Definition

The array_udiff_uassoc() function uses two user-defined functions to compare the keys and values of two or more arrays, and returns the differences.

Syntax

PHP array_udiff_uassoc() Function has the following syntax.

Parameter

myfunction_key and myfunction_value must return an integer <, =, or > than 0 if the first argument is <, =, or > than the second argument.

Example

Uses two user-defined functions to compare the keys and values of two or more arrays, and returns the differences

<?php/*from j  av  a  2  s  .c om*/
function myfunction_key($a,$b){
    if ($a===$b){
      return 0;
    }
    return ($a>$b)?1:-1;
}

function myfunction_value($a,$b){
    if ($a===$b){
      return 0;
    }
    return ($a>$b)?1:-1;
}

$a1=array("a"=>"A","b"=>"HTML","c"=>"java2s.com");
$a2=array("a"=>"Apple","b"=>"CSS","e"=>"PHP");

$result=array_udiff_uassoc($a1,$a2,"myfunction_key","myfunction_value");
print_r($result);
?>

The code above generates the following result.
