Complete PHP Array Reference
Definition and Usage
The array_uintesect_assoc() function compares two or more arrays, both in a built in function and in a user-made function, and then returns an array containing the elements from the first array, if the functions allow it. The built in function compares the keys. The user-made function compares the values, and returns a numeric value, 0 if the returned array should contain this element.
Syntax
array_uintersect_assoc(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: For comparison, the key is used in the built-in function and the value is used in the user-made function.
Example
<?php
function myfunction($v1,$v2)
{
if ($v1===$v2)
{
return 0;
}
return 1;
}
$a1=array("a"=>"Cat","b"=>"Dog","c"=>"Horse");
$a2=array("a"=>"Cat","b"=>"Horse","c"=>"Dog");
print_r(array_uintersect_assoc($a1,$a2,"myfunction"));
?>
function myfunction($v1,$v2)
{
if ($v1===$v2)
{
return 0;
}
return 1;
}
$a1=array("a"=>"Cat","b"=>"Dog","c"=>"Horse");
$a2=array("a"=>"Cat","b"=>"Horse","c"=>"Dog");
print_r(array_uintersect_assoc($a1,$a2,"myfunction"));
?>
The output of the code above will be:
Array ( [a] Cat )
