How to recursively call an array value in PHP and use it to execute a specified function_PHP Tutorial

PHP recursively calls the array value and uses it to execute the specified function

The following is the original wordpress code. To be lazy, simply modify it to apply to 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:

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) ?>
