Modern PHP
Generators
Generators are similar to iterators that calculate their values on demand, thus potentially using fewer resources. They can be created using the yield keyword, e.g.:
function my_generator()
{
yield 1;
yield 2;
yield 3;
}
Generators are forward-only iterators, i.e. you can only request the next value, not the previous, next but one etc. They are useful for iterating sequential data sets such as reading a file line by line (in order).
Autoloading
The original mechanism for autoloading was the magic function __autoload(). This is no longer recommended and is deprecated in PHP 7.x.
The successor to __autoload() is spl_autoload_register(). This in turn has been replaced by PSR-0, then PSR-4. Composer will generate a PSR-4 autoloader for you.
Built-in web server
PHP comes with a built-in web server which is useful for development purposes, although it should never be used in production.
- Configuration directives:
-c config/php.ini
Useful dependencies
- FastRoute
