eregi

[Pooptart]

if (!eregi("^([0-9a-z])*$", $username) { $errors = $errors + 'Username not alphanumeric.<br />'; }

Parse error: parse error, unexpected '{' in /home/content/E/l/m/Elmonian/html/lifelessland/register.php on line 14

I dont understand why it is returning an error. Im guesing its because of one of the parentheses or something.

if (!eregi("^([0-9a-z])*$", $username)) { $errors = $errors + 'Username not alphanumeric.<br />'; }

That will display my age, but cause my code to be.. worthless. The rest of the code just doesnt do anything.

This has less to do with eregi() and more to do with your PHP syntax. You are missing a closing parenthesis. It should be:

if (!eregi("^([0-9a-z])*$", $username)) {
    $errors = $errors . 'Username not alphanumeric.<br />';
}

That said, have you considered [man]ctype_alnum/man for this case? Also, the PCRE (preg) regex functions are now generally preferred to the ereg versions these days.

if (!ctype_alnum($username)) {
    $errors .= 'Username not alphanumeric.<br />';
}
