Let's talk about the automatic loading of classes in PHP. Many do not know that it is generally there, although this opportunity appeared in the first versions of PHP 5 and it is called __autolaoad ().

This magic feature is intended to save us from endless Include and Require in the site code. The function is called each time during the creation of an object or access to the class instance. But this method has a number of shortcomings, namely:
- After declaring this function, it is not possible to deactivate it or modify
- You can not declare several different bootloaders.

To solve these problems in PHP 5.1.2, a number of SPL functions appeared.

• sPL_AUTOLOAD_CALL - forcibly loads the class by his name using all autoloader available in the system;
• sPL_AUTOLOAD_EXTENSIONS - Returns / Modifies File Extensions from which uninitialized classes is loaded;
• sPL_AUTOLOAD_FUNCTIONS - Returns a list of all registered autoloaders in the system;
• sPL_AUTOLOAD_REGISTER - Registration of your own autoloader in the stack of autoload;
• sPL_AUTOLOAD_UNREGISTER - removal of the autoloader from the startup stack;
• sPL_AUTOLOAD is the main function of automatic classes. It is she called when accessing the class, which is not yet initialized. This feature activates all the automatic loaders from the stack in order to add them.

Immediately need to clarify what is the stack of autoload functions. This is an array, the elements of which are autoloaders. The order of autoloaders corresponds to the order of their registration, using SPL_AUTOLOAD_REGISTER. If you declared the __autoload () function before calling the SPL_AUTOLOAD_REGISTER, it will be removed from the startup stack.

To declare the autoloader as follows:

fUNCTION AUTOLOADER ($ CLASS) (
require_ONCE
}
sPL_AUTOLOAD_REGISTER ("AutoLoader");

Either, starting with PHP 5.3.0 using nameless functions
sPL_AUTOLOAD_REGISTER (FUNCTION ($ Class) (
require_ONCE "Classes /". $ class. ".php";
});

For example, if two autoloaders are registered:

sPL_AUTOLOAD_REGISTER ("AutoFader2");

The sequence of accessing them during the class call will be as follows:
autoLoader1 ($ Class)
autoLoader2 ($ Class)

In PHP 5.3.0, several very useful opportunities for working with autoloaders have been added.
1. The third parameter of the function SPL_AUTOLOAD_REGISTER () - $ prepende.It allows you to move the new-added autoloader to the beginning of the download stack. I.e:

sPL_AUTOLOAD_REGISTER ("AUTOLOADER1");
sPL_AUTOLOAD_REGISTER ("AutoLoader2", True, True);

Will lead to the fact that the order of calling the autoloader to the following will be changed:
autoLoader2 ($ Class)
autoLoader1 ($ Class)

2. Working with Namespace as a tract for the location of the class. For instance:

include_ONCE $ Class. "PHP";
}
sPL_AUTOLOAD_REGISTER ("AUTOLOADER1");
uset.eST.\ s.ySTEMS \\u.ser asu.sER;
$ usr \u003d newu.ser ();

Will attempt to connect the class on the waytest / Systems / Users.php

But be careful when using such a method for connecting classes. For an unknown reason, when convertingnamespace.add to the location of the class you need, the path is shown to the lower register. As a resultt.eST \\S.ySTEMS \\U.ser.will transformed B.t.eST /s.ySTEMS /u.ser.If the location on the file system of the file you look liket.eST /S.ySTEMS /U.sEROS will not find the desired file, because* NIX C.perfect to the register in the file system.

Sometimes it uses a class map for autoload. The most simple class of the class can be considered an associative array, as a key in which the name of the class is indicated, and the value corresponds to the path to it.

For example:
$ Classmap \u003d Array (
"Class1" \u003d\u003e "System / Site /",
"ClassS2" \u003d\u003e "User / Lib /",
);

For flexibility, it is advisable to carry out the classes map in a separate file. This will make it possible to generate it with additional software, or notice, at the test stage. This can be done for example:

function AutoLoader1 ($ Class) (
include_once "classmap.php";
include_ONCE $ Classmap [$ Class].$ Class. ".php.”;
}

Today is a light, but useful article - determining the vehicle speed. In our age of information technologies, digital radars and digital cameras, you need to know exactly the speed of your car. Moreover, almost every car does not show exact speed, there are cases when the car speedometer is lying by 5 or more kilometers per hour. Why need to determine the exact reading? Everything is simple, now even exceeding a couple of kilometers fixed radars, especially for five and higher ...

A simple example is your car moving at a speed of 73 km / h, that is, it already falls under the penalty, as the excess of more than 10 km / h. But if your speedometer is lying and exceeds the speed of 5 to 7 km / h, then the speed of 66 is 68 km / h and you still do not exceed it. Therefore, it is necessary to clearly know how lying your speedometer is useful for the future.

So, I will define the speed of my car ().

I accelerate the car to a speed of 90 km / h and turn on, the car moves at a speed of 90 km / h. That is, I do not break anything, 90 km / h is the normal speed for country tracks. But is it really my car moving at this speed? It is necessary to determine the exact vehicle speed.

In this we will help all the same "old - kind". The thing is that Navitel measures the real vehicle speed, leads us on satellites, so it can not lie almost.

In the upper corner of the screen, the real vehicle speed is displayed, the Navitel is checked by this speed with satellites.

As you can see, the car is steadily moving at a speed of 90 km / h, and Navitel shows 86 - 87 km / h, the speed jumps a little.

Thus, my car overslets the speed of 3-4 km / h, and this is essential. That is, if I am an engine at a speed of 103 km / h, outside the city, I will not break anything to break, there will be no exceeds 10 km / h.

Now a small video how to determine the speed of the car.

Car speed video

The speed on Toyota Camry was measured at one comrade, in the old body, so there is at all the difference in speed of 7 - 8 km / h, in a large strand.

Something like this, I hope today's easy article will help you. Guys Know your real speed, it is really necessary information.

That's all, read our car site.
