php 入库时没有加 反斜杠怎么办?

PHP 数据中的反斜杠插入数据库后消失了

原因就是:

反斜杠(\ )需要进行转义。

列入:

INSERT INTO `stu` VALUES('lisi',   'school\class\stu_num',  '188/900');
Copy after login

这样直接插入数据库不行

所以用了addcslashes();

例如:

$deatil = addcslashes($detail,"\\");
INSERT INTO `stu` VALUES("$name",   "$detail",  "$else");
Copy after login

另外想到了magic_quotes_gpc 函数,所以提一下:

这个特性在PHP5.3.0中已经废弃并且在5.4.0中已经移除了(This feature has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.)。所以没有理由再使用魔术引号,因为它不再是 PHP 支持的一部分。 不过它帮助了新手在不知不觉中写出了更好(更安全)的代码。 但是在处理代码的时候,最好是更改你的代码而不是依赖于魔术引号的开启。
