What is array_merge Function?
|
|
Explanation |
The "array_merge" function is used to merge one or more arrays.
Syntax:
array_merge(array1,array2,array3...)
In the above syntax atleast one array is mandatory, other arrays are optional.
Example
<?php
$a=array("a"=>"Orange","b"=>"Guava", "d"=>"Jackfruit");
$b=array("c"=>"Cherry","b"=>"Strawberry", "d"=>"berry");
print_r(array_merge_recursive($a,$b));
?>
Result:
Array ( [a] => Orange [b] => Strawberry [c] => Cherry [d] => berry))
In the above example both arrays "$a","$b" have some common keys that is "b", "d", last value of that key
overrides the previous value.
