8 NestedArray.php public static NestedArray::mergeDeep()

Merges multiple arrays, recursively, and returns the merged array.

This function is similar to PHP's array_merge_recursive() function, but it handles non-array values differently. When merging values that are not both arrays, the latter value replaces the former rather than merging with it.

Example:

$link_options_1 = array('fragment' => 'x', 'attributes' => array('title' => t('X'), 'class' => array('a', 'b')));
$link_options_2 = array('fragment' => 'y', 'attributes' => array('title' => t('Y'), 'class' => array('c', 'd')));

// This results in array('fragment' => array('x', 'y'), 'attributes' => array('title' => array(t('X'), t('Y')), 'class' => array('a', 'b', 'c', 'd'))).
$incorrect = array_merge_recursive($link_options_1, $link_options_2);

// This results in array('fragment' => 'y', 'attributes' => array('title' => t('Y'), 'class' => array('a', 'b', 'c', 'd'))).
$correct = NestedArray::mergeDeep($link_options_1, $link_options_2);

Parameters

array ...: Arrays to merge.

Return value

array The merged array.
