Here it is
class groupClass {
var $groups = array();
var $gid = 499; //if there are no groups, new ones start at this
number +1
function groupClass($file){
$r = false;
if(file_exists($file)){
$in = file($file);
//build an array using names as keys so we can identify
entries easier
while(list($key,$val) = each($in)){
$val = trim($val); //get rid of newlines
list($name,$pass,$gid,$userlist) = split (":", $val);
if($gid > $this->gid){
$this->gid = $gid; //keep track
of the highest gid number
}
$this->groups[$name]['gid'] = $gid;
$this->groups[$name]['pass'] = $pass;
$users = explode(',',$userlist); //get an array
of users
while(list($key2,$user) = each($users)){
// build an array using name as key
$this->groups[$name]['users'][$user] = 1;
}
}
$r = true;
//debug
//echo '<pre>';
//print_r($this->groups);
//echo '</pre>';
}
Return $r;
}
function addGroup($group,$gid = 0,$pass = 'x'){
$r = false;
if(!isset($this->groups[$group])){
$gid = ($gid > 0)? $gid : $this->gid +1; // if no gid
then generate the next highest
$this->groups[$group]['gid'] = $gid;
$this->groups[$group]['pass'] = $pass;
$r = true;
}
Return $r;
}
function delGroup($group){
$r = false;
if(isset($this->groups[$group])){
unset($this->groups[$group]);
$r = true;
}
Return $r;
}
function addUser($group,$user){
$r = false;
if(isset($this->groups[$group])){
$this->groups[$group]['users'][$user] = 1;
$r = true;
}
Return $r;
}
function delUser($group,$user){
$r = false;
if(isset($this->groups[$group]['users'][$user])){
unset($this->groups[$group]['users'][$user]);
$r = true;
}
Return $r;
}
function dump($file){
$r = false;
if($handle = fopen($file,'w')){
$groups = $this->groups; //get a copy of the groups
array (saves typing :)
//debug
//echo '<pre>';
//print_r($this->groups);
//echo '</pre>';

the users

don't need a comma for the first run
$x++;
}
$gid = $groups[$key]['gid'];
$pass = $groups[$key]['pass'];
$list = $key.':'.$pass.':'.$gid.':'.$userlist."\n"; //
make the entry
fputs($handle,$list); //save it
}
$r = true;
fclose($handle);
}
Return $r;
}
}
//usage
$g = new groupClass('group');
$g ->addGroup('site8');
$g ->addUser('site8','fred');
$g->delUser('site7','tester7');
$g->dump('group2');
