Where is the closing brace for your while loop?

[PHP] Array Elements & While Loops

[Tom Churm]

hi,

my problem is this:  i'm using a while loop to check elements in an
Array for valid email syntax.  if $User[0] is a valid email address but
$User[1] is not, the code for $User[0] is still executed before the die
statement.  i need my loop to finish checking ALL array elements for
validity, and to then die BEFORE any further code is executed.  here's
what i have now (it doesn't work):

//loop to check for bad email addresses:
$j = 0;
$flag = 0;
while ($j < count($User)){
if
(($User[$j]!="")&&!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*$",
$User[$j])) 
{ 
$flag = 1;
$errorNo = $j + 1;
}
//die if flag is 1
if ($flag = 1) {
die ("Email #$errorNo is not a valid e-mail
address!Please return and correct
this."); 
} 
else {
continue...
}

any suggestions would be great!

thanks much,

tom
