Beispiel #1 Using wincache_ucache_delete() with key as a string
<?php
wincache_ucache_set('foo', 'bar');
var_dump(wincache_ucache_delete('foo'));
var_dump(wincache_ucache_exists('foo'));

bool(true) bool(false)
Beispiel #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));
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
array(4) { [0]=> string(5) "green"
[1]=> string(4) "Blue"
[2]=> string(6) "yellow"
[3]=> string(4) "cyan" }
Beispiel #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));
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
array(2) { [0]=> string(6) "yellow"
[1]=> string(4) "cyan" }
