if( ereg ("^[[:alpha:]]+$", $username))

Can I do
if( ereg ("^[[:alpha:]]+$", $username, $morevariables))
?


Also I want to use a loop for an array
so
while($info)
{
do stuff
}

I want to use htmlspecialchars and stripslashes to make sure all of the elements in the array info are ok
if they strip+html'ed variables dont match then I want it to say so, can I do this in a simple way? ie not have to write
$check = htmlspecialcharacters($info[0]);
$check = stripslashes($info[0]);
and then compare the original?

Cheers

Ok I was checking the php documention and found a great function for the latter part of my query

array_walk ($array, 'function_name');
It applies a function to every section of the array
