[SOLVED] foreach in a text file

Hey guys

I've written a standard php-mysql driven 'members' script to allow "registered" members access to certain parts of my site, which works like a charm, only thing I'd like to restrict registration to usernames already approved'

So far I've managed to do it by putting this in the script >

//if the name does not exist it gives an error
if ($check2 != 0) {
die('Sorry, the username '.$_POST['username'].' is already in use.');
}
//if username equals a clan member
if($_POST['username'] == 'A Clan members name I have to manually insert into the script here') {
}
else {
     die ('The username you have submitted does not have the permissions to access this resource....} 
//carry on if that name == A Clan members name

Only problem with this way I have to do it 50 times for each clan member, which is pretty messy as you could imagine. So to get around the messy part I have the names of those names allowed in a text file (one per line) and am trying to get the script to check the name submitted in the registration form against a name in the text file.

So far I have this >

//if the name exists it gives an error
if ($check2 != 0) {
die('Sorry, the username '.$_POST['username'].' is already in use.');
}
//if username equals a clan member
$lines = file('names.txt');
foreach ($lines as $line_num) => $line)
if($_POST['username'] == $line) {
}
else {
     die ('The username you have submitted does not have the permissions to access this resource....} 
//carry on if that name == A Clan members name

My problem is, is that it's refusing access to any name, whether on the list or not. Can anybody see where I'm going wrong??

Okay.. Try it like this.

Your file is like this:

member1||member2||member3||member4||member5||member6||member7

etc etc...

Then you can do it like so:

$names = explode("||", file_get_contents("names.txt")); //put each name into an array

if(in_array($_POST['username'],$names)){
die("Name is a clan member name!");
}else{
//its all good!
}

Or you can just build the array yourself...

$names = array("member1","member2","member3","member4","member5");

if(in_array($_POST['username'],$names)){
die("Name is a clan member name!");
}else{
//its all good!
}

Went for your first example..

All I can say is,, Man, that is sweet, works like a charm, thankyou very much, I've been at this for hours, and would have logged a few more if it weren't for you..

Cheers

First one is easier.

Glad to help.

Good luck.

Thanks again

might give your second example tomorrow (when I'm a little more sober   )

But just out of curiousness could I arrange my 'names.txt' file so that every name is on a new line and change the script so that it looks like this>

names = explode("\rn", file_get_contents("names.txt")); //put each name into an array

if(in_array($_POST['username'],$names)){
die("Name is a clan member name!");
}else{
//its all good!
}

"explode("\rn""      is for a new line???

I'm still a PHP newbie but \rn is a new line isn't it??

Just curious here!!

If you have usernames on separate lines within a text file, use file() instead:

$names = array_map('trim', file('names.txt'));

if(in_array($_POST['username'], $names)){
die("Name is a clan member name!");
}else{
//its all good!
}

^^

Thanks Wildteen88, but that didn't work for me.

I've ended up using ProjectFears code >

$names = explode("||", file_get_contents("names.txt")); //put each name into an array
if(in_array($_POST['username'],$names)){
die("Name is a clan member name!");
}else{
//its all good!
}

And arranging my names.txt file to look like this:

||name1||

||name2||

||and so on||

Works fine, problem solved.

Thanks
