My objective here is I have to compare two hugeeeeee file ,so I want to sort them first and then trying to compare them (Will it optimize the search)
So already you guys showed me how to sort the input file to array .....so I have to copy the array to a file and then have to compare or can I compare two array directly
Please find the attached script for file comparison

My values are integers like 1, 2, 3, 4... and they are not unique, so I can't just reverse my hash and sort by keys.

array_diff_key
ARRAY_DIFF_KEY(3) 1 ARRAY_DIFF_KEY(3)array_diff_key - Computes the difference of arrays using keys for comparisonSYNOPSIS
array array_diff_key (array $array1, array $array2, [array $...])
DESCRIPTION
Compares the keys from $array1 against the keys from $array2 and returns the difference. This function is like array_diff(3) except the
comparison is done on the keys instead of the values.
PARAMETERS
o $array1
- The array to compare from
o $array2
- An array to compare against
o $...
- More arrays to compare against
RETURN VALUES
Returns an array containing all the entries from $array1 whose keys are not present in any of the other arrays.
EXAMPLES
Example #1
array_diff_key(3) example
The two keys from the key => value pairs are considered equal only if (string) $key1 === (string) $key2 . In other words a strict
type check is executed so the string representation must be the same.
<?php
$array1 = array('blue' => 1, 'red' => 2, 'green' => 3, 'purple' => 4);
$array2 = array('green' => 5, 'blue' => 6, 'yellow' => 7, 'cyan' => 8);
var_dump(array_diff_key($array1, $array2));
?>
The above example will output:
array(2) {
["red"]=>
int(2)
["purple"]=>
int(4)
}
NOTES
Note
This function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using
array_diff_key($array1[0], $array2[0]);.
