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:
1 2 3 4 5 6 7 8 | $link_options_1 = array('fragment' => 'x', 'attributes' => array('title' => t('X'), 'class' => array('a', 'b')));$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
