note 109938 added to function.preg-replace-callback

The easiest way to pass more than one parameters to the callback function is with the 'use' keyword. [This is better than using global, because it works even when we are already inside a function.] In this example, the callback function is an anonymous function, which takes one argument, $match, supplied by preg_replace_callback(). The extra "use ($ten)" puts the $ten variable into scope for the function. $string = "Some numbers: one: 1; two: 2; three: 3 end"; $ten = 10; $newstring = preg_replace_callback( '/(\d+)/', function($match) use ($ten) { return (($match[0] + $ten)); }, $string ); echo $newstring; #prints "Some numbers: one: 11; two: 12; three: 13 end"; ---- Server IP: 94.76.225.145 Probable Submitter: 87.194.171.29 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace-callback.php Edit -- https://master.php.net/note/edit/109938 Del: integrated -- https://master.php.net/note/delete/109938/integrated Del: useless -- https://master.php.net/note/delete/109938/useless Del: bad code -- https://master.php.net/note/delete/109938/bad+code Del: spam -- https://master.php.net/note/delete/109938/spam Del: non-english -- https://master.php.net/note/delete/109938/non-english Del: in docs -- https://master.php.net/note/delete/109938/in+docs Del: other reasons-- https://master.php.net/note/delete/109938 Reject -- https://master.php.net/note/reject/109938 Search -- https://master.php.net/manage/user-notes.php
