Autoload tool for php objects extended by zend api_PHP tutorial

Similar to the autoload function of spl, bloader is an autoload tool for PHP objects, but it is simpler and more efficient, and the configuration is more flexible.

bloader provides a commonly used autoload function ld, and two auxiliary functions, ld_new( Instantiation) and ld_unset (destroy object).

#1 bloader will automatically search for the .class.php file in the current file or current directory, as well as the path defined by the '_MODULES' constant , the instantiated class returns the object.
#2 You can directly use ld('class name') to operate the object (see Example 1-1)
#3 bloader will automatically register a variable with the class name in the current scope The variable '$classname' (see Example 1-2)
#4 Using the ld function in bloader to access objects is globally valid (see Example 1-3)
#5 Use ld_new to instantiate multiple different object without registering variables (see Example 1-4)
#6 Use ld_unset to unregister an instantiated object (see Example 1-5)

Download address: http://code.google .com/p/bloader/downloads/detail?name=bloader.tar.gz

Installation:
phpize
./configure --with-php-config=php-config --enable -bloader
make && make install

Example 1-1

Copy code The code is as follows:

///define('_MODULES',dirname( __FILE__ ).'/class'); ///Optional configuration, search for class files in the specified directory for easy 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
)
)
*/
?>

Copy code 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 global attributes*/
}
}
?>

Example 1-2

Copy code The code is as follows:

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

Example 1-3

Copy code The code is as follows:

ld('users');
printt(); //Print object
...
function printt()
{
var_dump(ld('users'));
}
?>

Example 1-4

Copy code The code is as follows:

$users_1=ld_new('users');
$users_2=ld_new('users');
.. .
?>

Example 1-5

Copy code The code is as follows:

ld('users');
unset_users();
...
function unset_users()
{
ld_unset('users');
}
?>
