本文实例讲述了PHP递归调用数组值并用其执行指定函数的方法,分享给大家供大家参考,具体分析如下:
以下为wordpress原代码,为了偷懒,简单修改一下以适用其它函数。
- /**
- * 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 $value;
- }
- <?php
- function function_deep($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));
- // 输出结果
- // 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)
- ?>
