Class Constructor Calls

When calling class constructors with no arguments, always include parentheses:
$foo = new MyClassName();
This is to maintain consistency with constructors that have arguments:
$foo = new MyClassName($arg1, $arg2);
Note :
If the class name is a variable, the variable will be evaluated first to get the class name, and then the
constructor will be called.
Use the same syntax:
$bar = ‘MyClassName’;
$foo = new $bar();
$foo = new $bar($arg1, $arg2);

PHP / SQL Security – The Big Picture

Web Security Whether your site is the web presence for a large multinational, a gallery showing your product range and inviting potential customers to come into the shop, or a personal site exhibiting your holiday photos, web security matters. After the hard work put in to make your site look good and respond to your users, the last thing you want is for a malicious hacker to come along, perform a PHP hack and break it somehow. There are a number of problems in web security, and unfortunately not all of them have definite solutions, but here we'll look at some of the problems that should be considered every time you set out to write a PHP script to avoid a PHP hack attack. These are the problems which, with well-designed code, can be eliminated entirely. Before looking in detail at the solutions, though, lets take a moment to define the problems themselves. SQL Injection In this attack, a user is able to execute SQL queries in your website's database. This attack is u...

PHP / SQL Security – SQL Commands and Non-String Variables

SQL Injection SQL (Structured Query Language) is the language used to interface with many database systems, including MySQL, PostgreSQL and MSSQL. Certain words and characters are interpreted specially by SQL, as commands, separators, or command terminators, for instance. When a user enters data into a form, there is nothing stopping them entering these special commands and characters. Consider the PHP code below: $query = “INSERT INTO orders(address) VALUES('$_GET['address']')”; $result = mysql_query($query); A form with a textbox named address would be used to gather the information for this page. We'll ignore any other form elements for now, but obviously there'd be the order items, a name, possibly a price, a delivery date, and so on, which would also all need storing in a database. Imagine a perfectly legitimate user comes along and enters the following address 14 King's Way Kingston Kingham County The database would spit back an error b...
