array_merge() Function

Hi,

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

Description

array_merge(array1,array2,array3...)
array1 Required. Specifies an array
array2 Optional. Specifies an array
array3 Optional. Specifies an array

Tip: You can assign one array to the function, or as many as you like.

Note: If two or more array elements have the same key, the last one overrides the others.

Note: If you assign only one array to the array_merge() function, and the keys are integers, the function returns a new array with integer keys starting at 0 and increases by 1 for each value. (See example 2)

<?php
$a1=array("a"=>"Horse","b"=>"Dog");
$a2=array("c"=>"Cow","b"=>"Cat");
print_r(array_merge($a1,$a2));
?>
Array ( [a] => Horse => Cat [c] => Cow )

 

Thank you ... it is good function really .. it makes the arrays so simple
