Example #1 apc_cas() example

<?php
apc_store
('foobar',2);
echo 
'$foobar = 2'PHP_EOL;
echo 
'$foobar == 1 ? 2 : 1 = ', (apc_cas('foobar'12) ? 'ok' 'fail'), PHP_EOL;
echo 
'$foobar == 2 ? 1 : 2 = ', (apc_cas('foobar'21) ? 'ok' 'fail'), PHP_EOL;

echo 
'$foobar = 'apc_fetch('foobar'), PHP_EOL;

echo 
'$f__bar == 1 ? 2 : 1 = ', (apc_cas('f__bar'12) ? 'ok' 'fail'), PHP_EOL;

apc_store('perfection''xyz');
echo 
'$perfection == 2 ? 1 : 2 = ', (apc_cas('perfection'21) ? 'ok' 'epic fail'), PHP_EOL;

echo 
'$foobar = 'apc_fetch('foobar'), PHP_EOL;
?>

The above example will output something similar to:

$foobar = 2
$foobar == 1 ? 2 : 1 = fail
$foobar == 2 ? 1 : 2 = ok
$foobar = 1
$f__bar == 1 ? 2 : 1 = fail
$perfection == 2 ? 1 : 2 = epic fail
$foobar = 1
