PHP recursively calls the array value and uses it to execute the specified function. recursive array _ PHP Tutorial

PHP recursively calls the array value and uses it to execute the specified function, recursively returning the array. PHP recursively calls the array value and uses it to execute the specified function. This document describes how PHP recursively calls the array value and uses it to execute the specified function. We will share with you how PHP recursively calls the array value and uses it to execute the specified function. recursive array

This example describes how PHP recursively calls an array value and uses it to execute a specified function. Share it with you for your reference. The specific analysis is as follows:

The following is the original wordpress code. to be lazy, modify it to apply other functions.

/*** Navigates through an array and removes slashes from the values.** If an array is passed, the array_map() function causes a callback to pass the* value back to the function. The slashes from this value will removed.** @since 2.0.0** @param mixed $value The value to be stripped.* @return mixed Stripped value.*/function stripslashes_deep($value) { if ( is_array($value) ) {  $value = array_map('stripslashes_deep', $value); } elseif ( is_object($value) ) {  $vars = get_object_vars( $value );  foreach ($vars as $key=>$data) {   $value->{$key} = stripslashes_deep( $data );  } } elseif ( is_string( $value ) ) {  $value = stripslashes($value); } return $value;}

The code is as follows:

<? Php function function_deep ($ function, $ value) {try {if (! Function_exists ($ function) {$ error = '"'. $ function. '"is undefined'; throw new Exception ($ error) ;}} catch (Exception $ e) {echo 'caught exception: ', $ e-> getMessage (), "\ n"; die () ;}if (is_array ($ value) {$ fun = Array (); for ($ I = 1; $ I <= count ($ value); $ I ++) {$ fun [] = $ function;} $ value = array_map ("function_deep", $ fun, $ value);} elseif (is_object ($ value) {$ vars = get_object_vars ($ value ); Foreach ($ vars as $ key => $ data) {$ value-> {$ key} = function_deep ($ function, $ data );}} elseif (is_string ($ value) {$ value = call_user_func ($ function, $ value) ;}return $ value ;}$ arr = array ("I'm bean ", "I'm bean", array ("I'm bean", "I'm bean"); var_dump (function_deep ("addslashes", $ arr )); // output result // array (size = 3) // 0 => string 'I \'m Bean' (length = 9) // 1 => string 'I \'m Bean' (length = 9) // 2 =>/ /Array (size = 2) // 0 => string 'I \'m Bean' (length = 9) // 1 => string 'I \'m Bean' (length = 9)?>
