| 标题 | PHP递归调用数组值并用其执行指定函数的方法 |
| 内容 | 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 $value; } 代码如下： <?php function function_deep($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) ?> |
