Homephp教程php手册Thinkphp模板标签if和eq的区别和比较实例分析

这篇文章主要介绍了Thinkphp模板标签if和eq的区别和比较,实例分析了Thinkphp模板标签if和eq用于变量比较的区别,需要的朋友可以参考下

本文实例讲述了Thinkphp模板标签if和eq的区别和比较。分享给大家供大家参考。具体分析如下:

在TP模板语言中。if和eq都可以用于变量的比较。总结以下几点:

1.两个变量的比较:

前者的IF是判断失败的,用后者的(或)则OK。需要注意:name那里是不用加$变量符号的,而value那里要加$变量符号。

2.还有值为空(NULL)的时候:

just a test just a test

前者的IF是判断失败的,,用后者的(或)则可以识别null为""

3.多维数组且下标为0的时候:

just a test just a test

前者用IF是根本不能通过编译的,用后面的eq就可以

希望本文所述对大家基于ThinkPHP的php程序设计有所帮助。
