php中序列化与反序列化详解

$stooges = array('Moe','Larry','Curly');
$new = serialize($stooges);
print_r($new);echo "<br />";
print_r(unserialize($new));

$shopping = array('Poppy seed bagel' => 2,'Plain Bagel' =>1,'Lox' =>4);
echo '<a href="next.php?cart='.urlencode(serialize($shopping)).'" rel="external nofollow" >next</a>';

$new_cart = unserialize(stripslashes($cart)); //如果magic_quotes_gpc开启
$new_cart = unserialize($cart);

$fp = fopen('/tmp/cart','w');
fputs($fp,addslashes(serialize($a)));
fclose($fp);
//如果magic_quotes_runtime开启
$new_cat = unserialize(stripslashes(file_get_contents('/tmp/cart')));
//如果magic_quotes_runtime关闭
$new_cat = unserialize(file_get_contents('/tmp/cart'));

mysql_query("insert into cart(id,data) values(1,'".addslashes(serialize($cart))."')");
$rs = mysql_query('select data from cart where id=1');
$ob = mysql_fetch_object($rs);
//如果magic_quotes_runtime开启
$new_cart = unserialize(stripslashes($ob->data));
//如果magic_quotes_runtime关闭
$new_cart = unserialize($ob->data);
