The AutoLoad function, like SPL, bloader the AutoLoad tool for PHP objects, but is simpler and more efficient and more flexible to configure.
Bloader provides a common autoload function, LD, and two auxiliary functions, ld_new (instantiation) and Ld_unset (destroying objects).
#1 Bloader will automatically search for the current file or the current directory <类名> The. class.php file, along with the path defined by the ' _modules ' constant, instantiates the class to return the object.
#2 can manipulate objects directly using LD (' Class name ') (see example 1-1)
#3 Bloader will automatically register a variable ' $ class name ' with the class name as the variable name in the current scope (see example 1-2)
Accessing an object using the LD function #4 Bloader is globally valid (see Example 1-3)
#5 instantiate multiple different objects with ld_new without registering the variables (see example 1-4)
#6 unregister an already instantiated object using Ld_unset (see example 1-5)

Installation:
Phpize
./configure--with-php-config=php-config--enable-bloader
Make && make install
Example 1-1
Copy CodeThe code is as follows:
Define (' _modules ', DirName (__file__). ' /class '); Optional configuration to find the class file under 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 CodeThe code is as follows:
/**
Example
./class/c1.class.php:
*/
Class C1
{
Public $a 1=123;
Public $a 2= ' abc ';
Public $a 3=100;
Public function __construct ($LS)
{
$this->a3= $ls;
}
Public Function Printt ()
{
Print_r (LD (' C1 ')); /** uses the global feature */
}
}
?>
Example 1-2
Copy CodeThe code is as follows:
...
LD (' users ');
$users variables are automatically registered
$users->method ();
....
?>
Example 1-3
Copy CodeThe code is as follows:
LD (' users ');
Printt (); Print objects
...
function Printt ()
{
Var_dump (LD (' users '));
}
?>
Example 1-4
Copy CodeThe code is as follows:
$users _1=ld_new (' users ');
$users _2=ld_new (' users ');
...
?>
Example 1-5
Copy CodeThe code is as follows:
LD (' users ');
Unset_users ();
...
function Unset_users ()
{
Ld_unset (' users ');
}
