Need help Making Script Work

[ojsimon]

Hi
I found this script on a forum and have been trying to make it work, but all it returns is a blank screen, i tried using the debug error reporting but got nothing from that either just a blank page, here is the code[PHP]<?php
//In this case, it fetches a search for "fresh content" from www.alltheweb.c om, whom we hope you will visit.
$theLocation="h ttp://www.alltheweb.c om/search?cat=web& q=fresh+content &phrase=on&h=50 ";
//Below, at $start and $finish, you'll enter the start and finish points in the remote HTML.

$startingpoint = "<td valign=top>&nbs p;1.&nbsp;&nbsp ;</td>"; // replace inside the quotes with with your unique start point in the source of the HTML page. It HAS to be unique.
$endingpoint = "<span class=rh>Result s:</span></b>&nbsp;&nbsp;" ; // replace with the unique finish point in the source of the HTML page
//Don't forget to escape any " marks with a \ mark.
// Example: If the starting HTML is: <img src="images/something.jpg">
// You would tell Mini-Fetch: $startingpoint = "<img src=\"images/something.jpg\" >";

//That's probably all you need to edit, unless you want to match and replace certain text or HTML.

// - "Don't touch this part..."
preg_match("/^(https?:\/\/)?([^\/]*)(.*)/i", "$theLocati on", $matches);
$theDomain = "http://" . $matches[2];
$page = $matches[3];

$fd = fopen($theDomai n.$page, "r"); // can change to "rb", on NT/2000 servers, if problems.
$value = "";
while(!feof($fd )){
$value .= fread($fd, 4096);
}
fclose($fd);
$start= strpos($value, "$startingpoint ");
$finish= strpos($value, "$endingpoint") ;
$length= $finish-$start;
$value=substr($ value, $start, $length);
// end "don't touch this part"


// eregi_replace, below, is a case-insensitive function to find, match, and replace variations of text that you define.
//The following commands strip or replace HTML tags.

// $value = eregi_replace( "<img src=[^>]*>", "", $value ); // Remove all image tags. This is disabled until you remove the // in front of this line.
$value = eregi_replace( "<IMG alt=[^>]*>", "", $value ); // Remove all image alt="whatever" tags

// Below - what's the difference, you ask, between eregi_replace and str_replace?
// str_replace is faster, by a long shot... The catch is that in can only be used
// to replace EXACT value matches, as you see below, and doesn't work well in huge files without using arrays.

$FinalOutput = preg_replace("/(href=\"?)(\/[^\"\/]+)/", "\\1" . $theDomain . "\\2", $value);
echo $FinalOutput; //prints it to your page
flush (); //force output to your page faster

This is your problem here:
[PHP]$value =substr($value, $start, $length);[/PHP]

Your String $value is not right Take a look at your while statement. Notice the string $value . in that statement.
