Zendapi extension php object autoload tool_php tutorial

Zendapi extends the php object's autoload tool. Similar to spl's autoload function, bloader is the php object's autoload tool, but it is simpler, more efficient, and more flexible in configuration. bloader provides a common autoload function ld and two auxiliary functions similar to spl's autoload function. bloader is the php object's autoload tool, but it is simpler, more efficient, and more flexible in configuration.

Bloader provides a common autoload function ld and two auxiliary functions, ld_new (instantiation) and ld_unset (destroy object ).

#1 bloader will automatically search for the current file or <类名> The. class. php file, and the path defined by the '_ modules' constant, instantiate the class and return the object.
#2 you can directly use ld ('class name') to operate an object (see instance 1-1)
#3 bloader automatically registers a variable '$ Class name' with the class name in the current scope (see instance 1-2)
#4 use the ld function in the bloader to access objects within the global range (see instance 1-3)
#5 use ld_new to instantiate multiple different objects without registering variables (see instance 1-4)
#6 use ld_unset to deregister an instantiated object (see instance 1-5)

Installation:
Phpize
./Configure -- with-php-config = php-config -- enable-bloader
Make & make install

Instance 1-1

The code is as follows:

/// Define ('_ les', dirname (_ FILE __). '/class'); // optional configuration. you can search for class files in the specified directory to facilitate instantiation.
Ld ('C1 ', array ('1', '2')-> a1 = "a1"; // parameter 2 is the parameter of the constructor.
Ld ('C1 ')-> a2 = 'A2 ';
Ld ('C1 ')-> printt ();

/**
Show:
C1 Object
(
[A1] => a1
[A2] => a2
[A3] => Array
(
[0] => 1
[1] => 2
)
)
*/
?>

The code is as follows:

/**
Example:
./Class/c1.class. php:
*/
Class c1
{
Public $ a1 = 123;
Public $ a2 = 'abc ';
Public $ a3 = 100;
Public function _ construct ($ ls)
{
$ This-> a3 = $ ls;
}
Public function printt ()
{
Print_r (ld ('C1 ');/** use the global feature */
}
}
?>

Instance 1-2

The code is as follows:

...
Ld ('users ');
// The $ users variable is automatically registered.
$ Users-> method ();
....
?>

Instance 1-3

The code is as follows:

Ld ('users ');
Printt (); // Print the object
...
Function printt ()
{
Var_dump (ld ('users '));
}
?>

Instance 1-4

The code is as follows:

$ Users_1 = ld_new ('users ');
$ Users_2 = ld_new ('users ');
...
?>

Instance 1-5

The code is as follows:

Ld ('users ');
Unset_users ();
...
Function unset_users ()
{
Ld_unset ('users ');
}
?>
