note 86862 added to function.fsockopen

Here is a slightly revised version of the USPS zip code city finder that includes some error messages, as well as changed the $_GET['zip5'] variable into an easier to remember $_GET['zip'] variable: <?php if($_GET['zip']) { if(!($fp = fsockopen('zip4.usps.com', 80, $errno, $errstr))) echo 'Could not connect to USPS! Error number: ' . $errno . '(' . $errstr . ')'; else { $poststring = "GET /zip4/zcl_3_results.jsp?zip5=" . $_GET['zip'] . " HTTP/1.0\r\n" . "Connection: close\r\n\r\n"; fputs($fp, $poststring); $buffer = ''; while(!feof($fp)) $buffer .= fgets($fp, 128); fclose($fp); preg_match('/Actual City name(.*)/s', $buffer, $match); $temp = explode('Not Acceptable', $match[1]); // Capture city/state combination for all valid cities preg_match_all('/headers="pre">(?:<b>)?([\w|\s]+), (\w+)/', $temp[0], $acceptable, PREG_SET_ORDER); $values = array(); foreach($acceptable as $value) $values[] = array ( 'city' => $value[1], 'state' => $value[2] ); if(count($values) == 0) echo 'Zip could not be found in the database!'; } } else echo 'Please specify a zip!'; ?> ---- Server IP: 209.41.74.194 Probable Submitter: 67.214.241.189 ---- Manual Page -- http://www.php.net/manual/en/function.fsockopen.php Edit -- https://master.php.net/note/edit/86862 Del: integrated -- https://master.php.net/note/delete/86862/integrated Del: useless -- https://master.php.net/note/delete/86862/useless Del: bad code -- https://master.php.net/note/delete/86862/bad+code Del: spam -- https://master.php.net/note/delete/86862/spam Del: non-english -- https://master.php.net/note/delete/86862/non-english Del: in docs -- https://master.php.net/note/delete/86862/in+docs Del: other reasons-- https://master.php.net/note/delete/86862 Reject -- https://master.php.net/note/reject/86862 Search -- https://master.php.net/manage/user-notes.php
