PHP array_uintersect_uassoc() Function

Complete PHP Array Reference

Definition and Usage

The array_uintersect_uassoc() function compares two or more arrays, in two user-made functions, and returns an array containing the elements from the first array, if the user-made functions allow it. The first user-made function compares array keys, and the second compares array values, and both returns a numeric value, 0 if the returned array should contain this element.

Syntax

array_uintersect_uassoc(array1,array2,array3...,function1,function2)

Tips and Notes

Tip: You can compare the first array with one array, or as many as you like.

Note: For comparison, the key is used in the first function and the value is used in the second. They are both user-made functions.

Example

<?php
function myfunction_key($v1,$v2) 
{
if ($v1===$v2)
	{
	return 0;
	}
return 1;
}

function myfunction_value($v1,$v2) 
{
if ($v1===$v2)
	{
	return 0;
	}
return 1;
}
$a1=array("a"=>"Cat","b"=>"Dog","c"=>"Horse");
$a2=array("a"=>"Cat","b"=>"Dog","c"=>"Dog");
print_r(array_uintersect_uassoc($a1,$a2,"myfunction_key","myfunction_value"));
?>

The output of the code above will be:

Array ( [a] => Cat [b] => Dog )
