public static function NestedArray::mergeDeep in Plug 7
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.
