This article introduces an original article about discuz X single-piece mode. The PPC highlight plug-in is too unfriendly. It may be strange to paste txt content directly.
As long as there is such a sentence at the beginning of the file
| The Code is as follows: |
Copy code |
$ Discuz = & discuz_core: instance ();
[Code language = php] // Instance () belongs to the discuz_core class in class_core.php
Function & instance (){
Static $ object;
If (empty ($ object )){
$ Object = new discuz_core ();
}
Return $ object;
}
[/Code]
Make sure that a discuz_core instance is used for all word requests. Here, & is written to be compatible with PHP4. If it is in PHP5, you can use static.
[Code language = php]
// Here is a simple example of the single-piece mode.
Class PHPig {
Private static $ v = null;
Static function instance (){
If (self: $ v = null ){
Self: $ v = new PHPig ();
}
Return self: $ v;
}
}
$ Pig1 = PHPig: instance ();
$ Pig2 = PHPig: instance ();
If ($ pig1 ===$ pig2 ){
Echo 'same object ';
} Else {
Echo 'not the same object ';
}
[/Code] |
