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

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
