  1. I created various websites (based on Larry's code) that worked fine for years, but after my web hosting company upgraded to PHP Version 5.6.27, I repeatedly receive this error message: "An error occurred in script '.../mysql_connect.php' on line 8: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead" I was able to suppress that error message on one website by prepending the "@" symbol to the expression, but strangely it did not work on another site. I'd like to know why (as a quick fix), and whether I can do something to suppress error messages for an entire site instead of using "@" multiple times. I'd also love to know how to change my code to work with PDO (preferably) or MySQLi; my web host supports both. It would be great to see an example of PHP handling data with old MySQL code and PHP working with PDO or MySQLi, to see how to "translate" it, so to speak. However, I don't want to use PDO if that requires me to learn Object-Oriented PHP; all my sites are based on procedural PHP. The above error message is generated in response to this mysql_connect.php code: <?php error_reporting(0); // didn't suppress error message ini_set('display_errors',0); // didn't suppress error message DEFINE ('DB_USER', '***'); DEFINE ('DB_PASSWORD', '***'); DEFINE ('DB_HOST', '***'); DEFINE ('DB_NAME', '***'); if ($dbc = @mysql_connect (DB_HOST, DB_USER, DB_PASSWORD)) { // this is the line generating the error message if (@!mysql_select_db (DB_NAME)) { trigger_error("Could not select the database!\n<br />MySQL Error: " . mysql_error()); exit(); } } else { trigger_error("Could not connect to MySQL!\n<br />MySQL Error: " . mysql_error()); exit(); } function escape_data ($data) { if (ini_get('magic_quotes_gpc')) { $data = stripslashes($data); } if (function_exists('mysql_real_escape_string')) { global $dbc; $data = @mysql_real_escape_string (trim($data), $dbc); } else { $data = @mysql_escape_string (trim($data)); } return $data; } ?> Thank you!
  2. Hello. I just read the AJAX chapter in PHP and MySQL and want to learn much more on the topic--especially concerning PHP's role with AJAX. I'm seriously considering buying the AJAX: Visual QuickProject book, but noticed it was published a while ago. I'm wondering about both what deprecated features (in PHP and Javascript) might be present in the book and whether I should start with the Javascript book. Please kindly advise. Thank you!
