A super simple method to implement pseudo url under PHP [Transfer]_PHP Tutorial
Just like the address path in my log, let index.php?action=one&do=two
become: ?index/action/one/do/two
index.php
--------------
// PARSING QUERY STRING
$QS=explode("&",$_SERVER['QUERY_STRING']);
$QS=explode('/',$QS[0]);
// IF Modul is Undefined set it to index
if (!$QS[0]) $MODUL='index';
else $MODUL=strtolower($QS[0]);
// WE can make a Variable $_QUERY
// for alternative _GET
for ($i=1;$i
$_QUERY[$NVAR]=$NVAR=$QS[$i];
$$NVAR=$QS[$i+1];
}
// Check the Modul is exists?
if (!file_exists("modul_directory/{ $MODUL }.php"))
$MODUL="index";
####THIS IS EXAMPLE TO IMPLEMENTATION THE SCRIPT
// Load The Template
include("template.php");
// Load The Module
include("modul_directory/{ $MODUL }.php");
// Load The Footer
include("footer.php");
?>
we can access the modul in URL like this:
======= ==========================
www.example.com/?forum/topic/20
- it means load the modul forum.php, and set the _QUERY['topic']=20
www.foo.com/?voting/id/54/type/piechart&choice=2
- it mean load the modul voting.php, and set the _QUERY['id']=54 and _QUERY['type']='piechart' and set _GET['choice']=2

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
