strrpos 与 strripos用法相同的,下面我们来看看吧.

定义和用法
该strrpos （ ）函数判断 find是否会出现在string里面。

这个函数如果存在的成功，否则返回FALSE 。

strrpos 语法

strrpos(string,find,start)
string:必需。指定字符串搜索


find:所需。指定的字符串找到


start:可选。指定从何处开始搜寻

注： strrpos （ ）函数是区分大小写

echo strrpos("Hello world!","wo");
?>
输出结果为6
再看一例子.
echo strrpos("WWW.111CN.CN!","cn");
?>
输出为0
知道为什么吗?因为strrpos区别大小小,它与strripos不同的是是否区别大小写.
