我有一个简单的问题，但已经被锁了几个小时...我有一个Wordpress数据库，想更新usermeta表。
该值是使用maybe_serialize（）WP函数的序列化值。 我的更新查询每次都会失败。我尝试了多种方法来逃避值，但这是行不通的。
这是我要生成的最终MySQL查询（由PhpMyAdmin生成）：
UPDATE `mytable` SET `meta_value` = 'a:2:{s:64:\"261d0952a424f1e8ef27ee77ef505c445c0aac5166f67e8d675bf06f717972d2\";a:4:{s:10:\"expiration\";i:1526328393;s:2:\"ip\";s:14:\"212.71.232.248\";s:2:\"ua\";s:117:\"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/11.1 Safari/605.1.15\";s:5:\"login\";i:1525118793;}s:64:\"6f04a963506c545e0fb307135bd2eaf5178c8830c55048bb5d80cb7a8d730507\";a:4:{s:10:\"expiration\";i:1525556847;s:2:\"ip\";s:14:\"212.71.232.248\";s:2:\"ua\";s:121:\"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36\";s:5:\"login\";i:1525384047;}}' WHERE `mytable`.`umeta_id` = 48;
meta_value的原始内容是：
a:2:{s:64:"261d0952a424f1e8ef27ee77ef505c445c0aac5166f67e8d675bf06f717972d2";a:4:{s:10:"expiration";i:1526328393;s:2:"ip";s:14:"212.71.232.248";s:2:"ua";s:117:"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/11.1 Safari/605.1.15";s:5:"login";i:1525118793;}s:64:"6f04a963506c545e0fb307135bd2eaf5178c8830c55048bb5d80cb7a8d730507";a:4:{s:10:"expiration";i:1525556847;s:2:"ip";s:14:"212.71.232.248";s:2:"ua";s:121:"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36";s:5:"login";i:1525384047;}}
如何在PHP中对其进行转义以获取与MySQL一起使用的最终所需查询？我尝试了mysqli_real_escape_string（），但是不一样。
编辑：这是mysqli_real_escape_string（）之后的数组结果
$ a:2:{s:64:\"261d0952a424f1e8ef27ee77ef505c445c0aac5166f67e8d675bf06f717972d2\";a:4:{s:10:\"expiration\";i:1577790000;s:2:\"ip\";s:14:\"212.71.232.248\";s:2:\"ua\";s:117:\"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/11.1 Safari/605.1.15\";s:5:\"login\";i:1525118793;}s:64:\"6f04a963506c545e0fb307135bd2eaf5178c8830c55048bb5d80cb7a8d730507\";a:4:{s:10:\"expiration\";i:1577790000;s:2:\"ip\";s:14:\"212.71.232.248\";s:2:\"ua\";s:121:\"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36\";s:5:\"login\";i:1525384047;}}
如您所见，转义与PhpMYAdmin在第一个查询中生成的转义不同。
谢谢！
