修复使用包含颚化符（~）的URL时的脚本

Posted 2021-02-23

If you are using the [TimThumb](http://code.google.com/p/timthumb/ "TimThumb on Google Code") script with a URL the contains tildes (~) and images are breaking, here is the fix...

I did not create this snippet but found it extremely useful so I thought I'd make it available here. The URL listed is not mine but where I found it. Enjoy :-)

At line 209 (as of 01-29-13) in the script you will find the following line of code:

`$this->src = $this->param('src');`

Replace that line with the following snippet:

//check if tilde is found in src
if(strstr($this->param('src'),'~'))
{
   $url_parts = explode('/',$this->param('src'));
 
   foreach($url_parts as $url_part)
   {
      //do not include any part with a ~ when building new url
      if(!strstr($url_part,'~'))
      {
         $new_dev_url .= $url_part.'/';
      }
   }
 
   //remove trailing slash
   $new_dev_url = substr($new_dev_url,0,-1);
 
   $this->src = $new_dev_url;
}
else
{
   $this->src = $this->param('src');
}
