Combine two arrays into a single array:
| <?php $a1=array(“a”=>“red”,“b”=>“green”); $a2=array(“c”=>“blue”,“b”=>“yellow”); print_r(array_merge_recursive($a1,$a2)); ?> |
The array_merge_recursive() function combines one or more arrays into a single array.
Unlike array_merge(), which overrides values for duplicate keys, array_merge_recursive() merges values into an array if the keys are the same.
Note: When only one array is passed to array_merge_recursive(), it behaves the same as array_merge().
