Opening Source Code of a Remote Site

[Daleeburg]

I have a newsite, that i like to follow, but it is constantly changing.

 

Basically I want to make a feed of sorts, but the site does not offer a feed, is there a way that I can take the source of a certain page then have a function that looks through the code for links and come out with just the links.

 

more or less i have an idea of how to do the search function, but i was wondering about the retrieving the other page, is it possible?  And if so, how?

 

thx

<?php

function textbetweenarray($s1,$s2,$s){
  $myarray=array();
  $s1=strtolower($s1);
  $s2=strtolower($s2);
  $L1=strlen($s1);
  $L2=strlen($s2);
  $scheck=strtolower($s);

  do{
  $pos1 = strpos($scheck,$s1);
  if($pos1!==false){
$pos2 = strpos(substr($scheck,$pos1+$L1),$s2);
if($pos2!==false){
  $myarray[]=substr($s,$pos1+$L1,$pos2);
  $s=substr($s,$pos1+$L1+$pos2+$L2);
  $scheck=strtolower($s);
  }
	}
  } while (($pos1!==false)and($pos2!==false));
return $myarray;
}

$externalcontent = file_get_contents("http://www.google.co.uk");

$as = textbetweenarray("<a href=\"", "</a>", $externalcontent);
$output = array();

foreach($as as $a) {
$output[] = "<a href=\"$a</a>";
}

echo "<pre>";

foreach($output as $link) {
echo "$link\n";
}

echo "</pre>";

?>

 

That outputs each link on Google

K so i took part of the code you proposed and tried to change it, now it doesnt work.

 

<?php

function textbetweenarray($s1,$s2,$s){

  $myarray=array();
  $s1=strtolower($s1);
  $s2=strtolower($s2);
  $L1=strlen($s1);
  $L2=strlen($s2);
  $scheck=strtolower($s);
  $disallow = '</strong></a>';
  
  do{
  $pos = strpos($scheck,$disallow);  // this is line 21
  if($pos!==false){
$pos1 = strpos($scheck,$s1);
if($pos1!==false){
	$pos2 = strpos(substr($scheck,$pos1+$L1),$s2);
	if($pos2!==false){
		$myarray[]=substr($s,$pos1+$L1,$pos2);
		$s=substr($s,$pos1+$L1+$pos2+$L2);
		$scheck=strtolower($s);
	}
}
  }
  } while (($pos1!==false)and($pos2!==false));
return $myarray;
}

?>

 

I am trying to filter out any strings that include

</strong></a>

but i get a fatal error at line 21 , it says that it took to long to run.
