I’ve got some (admittedly) messy code that reads name/password entries from a textfile and displays them to the administrator:

```auto

$changed [/COLOR][COLOR=#007700]= [/COLOR][COLOR=#0000BB]false[/COLOR][COLOR=#007700];

[/COLOR][COLOR=#FF8000]# do we want to delete a record
[/COLOR][COLOR=#007700]if (isset([/COLOR][COLOR=#0000BB]$_GET[/COLOR][COLOR=#007700][[/COLOR][COLOR=#DD0000]'delid'[/COLOR][COLOR=#007700]])) {

    [/COLOR][COLOR=#FF8000]# remove deleted item from the array
    [/COLOR][COLOR=#007700]unset([/COLOR][COLOR=#0000BB]$fp[/COLOR][COLOR=#007700][[/COLOR][COLOR=#0000BB]$_GET[/COLOR][COLOR=#007700][[/COLOR][COLOR=#DD0000]'delid'[/COLOR][COLOR=#007700]]]);
    [/COLOR][COLOR=#0000BB]$changed [/COLOR][COLOR=#007700]= [/COLOR][COLOR=#0000BB]true[/COLOR][COLOR=#007700];
}

if ([/COLOR][COLOR=#0000BB]$changed[/COLOR][COLOR=#007700]) {

             foreach ([/COLOR][COLOR=#0000BB]$dataArray [/COLOR][COLOR=#007700]as [/COLOR][COLOR=#0000BB]$k [/COLOR][COLOR=#007700]=> [/COLOR][COLOR=#0000BB]$v[/COLOR][COLOR=#007700]) {

             }

}

while (![/COLOR][COLOR=#0000BB]feof[/COLOR][COLOR=#007700]([/COLOR][COLOR=#0000BB]$fp[/COLOR][COLOR=#007700]) ) {

What I’m trying to figure out is how to mark any particular item for delete and remove that array from the textfile. The textfile named clients.txt looks like this:

```auto

frank	blowfish
sally	tuna

```

I can display the textfile entries to screen but I can’t quite figure out how to tag the individual items and successfully delete those entries. Here’s a Zip of the files I’m working with: [http://www.tornedgedesign.com/\_test/login/register.zip](http://www.tornedgedesign.com/_test/login/register.zip)

Help!
