Definition

The array_uintersect_assoc() function uses a user function to compare the keys and values of two or more arrays, and returns the matches.

Syntax

PHP array_uintersect_assoc() Function has the following syntax.

Parameter

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

Example

Uses a user function to compare the keys and values of two or more arrays, and returns the matches

    function myfunction($a,$b){
       if ($a===$b){
          return 0;
       }
       return ($a>$b)?1:-1;
    }
    
    $a1=array("a"=>"A","b"=>"B","c"=>"C");
    $a2=array("a"=>"A","b"=>"X","c"=>"java2s.com");
    
    $result=array_uintersect_assoc($a1,$a2,"myfunction");

?>

The code above generates the following result.
