PHP function array_walk_recursive
This function is similar to the array_walk function, however array_walk_recursive() can walk with a deeper array. This function runs each array element (keys and values) to the user-defined function, and it returns TRUE or FALSE according to the statement defined within the user-defined function.
Syntax array_walk_recursive
- array: array input
- callback: user-defined function to process the array key and value.
- para (optional): user-defined parameter to be included with the callback function.
array_walk_recursive(array, callback, para);
Note
function callback($val, $key, $para) {
statement
}
Example 1
<?php
function score_u($score, $name) {
echo "{$name} scores {$score}<br/>";
}
$score = array(
'Taylor' => 32,
'Lucas' => 12,
'Makayla' => 42,
'Jennifer' => 12,
'Group Lucas' => array('John' => 30, 'Mark' => 31)
);
array_walk_recursive($score, "score_u");
?>
Output
Taylor scores 32 Lucas scores 12 Makayla scores 42 Jennifer scores 12 John scores 30 Mark scores 31
