I think you can try to sort the array in reverse order, and then calculate the sum of numbers in loops (end loop when the sum is larger than target sum). It seems there is no algorithm can do this quickly. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you only want to replace the line including url(s) by a message, a
simple regular expression is enough.
http://www.example.com/\";>example line.\n"
. "Another line.\n"
. "http://www.e.com/ads/show?n=123\";>123 (456)\n"
. "End Line.\n";
$melding = preg_replace("/.*?", $melding);
echo $melding;
?>
The script above will output:
This is a spam.
Another line.
End Line.

You'd better learn the basic knowledge of PHP. There are several obvious
mistakes in your code.
> $dBInsert = new dBInsert('wl_admins', '$sql');
> $dBInsert->InsertDB('$sql');
Note that variables will *not* be expanded when they occur in single
quoted strings.
> $this->table = $table;
> $this->sql = $sql;
The two variables seemed useless.
> $conn->debug=1;
> $conn = &ADONewConnection('mysql');
Called $conn before creating it.
And, I could not to know what is the purpose of this class.
PS, a description such as "it's not working" is useless for solving the
problem.

This is my ideas:
If the file has already existed, the server-side script could save it in
a place temporarily, and marks the file by an unique identification
(such as md5 checksum). And then the the server-side tells the
client-side file exists and gives it the id. If the user choose
overwrite, the client-side only need to post the received id, do not
need to upload the file again.

The regex you wrote lacks separator. That PHP statement will occur an
error:
> Warning: preg_match() [function.preg-match]: Unknown modifier ']' in
> /path/file.php on line X
The statement should be:
preg_match("/]*>(.*?)<\/h1>/i", "Welcome to my homepage",
$matches, PREG_OFFSET_CAPTURE);
print_r($matches);
