I have 2 scripts

The first one works fine with google.com (gets the text anyway) but does not grab anything from switchboard.com.

Code: 
$GrabURL = "[URL unfurl="true"]http://www.DOMAIN.com";[/URL]  //-  Complete URL Of The Page You're Grabbing From!
$GrabStart = "<html>";  //- HTML Code To Start Grab. Must Be A Unique Bit Of Code!
$GrabEnd = "</html>";  //- HTML Code To End Grab. Must Be A Unique Bit Of Code!

$OpenFile = fopen("$GrabURL", "r"); //- DO NOT CHANGE
$RetrieveFile = fread($OpenFile, 200000);  //- Reduce This To Save Memory
$GrabData = eregi("$GrabStart(.*)$GrabEnd", $RetrieveFile, $DataPrint);
// $DataPrint[1] = str_replace("", "", $DataPrint[1]);   //- Un-Comment This Line for "Replace" purposes!
// $DataPrint[1] = str_replace("", "", $DataPrint[1]);   //- Un-Comment This Line for "Replace" purposes!
fclose($OpenFile); //- DO NOT CHANGE
echo $DataPrint[1]; //- DO NOT CHANGE


This script works just fine:

Code: 
include("[URL unfurl="true"]http://www.switchboard.com");[/URL]


Is it possible that fopen or fread is blocked by switchboard.com? If so, is there any workaround?

Thanks, Mike

It's certainly possible.


A content filter on your network could be blocking access to one but not the other.

DNS problems could be blocking it.

It's possible, too, I guess, that the server at switchboard.com doesn't like the web client identifier PHP sends and is cutting you off.


I don't know how much access you have to the server which is running PHP, but if you can, try accessing switchboard.com from another application on the server.

I have full access to the server, and I use a perl spider to access switchboard.com all the time.

How are you testing that nothing is being fetched? If I change your posted code, replacing:

echo $DataPrint[1]; //- DO NOT CHANGE

with

echo $RetrieveFile; //- DO NOT CHANGE


I get content. It looks to me like it's your eregi() invocation that's causing the problem.
