Email validation help...please

[Anon]

I am just starting out in the PHP journey and I have run into a problem with something very simple. An email validation. My code is from zend and should work ok:
function is_valid_email_eregi ($address) {

    return (eregi(
        '^{[-!#$%&\'*+\./0-9=?A-Z_`{|}~]+'.      // the user name}
        '@'.                                      // the ubiquitous at-sign
        '([-0-9A-Z]+.)+' .                       // host, sub-, and domain names
        '([0-9A-Z]){2,4}$',                       // top-level domain (TLD)
        trim($address)));
}
but I get a parse error no matter where I put this code (I have tried in the form page and in it's own page using require on my form) and the parse error occurs on the first line of this code.....is there something im missing? This has really got me bugged......

Hi, I just use this code, it works very nicely:

function verifyemail($testemail) {
if (strlen($testemail) < 3) { return false; } // MAKE SURE EMAIL IS AT LEAST 3 CHARACTERS
if (strpos($testemail,"@") == "") { return false; } // MAKE SURE @ IS PRESENT
if (substr($testemail,0,1) == "@") { return false; } // MAKE SURE FIRST CHARACTER IS NOT @
if (substr($testemail,-1) == "@") { return false; } // MAKE SURE LAST CHARACTER IS NOT @
if (substr_count($testemail,"@") > 1) { return false; } // MAKE SURE THERE IS ONLY 1 @
if ($sent_emailaddr != $verifiedemailaddr) { return false; } // MAKE SURE THAT THE TWO EMAIL ADDRESS ARE THE SAME
return true;
}

Enjoy!!

here is one short one:
