deleting some text from a file

[Anon]

Say I have a file containing the following list:

milk
eggs
cheese

I want to delete "eggs" from the file. How would I do this?

OK, say the name of the file is products.txt, here is what we do:

$datafile="produts.txt";
$file=file($datafile);
while(list(,$value)=each($file)){
list($prod)=split( "\n", $value);
$oldword="eggs"
$newword="";
$fp = fopen($datafile, "r");
$data = fread($fp, filesize($datafile));
fclose($fp);
$newdata = str_replace($oldword, $newword, $data);
$fp = fopen($datafile,"w");
fwrite($fp,$newdata) or die ("error writing");
fclose($fp);
}

This should delete ALL instances of "eggs" in your file. I have code similar to this on my webpage but I havn't tried erasing stuff with it! Hope this helps!

Here's a quick example, adjust accordingly :

deleteText('text.txt','eggs');

function deleteText($file,$delete_me)
{
if ( is_file($file) ) {

    $lines = file($file);

    foreach ($lines as $line) {

       if ( trim($line) != $delete_me ) {

           $words .= $line;
       }

    }

   $fp = fopen($file,'w');
   fwrite($fp,$words);
   fclose($fp);

} else {

   return FALSE:

}

}

Some things to consider. Error checking, Case sensitivity, and some other stuff I'm sure but it's time for bed :-)
