RE: [PHP] Re: grabbing information from websites

[Graham Cossey]

OK, I've tried it out. What is interesting is that the URL you have posted
results in the site's 'home' page, for me anyway, which obviously results in
no matches for the preg_match. It appears to redirect to
http://www.runescape.com/ somehow.

I am using the code:

<?php
$content =
file_get_contents("http://hiscore.runescape.com/aff/runescape/hiscorepersona
l.cgi?username=champinoman");
if
(preg_match('#username=champinoman&category=13.*align="right">(.*)</td>#mi',
$content,$out))
{
        echo $out;
}else{
        echo $content;  // <- results in home page
}
?>

i tried putting in fread() but still getting a blank screen. any other
errors in here?

<?php
$file = fopen
("http://hiscore.runescape.com/aff/runescape/hiscorepersonal.cgi?username=ch
ampinoman","r");
$line = fread ($file, 1024);
if
(preg_match('#username=champinoman&category=13.*align="right">(.*)</td>#mi',
$line,$out))
{
$rune = $out;
}
fclose($file);
print $rune;
?>
