Question

Im trying to extract the values between eng_tid

and eng_data for http://fdguirhgeruih.x10.mx/html.txt and I keep getting T string errors.

why do I keep getting errors

<? php

    //First, open the file. Change your filename
    $file = "http://fdguirhgeruih.x10.mx/html.txt";
    $word1='tid';
    $word2='data';


    $handle = fopen($file, "r");
    $contents = fread($handle, filesize($file));
    fclose($handle);

    $between=substr($contents, strpos($contents, $word1), strpos($contents, $word2) - strpos($contents, $word1));

    echo $between; 


    ?>

UPDATE after seeing error messages...

Instead of fread() and attempting to use the size in bytes of your target file, you may simply use file_get_contents() to retrieve the remote file. Your error is because PHP wants to read the filesize of the file as though it is local, but it is a remote file over HTTP. filesize() reports 0 and an error. Instead do

// Don't do this...
//$handle = fopen($file, "r");
//$contents = fread($handle, filesize($file));
//fclose($handle);

// Instead do this...
$contents = file_get_contents($file);
