PHP array_merge_recursive() Functions
Example
Merge two arrays into one array:
<?php
$a1=array("a"=>"red","b"=>"green");
$a2=array("c"=>"blue","b"=>"yellow");
print_r(array_merge_recursive($a1,$a2));
?>
Definition and Usage
The array_merge_recursive() function merges one or more arrays into one array.
This function is similar to array_merge() The difference between the functions lies in the handling of the same key names for two or more array elements. array_merge_recursive() does not perform key name overlay, but recursively combines multiple values with the same key name into an array.
Note:If you only input an array into the array_merge_recursive() function, the result is the same as array_merge(), and the function will return a new array with integer keys, re-indexing starting from 0.
