Build Your own Database Driven Web Site Using PHP & MySQL is a practical hands-on guide to learning all the tools, principles and techniques needed to build a fully functional database-driven web site using PHP & MySQL.
This book covers everything from installing PHP & MySQL under Windows, Linux, and Mac through to building a live web-based content management system.
While this is essentially a beginners book, it also covers more advanced topics such as the storage of binary data in MySQL, and cookies and sessions in PHP. It comes complete with a set of handy reference guides for PHP & MySQL that include:
The Principles of Beautiful Web Design (2nd Edition)
Pro HTML5 Programming: Powerful APIs for Richer Internet Application Development

called $_GET. But where does the $_GET array come from? It turns out that $_GET is one of a number of variables that PHP automatically creates when it receives a request from a browser. PHP creates $_GET as an array variable that contains any values passed in the query string. $_GET is an associative array, so the value of the name variable passed in the query string can be accessed as $_GET['name']. Your welcome1.php script assigns this value to an ordinary PHP variable ($name), then displays it
generated page without question. If the code is as innocuous as a tag there’s no problem, but a malicious user could include sophisticated JavaScript code that performed malicious actions like steal the user’s password. All the attacker would have to do, then, would be to publish the modified link on some other site under the attacker’s control, and then entice one of your users to click it. The attacker could even embed the link in an email and send it to your users. If one of your users
has a value of false (that is, when the connection attempt has failed). If the connection succeeds, $link will have a value that’s considered true, which will make !$link false. In short, the body of the if statement is executed only if the connection fails. Within the body of the if statement, we set the variable $output to contain a message about what went wrong. We then include the template output.html.php. This is a generic template that simply outputs the value of the $output variable:
a call to mysqli_query for each and every joke to be displayed. This would be messy and slow. As your database of jokes increased in size, the overhead of all those queries would drag down the performance of your site in a big way. With all this taken into account, it would seem that the “old way” was actually the better solution, despite its weaknesses. Fortunately, relational databases like MySQL Relational Database Design are designed to make it easy to work with data stored in multiple
