mysql 转义字符特殊字符

RT,通常php+mysql的单引号，“\”符号插入一般采用addslashes()方式

假如，现在插入$varstr = test'\，问题如下：
1.带addslashes(),insert插入后在mysql中存放格式是 test'\，还是 test\'\\？

3.select出来后，echo $varstr;显示是 test'\，还是 test\'\\？

2.selelct以该变量字符串为条件查询时，是否需要加addslashes()？

mysql关于转义字符问题，很头疼，希望专家出来点拨下，谢了！

回复讨论(解决方案)

ls这个是另外一种转义方式，我说的是addslashes方式。
除了以上3个问题其实还有很多需要注意的细节,经常容易混淆。。
如：echo "\\\\\\\\\"stripslashes处理各种奇怪现象。

求专家梳理。

在mysql中存放格式是test'\
echo $varstr;显示是test'\

selelct以该变量字符串为条件查询时，是否需要加addslashes()？
