PHP function array_intersect_uassoc
This function compares two or more arrays by using the user-defined function. When the function doing the comparison, the function uses the user-defined function calls the first array key and value to compare with other arrays. It returns the array that match based on the user-defined function.
Syntax array_intersect_uassoc
- array1: array 1 uses for the comparison with all other arrays
- array2: second array
- array3: third array
- callback: user-defined function.
array_intersect_uassoc(array1, array2, array3, ...,callback);
Example 1
<?php
function callback($v1, $v2) {
if ($v1 == $v2) {
return 0;
} else if ($v1 > $v2) {
return 1;
} else {
return -1;
}
}
$play1 = array(30=>'bob', 40=>'jame', 50=>'smit', 20=>'king');
$play2 = array(30=>'bob', 42=>'smit', 40=>'jame', 32=>'king');
$play3 = array(40=>'jame', 30=>'bob', 1=>'king', 3=>'smit');
print_r(array_intersect_uassoc($play1, $play2, $play3, "callback"));
?>
Output
Array
(
[30] => bob
[40] => jame
)
Example 2
<?php
$class1 = array('A' => 13, 'B' => 31, 'cC' => 12, 'D' => 40);
$class2 = array('a' => 13, 'B' => 31, 'CC' => 12, 'D' => 40);
$class3 = array('A' => 13, 'b' => 31, 'cc' => 12, 'D' => 30);
$classes = array_intersect_uassoc($class1, $class2, $class3, "strcasecmp");
print_r($classes);
?>
Output
Array
(
[A] => 13
[B] => 31
[cC] => 12
)
Example 3
<?php
function callback($vl1, $vl2) {
if ($vl1 > $vl2) {
return 0;
} else {
return -1;
}
}
$p1 = array(14 => "banana", 1 => "apple", 12 => "coconut");
$p2 = array(4 => "banana", 1 => "apple", 5 => "coconut");
$p = array_intersect_uassoc($p1, $p2, "callback");
foreach($p as $n => $fruit ) {
echo "{$fruit} contains {$n}, and it is the largest.<br/>";
}
?>
Output
banana contains 14, and it is the largest. coconut contains 12, and it is the largest.
Example 4
<?php
function callback($vl1, $vl2) {
if ($vl1 < $vl2) {
return 0;
} else {
return -1;
}
}
$p1 = array(14 => "banana", 341 => "apple", 12 => "coconut");
$p2 = array(4 => "banana", 12 => "apple", 52 => "coconut");
$p = array_intersect_uassoc($p1, $p2, "callback");
foreach($p as $n => $fruit ) {
echo "{$fruit} contains {$n}, and it is the smallest.<br/>";
}
?>
Output
coconut contains 12, and it is the smallest.
