[SOLVED] Question about haystack param in ereg and eregi

[jordanwb]

If I pass in an array as seen here:

 

<?php

$username = "some random username";

$username_parts = explode (" ", $username);
if (!eregi("^([0-9a-z])*$", $username_parts)) // Not alphanumeric
{
$this->form_errors++;
}

?>

 

Will that be fine?

According to the docs, no:

 

int eregi  ( string $pattern  , string $string  [, array &$regs  ] )

So for eregi to do what I'd want I'd have to loop through each element and count the number of matches. Then compare that to the number of elements in the array.
