Examples
Example #1 array_diff_assoc example In this example you see the "a" => "green" pair is present in both arrays and thus it is not in the output from the function. Unlike this, the pair 0 => "red" is in the output because in the second argument "red" has key which is 1.
<?php The above example will output: Array ( [b] => brown [c] => blue [0] => red )
Example #2 array_diff_assoc example Two values from key => value pairs are considered equal only if (string) $elem1 === (string) $elem2 . In other words a strict check takes place so the string representations must be the same.
<?php The above example will output: Array ( [0] => 0 [1] => 1 ) Notes
