Detailed explanation of the implementation method of pseudo-static php url

//Convert url to static url
function url_rewrite($file, $params = array (), $html = "", $rewrite = true) {

 if ($rewrite) { //Do not rewrite during the development stage. During development, set $rewrite = false
 $url = ($file == 'index') ? '' : '/' . $file;
 if (! empty ( $params ) && is_array ( $params )) {
 $url .= '/' . implode ( '/', array_slice($params, 0 , 2));
 $param = array_slice($params , 2);
 foreach($param as $key => $value){
 $url .= '/' . $key . '/' . urlencode ( $value );
 }
 }
 if (! empty ( $html )) {
 $url .= '.' . $html;
 }
 } else {
 $url = ($file == 'index') ? '/' : '/' . $file;

 if (substr ( $url, - 4 ) != '.php' && $file != 'index') {
 $url .= '.php';
 }

 if (! empty ( $params ) && is_array ( $params )) {
 $url .= '?' . http_build_query ( $params );
 }
 }
 return $url;
}

echo url_rewrite ( 'test', array ('class' => "User", 'act' => 'check', 'name' => 'tank','page'=>5 ) );echo "";
//$rewrite = In the case of false, the display is as follows/test.php?class=User&act=check&name=tank
echo url_rewrite ( 'test.php', array ('class' => "User", 'act' => 'check', 'name' => 'tank' ) );echo "";
//When $rewrite = true, the display is as follows/test.php/ User/check/tank

echo url_rewrite ( 'test', array ('class' => "User", 'act' => 'check', 'name' => 'tank' ) );echo " ";
//When $rewrite = true, the following is displayed/test/User/check/tank
echo url_rewrite ( 'test', array ('class ' => "User", 'act' => 'check', 'name' => 'tank' ), 'html' );echo "";
//$rewrite = If true, the display is as follows /test/User/check/tank.html
?>

"User",'act'=>'check','name '=>'tank'));?>">test

The above converts the dynamic URL into a static URL, and the link will be generated on the page as follows: test If you click directly at this time, a 404 error will definitely be reported, because it is impossible to find the tank directory. You need to specify a php file for the directories and files that cannot be found. This requires the use of apache, nginx, or htaccess, etc.

Three, designate a unified entrance

RewriteCond %{REQUEST_FILENAME} !-f //File not found
RewriteCond %{REQUEST_FILENAME} !-d //Cannot find directory
RewriteRule . /test3/index.php [L]

Code description: If the directory is not found, go to the index.php file. If the file is not found, also go to index.php. When accessing http://localhost/test3/test.php/User/check/tank, it will go to index.php. The following content is operated by rewriting http://localhost/test3/test.php/User/check/tank.

Four, index.php file

$filename = $_SERVER['REQUEST_URI']; //Requested url

/**Requested url, "/test3/test.php/User/check/tank"
 * test.php is the php file to go to
 * User is the class name
 * check is the method name in the class
 * tank is to be passed to Check parameters
* by bbs.it-home.org
*/

preg_match("/(w+.php)/" ,$filename,$match); //Find the php file name

$array = explode('/',$filename); //Split the static url

$key = array_keys($array,$match[0 ]); //Get the subscript Array corresponding to the file ( [0] => 2 )
$file_array = array_slice($array,0,$key[0]+1); //Array ( [0] = > [1] => test3 [2] => test.php )
$param_array = array_slice($array,$key[0]+1); //Array ( [0] => User [1 ] => check [2] => tank )

$file_path = implode('/',$file_array);

if($array[$key[0]] != "index.php"){
 include_once($array[$key[0]]); //Include the php file in the request url, here it is test.php
}

if(class_exists($param_array[0])){ //Judge Check if there is a class User in the file test.php

 $obj = new $param_array[0];
 if(method_exists($obj,$param_array[1])){ //Check if there is a class User There is no check method
 $obj->$param_array[1]($param_array[3]); //Call this method, the result is (my name is tank)
 }
}
?>

5, test.php file

class User {
 public function check($name){
 echo "My name is".$name;
 }
}
?>

At this point, when accessing http://localhost/test3/test.php/User/check/tank, no error will be reported.
