reasons-- https://master.php.net/note/delete/84240 Reject -- https://master.php.net/note/reject/84240 Search -- https://master.php.net/manage/user-notes.php
