Example #2 Usingwincache_ucache_delete() with key as an array
<?php
$array1 = array('green' => '5', 'blue' => '6', 'yellow' => '7', 'cyan' => '8');
wincache_ucache_set($array1);
$array2 = array('green', 'blue', 'yellow', 'cyan');
var_dump(wincache_ucache_delete($array2));

array(4) { [0]=> string(5) "green" 
           [1]=> string(4) "Blue" 
           [2]=> string(6) "yellow" 
           [3]=> string(4) "cyan" }
Example #3 Using wincache_ucache_delete() with key as an array where some elements cannot be deleted
<?php
$array1 = array('green' => '5', 'blue' => '6', 'yellow' => '7', 'cyan' => '8');
wincache_ucache_set($array1);
$array2 = array('orange', 'red', 'yellow', 'cyan');
var_dump(wincache_ucache_delete($array2));
?>Il precedente esempio visualizzerà:
array(2) { [0]=> string(6) "yellow"
