问题描述

任何人都可以帮助我:

 <?php 
$ remove = $ _GET [' HWID'];
str_replace($ _ GET ['hwid']。< br />,,$ str);
?>

它甚至不删除文本...


解决方案

我知道我没有设置为html文件, / div>

假设你有这个文件(无论是从html还是其他形式)都可以这样做:

  $ str =HTML文件:

测试

Test1

Test2

Test3;

此功能将从字符串中删除Test2:

  $ newstr = str_replace(Test2,,$ str); 

有关该功能的更多信息,请查看 here



另外一件事,如果你有< br> 在你的例子中的每一行之后,你也需要做同样的事情。


ok can anyone help me with this:

<?php
$remove = $_GET['hwid'];
str_replace($_GET['hwid']."<br />","",$str);
?>

It doesnt even delete the text...

I Know i dont have it set to the html file i have thats because i don't know how to with this string...

解决方案

Let's say you have this as you retrieved text (whether from html or any other form):

$str="THE HTML FILE:

Test

Test1

Test2

Test3";

this function will remove "Test2" from the string:

$newstr=str_replace("Test2","",$str);

for more information of the function take a look at here

Just one more thing, if you have <br> after each line in your example, you need to do the same for those too.
