How do you get a part of webpage from remote by using php?
<p>Id like to get a part of webpage. 
Let me show you what id like to do.</p>

<p>For example, http:// www.xxxxxx.com/page=2</p>

<p>As you can see there is a list, and this list shows 50 ads. Please ignore other ones. Every ads have an unique id in their links.</p>

<p>for example: </p>

<blockquote>
  <p>http:// xxx.com/-iid-155546130</p>
</blockquote>

<p>the id number is : 155546130</p>

<p>Okay, id like to get unique id numbers from that page, and echo them to the screen. So, i need to get 50 unique ids from that page. Only id numbers.</p>

<p>well, could you please kindly give me some advice? which functions should i use? how can i do that job?</p>

<p>Regards.</p>
