Text-file line deleting?

[Anon]

Im a newbie to PHP and i need some help please....

If i have a text-file with lines of guestbook comments in them (name|email|url|comments) in a line e.t.c how would i make a loop to delete a selected line from the text-file?

[amcgrath]

$data = file($your_text_file);

while(list(,$line) = @each($data)) {
$pieces = explode('|',$line);
if ($piece[0] != 'Allen McGrath') {
// assumes you use the name as a value to delete
$new_file = implode('|',$line);
}
}

Now $new_file will be the file you cna write back to disk... not the prettiest, but it will work (Why not use a database instead?)

This will work better and it has the file opening/writing stuff Allen forgot.

$fp = fopen($newtextfile, "w");
$oldfile = file($oldtextfile);

foreach ($oldfile as $line) {
list($name,$email,$url,$comments) = split("|", $line);
if ($name != $name_to_remove) {
fwrite($fp,$line);
}
}
fclose($fp);
