A way to implement the global static variable class in PHP

variables | static

The following is a global static variable class in which the functions inside a class are static functions.

Notice inside the symbol "&" that he used to address the reference. If you are unfamiliar with the way you refer to it, refer to the relevant chapters in the PHP manual.

In addition, this example is modeled on PHP's Pear class Library, pear.php in the static global error method to achieve.

?
Class statvar{
function &setinit () {
static $static = ';
return $static;
}
function set ($key, $value) {
$var = &statvar::setinit ();
$var [$key] = $value;
}
function &get ($key) {
$var = &statvar::setinit ();
return $var [$key];
}
}
Examples are as follows:
Statvar::set (' AA ', ' BB ');
echo statvar::get (' AA ');
?>
