PHP array_diff_assoc() Function

The array_diff_assoc() function is used to compare an array against another array and returns the difference. Unlike array_diff() the array keys are also used in the comparison.

This function compares the keys and values of two (or more) arrays, and return an array that contains the entries from array1 that are not present in array2 or array3, etc.

Syntax

 array_diff_assoc(array1,array2,array3...);

Example

$array1=array("a"=>"Prince","b"=>"James","c"=>"Samuel","d"=>"Cooper");
$array2=array("a"=>"Prince","b"=>"James","c"=>"Samuel");
$result=array_diff($array1,$array2);
print_r($result);

Output

Array ( [d] => Cooper )
