PHP array_intersect_ukey() Function

Definition and Usage

The array_intersect_ukey() function compares the keys in two or more arrays, checking for matches, before comparing the keys in a user-defined function, then returns an array with the keys and values from the first array, if the function allows it.

Syntax

array_intersect_ukey(array1,array2,array3...,function)

Parameter	Description
array1	Required. The first array is the array that the others will be compared with
array2	Required. An array to be compared with the first array
array3	Optional. An array to be compared with the first array
function	Required. The name of the user-made function

Tips and Notes

Tip: You can compare the first array with one array, or as many as you like.
Note: Only the keys have to be the same to get a match, both in the automatic comparison and in the user-defined function.

Example 1

<?php
function myfunction($v1,$v2)
{
if ($v1===$v2)
  {
  return 0;
  }
if ($v1>$v2)
  {
  return 1;
  }
else
  {
  return -1;
  }
}
$a1=array(0=>"Dog",1=>"Cat",2=>"Horse");
$a2=array(3=>"Rat",1=>"Bird",5=>"Monkey");
print_r(array_intersect_ukey($a1,$a2,"myfunction"));
?>

OUTPUT :
