Re: [PHP] grabbing data from a site
Try this function, Ijust wrote it for the same purpose. You just need a
unique string in front of the stuff you want, and one after it. You
can usually get a string of code on either end that will do this. The
function will open the URL, find the anchor strings you told it, then
strip them away leaving only the text/code that was in between them
?
function get_item($url, $start, $end) {
global $item;
if(!($fp=fopen($url,r))) {
echo $url. is not accessable;
exit;
}
while(!feof($fp)) {
$item.=fgets($fp,255);
}
fclose($fp);
$start_position=strpos($item, $start)+strlen($start);
$end_position=strpos($item, $end);
$length=$end_position-$start_position;
$item=substr($item, $start_position, $length);
}
echo $item;
?

If the target is in well-formed XML (XHTML is an example), you could use
XSLT
to say 'i want the third column of a particular row - in this instance,
Melbourne'. However, since few people actually adhere to standards, you're
probably going to need a regex... if you're not comfortable with them,
explode() could be useful (although it is slower)
Somebody posted an extremely helpfull little quick reference at
php.net/ereg,
i think... that might help you.

Say I wanted the current temperature for Melbourne from this table, what

expression...
i'm wondering whether there are ways of saying i want the third column
of
a particular row - in this instance, Melbourne?
Thanks for any help.
