magic_quotes_gpc使用方法
magic_quotes_gpc使用方法
对于magic_quotes_gpc有两种情况,第一种就是
magin_quotes_gpc=on
与magin_quotes_gpc=off
下面我们就来举列说明.:
当magin_quotes_gpc=on时.
我们可以不对输入和输出数据库的字符串数据作 ,addslashes()和stripslashes()的操作,数据也会正常显示。
如果此时你对输入的数据作了addslashes()处理，那么在输出的时候就必须使用stripslashes()去掉多余的反斜杠。
2. 对于magic_quotes_gpc=off 的情况
必须使用addslashes()对输入数据进行处理，但并不需要使用stripslashes()格式化输出 因为addslashes()并未将反斜杠一起写入数据库，只是帮助mysql完成了sql语句的执行。
补充：
magic_quotes_gpc 作用范围是：ＷＥＢ客户服务端；作用时间：请求开始时，例如当脚本运行时．
magic_quotes_runtime 作用范围：从文件中读取的数据或执行exec()的结果或是从ＳＱＬ查询中得到的；作用时间：每次当脚本访问运行状态中产生的数据
