用preg_replace替换ereg_replace [英] replace ereg_replace with preg_replace

问题描述

您需要将函数ereg_replace("[\]", "", $theData)更改为preg_replace

Hi need to change the function ereg_replace("[\]", "", $theData) to preg_replace

推荐答案

要将端口ereg_replace移植到preg_replace，您需要将正则表达式放在一对定界符

To port ereg_replace to preg_replace you need to put the regex between a pair of delimiter

您的regx是[\]，无效，将用于preg_replace，因为\正在转义结束字符类]

Also your regx is [\] is invalid to be used for preg_replace as the \ is escaping the closing char class ]

正确的端口是

preg_replace('/[\\\]/','',$theData) 

此外，由于char类只有一个char，因此对char类没有真正的需求，您可以说:

Also since the char class has just one char there is no real need of char class you can just say:

preg_replace('/\\\/','',$theData) 

由于只替换一个字符，因此不建议使用正则表达式.您应该使用str_replace as

Since you are replace just a single char, using regex for this is not recommended. You should be using a simple text replacement using str_replace as:

str_replace('\\','',$data);
