How to remove numbers from string in php

php去除字符串中数字的方法:

这个比较简单,但是也有些需要注意的地方,先贴代码

$class=preg_replace("\\d+",'', $res);

需要使用preg_replace函数,但是只是这么写的话,会报错

Warning: preg_replace(): Delimiter must not be alphanumeric or backslash

翻译过来就是定界符不能是字母数字或反斜线。

想了一下,在正则表达式首尾加了一对/

$class=preg_replace("/\\d+/",'', $res);

这样就成功了
