note 48673 added to function.getmxrr

This code replicates online tools that let you check if an email address is valid. First it checks if the email format is correct, then looks up and prints the mx records. All nicely formatted with fancy words that in the end prints whether the email address valid or invalid. <?php $email = "email@domain.com"; print("Checking: $email<br>"); if (eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)+$", $email)) { print("Format Test: PASSED<br>"); print("Online host verification Test...<br><br>"); print("MX Records for: $email<br>"); list($alias, $domain) = split("@", $email); if (checkdnsrr($domain, "MX")) { getmxrr($domain, $mxhosts); foreach($mxhosts as $mxKey => $mxValue){ print("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$mxValue<br>"); } print("Online host verification Test: PASSED<br><br>"); print("Email Status: VALID"); } else { print("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;No records found.<br>"); print("Online host verification Test: FAILED<br><br>"); print("Email Status: INVALID"); } } else { print("Format Test: FAILED<br><br>"); print("Invalid email address provided.<br><br>"); print("Email Status: INVALID"); } ?> ---- Manual Page -- http://www.php.net/manual/en/function.getmxrr.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48673 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48673&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48673&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48673&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48673&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48673&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48673&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48673&report=yes Search -- http://master.php.net/manage/user-notes.php
