  1、php中单引号和双引号的区别,哪个速度更快?为什么?(考php基本功)

  2、不用新变量直接交换现有两个变理的值。 (考php基本功)

  3、PHP数字金额转大小格式,同时说明思路 (考数组掌握)

  4、SQL查询语句如下:

  select * from table where (ID = 10) or (ID = 32) or (ID = 22) or (ID = 76) or (ID = 13) or (ID = 44)

  让结果按10,32,22,76,13,44的顺序检索出来,请问如何书写? (sql能力)

  5、简单写一个上传文件程序,要求同时上传文件数量可以人为控制 (逻辑能力)

  6、php同时调用3个数据库中的一个表的信息(架设A.a.aid=B.b.bid=C.c.cid),请说明思路及书写部分代码

  7、现有一IM软件,使用id、email做为注册条件,假设已注册1040人,有一zh_cn论坛,使用id、email做为注册条件,假设已注册200人,有一en_us论坛,使用id、email做为注册条件,假设已注册150人

  要求:将三者同步,使用统一的注册流程 ,写出设计思路

  8、 a. 写一句脚本,分析apache的access.log,得出访问量最高文件前5名 (Unix/Apache)

  b. 创建一个数据库,里面有一张表(见后面),并将其授权给所有192.168.1.*网段的用户

  表需求:每天文件访问情况,包括文件名、访问IP、访问时间、客户端浏览器名称,考虑

mPDF

mPDF

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),
