PHP array_merge() Function Usage and Example

PHP Array Function Manual

The PHP array_merge() function merges one or more arrays into one array.

Syntax

array array_merge( array $array1　, array $array2　, array $array3...]]);

Definition and Usage

　The array_merge() function merges one or more arrays by combining their elements, appending the values of one array to the end of the previous array. Returns the resulting array.
If there are duplicate string key names in the input arrays, the value after the key name will overwrite the previous value. However, if the array contains numeric key names, the value after will not overwrite the original value, but will be appended to the end.
If only one array is given and the array is numeric indexed, the keys will be reindexed continuously.

Parameter

Return Value

It returns the resulting array.

　　　print_r(array_merge($input,$input1));
?>

Output Result:

Array
(
　　　　[a] => Cat
　　　　[b] => Cat
　　　　[c] => Dog
　　　　[d] => Cow
　　　　[e] => elephant
