How to delete a word in a textfile?

[Anon]

Hey PHP-Guys!

I'm trying some hours but it don't work :-(

I would like to delete a word in a simple textfile. every word is in a single line,
e.g.

html
test
php
perl
asp

How to delete "perl"?

I know that i must use arrays, eregi and string replace etc but ...

How can help me with some lines of code?

Thanx a lot!

<?php
$dat = file("filename");

$fp = fopen("filename", "w");

for ($i = 0; $i < sizeof($dat); $i++) {

 if ($dat[$i] != "perl")
    fwrite($fp, $dat[$i]);

}
fclose($fp);
?>

That should do the trick.

Hey, i found this one in the forum...

it works, but don't remove the "\" after the searched word...

$oldword contains the word who should be deleted....

$list = "data.txt";
$results = file($list);
$newword = "";
while (list(,$path) = each($results)){
$parts = explode(':', $path);
$path = $parts[0];
$fp = fopen("$list", 'r');
if ($fp){
$data = fread($fp, filesize($list));
fclose($fp);
$newdata = str_replace($oldword, $newword, $data);
$fp = fopen($list, 'w');
if ($fp){
fwrite($fp, $newdata);
fclose($fp);
}
}
}

If I use my version incl. the removing of
the "\n" all "\n"'s in the file will be removed :-(
