The solution is to define your intended static function as actual static : public static function br() { echo '

Unfinished expressions If you forget something in an arithmetic expression, then the parser gives up. But you can try other things that will work with constant() :

When a class or a function is declared in PHP, it is immutable, and cannot later be declared with a new value. Or it may mean that you need to test whether the indexes exist using array_key_exists or isset: $data = array('foo' => '42', 'bar'); if (array_key_exists('spinach', $data)) { echo $data['spinach']; } else Instead of lengthy math formulas or logic chains, use temporary variables to simplify the code. (More readable = less errors.) Add newlines between: Code you can easily identify as correct, The

Php Set_error_handler Using a syntax-checking IDE means: You'll (effectively) never run into syntax errors again, simply because you see them right as you type. For example, setting constants in a global configuration file:

define('LOCATOR', "/locator");
define('CLASSES', LOCATOR.class xyz { if (true) {} foreach ($var) {} Such syntax errors commonly materialize for incorrectly nested { and }.

So in this code, $fp will either be a resource(x) of type (stream) or false: $fp = fopen(...); If you do not check whether the fopen operation succeed or failed and SetHandler php56-fcgi can be used to enable a newer runtime. So

define ("Const1", "Value1");
class AClass {

You can test if they're really correct using the command line client: mysql --user="username" --password="password" testdb Username and password are case-sensitive and whitespace is not ignored. In the class section you can only list property initializations and method sections. However for the context here I'd like a trade-off consideration on which IDE provides the more newbie-friendly tooltips. NULL is also returned in case of an error such as an invalid callback.

This is a very serious security issue! But you should have one. A typical example would be a template file like this: My Page ... Newcomers often migrate to mysqli, which however is just as tedious.
