array_uintersect()()

The array_uintersect() function compares the values of two or more arrays, and returns the matches.

Syntax:
array_uintersect(array1,array2,array3...,myfunction)

In above syntax, "array1" is the array to compare from, "array2" is an array to compare against, "array3,..." and more arrays to compare against and "myfunction" is a string that define a callable comparison function. The comparison function must return an integer <, =, or > than 0 if the first argument is <, =, or > than the second argument

Example:

<?php
function myfunction($a,$b)
{
if ($a===$b)
   {
   return 0;
   }
   return ($a>$b)?1:-1;
}
$a1=array("a"=>"Apple","b"=>"Mango","c"=>"Orange");
$a2=array("a"=>"Orange","b"=>"Banana","e"=>"Orange");
$result=array_uintersect($a1,$a2,"myfunction");
print_r($result);
?>

Output:

Array ( [c] => Orange )

array_uintersect_assoc()

The array_uintersect_assoc() function compares the keys and values of two or more arrays, and returns the matches.

Syntax:
array_uintersect_assoc(array1,array2,array3...,myfunction)

In above syntax, "array1" is the array to compare from, "array2" is an array to compare against, "array3,..." and more arrays to compare against and "myfunction" is a string that define a callable comparison function. The comparison function must return an integer <, =, or > than 0 if the first argument is <, =, or > than the second argument

Example:

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

$a1=array("a"=>"Apple","b"=>"Mango","c"=>"Orange");
$a2=array("a"=>"Apple","b"=>"Orange","c"=>"Mango");

$result=array_uintersect_assoc($a1,$a2,"myfunction");
print_r($result);
?>

Output:

Array ( [a] => Apple )

 

array_uintersect_uassoc()

The array_uintersect_uassoc() function compares the keys and values of two or more arrays, and returns the matches.

Syntax:
array_uintersect_assoc(array1,array2,array3...,myfunction_key,myfunction_value)

In above syntax, "array1" is the array to compare from, "array2" is an array to compare against, "array3,..." and more arrays to compare against and "myfunction_key" is the name of the user-defined function that compares the array keys. A string that define a callable comparison function. The comparison function must return an integer <, =, or > than 0 if the first argument is <, =, or > than the second argument and "myfunction_value" the name of the user-defined function that compares the array values. A string that define a callable comparison function. The comparison function must return an integer <, =, or > than 0 if the first argument is <, =, or > than the second argument

Example:

<?php
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"=>"Apple","b"=>"Mango","c"=>"Orange");
$a2=array("a"=>"Apple","b"=>"Mango","c"=>"Mango");

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

Output:

Array ( [a] => Apple [b] => Mango )
