note 62172 added to function.array-walk-recursive

I decided to add to the previous PHP 4 compatible version of array_walk_recursive() so that it would work within a class and as a standalone function. Both instances are handled by the following function which I modified from omega13a at sbcglobal dot net. The following example is for usage within a class. To use as a standalone function take it out of the class and rename it. (Example: array_walk_recursive_2) <?php class A_Class { function array_walk_recursive(&$input, $funcname, $userdata = '') { if(!function_exists('array_walk_recursive')) { if(!is_callable($funcname)) return false; if(!is_array($input)) return false; foreach($input as $key=>$value) { if(is_array($input[$key])) { if(isset($this)) { eval('$this->' . __FUNCTION__ . '($input[$key], $funcname, $userdata);'); } else { if(@get_class($this)) eval(get_class() . '::' . __FUNCTION__ . '($input[$key], $funcname, $userdata);'); else eval(__FUNCTION__ . '($input[$key], $funcname, $userdata);'); } } else { $saved_value = $value; if(is_array($funcname)) { $f = ''; for($a=0; $a<count($funcname); $a++) if(is_object($funcname[$a])) { $f .= get_class($funcname[$a]); } else { if($a > 0) $f .= '::'; $f .= $funcname[$a]; } $f .= '($value, $key' . (!empty($userdata) ? ', $userdata' : '') . ');'; eval($f); } else { if(!empty($userdata)) $funcname($value, $key, $userdata); else $funcname($value, $key); } if($value != $saved_value) $input[$key] = $value; } } return true; } else { array_walk_recursive($input, $funcname, $userdata); } } function kv_addslashes(&$v, $k) { $v = addslashes($v); } } ?> Usage: <?php $arr = array( 'a' => '"Hello World"', 'b' => "'Hello World'", 'c' => "Hello 'Worl\"d", 'd' => array( 'A' => 'H"e"l"l"o" "W"o"r"l"d' ) ); $class = new A_Class(); $class->array_walk_recursive($arr, array(&$class, 'kv_addslashes')); print_r($arr); ?> ---- Server IP: 216.194.113.175 Probable Submitter: 68.194.110.148 ---- Manual Page -- http://www.php.net/manual/en/function.array-walk-recursive.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+62172 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+62172&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+62172&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+62172&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+62172&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+62172&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+62172&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+62172&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+62172&report=yes Search -- http://master.php.net/manage/user-notes.php
