PHP：如何使用str_replace

问题描述：

I am trying to string replace the following in php

{{str_replace('D:\xamp\htdocs\james\', '/', 'D:\xamp\htdocs\james\assets/images/users/58f5f0afc28cb-bigbang2.jpg')}}

I get the following error:

ErrorException: Parse error: syntax error, unexpected 'D' (T_STRING), expecting ',' or ')'

How can I achieve this?

我正在尝试将字符串替换为php中的以下内容 p>

   {{str_replace（'D：\ xamp \ htdocs \ james \'，'/'，'D：\ xamp \ htdocs \ james \ assets / images / users / 58f5f0afc28cb-bigbang2.jpg'）}} 
  code  >  pre> 
 
 我收到以下错误： p> 
 
 
 
  ErrorException：Parse error：语法错误，意外'D'（T_STRING）， 期待'，'或'）' p> 
  blockquote> 
 
 
我如何实现这一目标？ p> 
  div>

答

Instead of preg_replace use str_replace for exact matching and replacement. Problem in your code is you haven't escaped \ use first parameter as 'D:\xamp\htdocs\james\\'

echo str_replace('D:\xamp\htdocs\james\\', '/', 'D:\xamp\htdocs\james\assets/images/users/58f5f0afc28cb-bigbang2.jpg');

Output:

/assets/images/users/58f5f0afc28cb-bigbang2.jpg

答

The ' is getting escaped here: 'D:\xamp\htdocs\james\'. That is the reason you are getting the error. You need to escape the \ to resolve the error.

{{preg_replace('D:\xamp\htdocs\james\\', '/','D:\xamp\htdocs\james\assets/images/users/58f5f0afc28cb-bigbang2.jpg')}}
