API Functions in file api.php
<?php

/*

*/
private function dbConnect(){
$this->db = mysql_pconnect(self::DB_SERVER,self::DB_USER,self::DB_PASSWORD);
if (!$this->db)
{
echo "Please try later.";
}
if($this->db)
mysql_select_db(self::DB,$this->db);
}
/*

* This method dynmically call the method based on the query string
*
*/
public function processApi(){
$func = strtolower(trim(str_replace("/","",$_REQUEST['rquest'])));
if((int)method_exists($this,$func) > 0)
$this->$func();
else
$this->response('',400); // If the method not exist with in this class, response would be "Page not found".
}
/*************API SPACE START*******************/
private function about(){
if($this->get_request_method() != "POST"){
$error = array('status' => 'WRONG_CALL', "msg" => "The type of call cannot be accepted by our servers.");
$error = $this->json($error);
$this->response($error,406);
}
$data = array('version' => '0.1', 'desc' => 'This API is created by Blovia Technologies Pvt. Ltd., for the public usage for accessing data about vehicles.');
$data = $this->json($data);
$this->response($data,200);

/*************API SPACE END*********************/
/*

private function json($data){
if(is_array($data)){
return json_encode($data, JSON_PRETTY_PRINT);
}
}

// Initiiate Library
$api = new API;
$api->processApi();
?>
Now finally configure .htaccess
Create a file named .htaccess in the same folder where you place api.php and Rest.inc.php
RewriteBase /
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-s
RewriteRule ^(.*)$ api.php?rquest=$1 [QSA,NC,L]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.*)$ api.php [QSA,NC,L]
RewriteCond %{REQUEST_FILENAME} -s
RewriteRule ^(.*)$ api.php [QSA,NC,L]
Now call your API like
localhost/about
where about is the function. You can dynamically check whether it is GET or POST inside the function, and send response text and codes as required. I have given you entirely what you want.
Considering api.php and Rest.inc.php are both in /, (that is what in RewriteBase in .htaccess file)
If you want to place the files in some other directory or folder, for example /beta/v1/
Change the RewriteBase from / to /beta/v1
Note. Place the .htaccess in the same folder.
And both the files in the same directory. The directory should be placed in the htaccess in RewriteBase
If you have any issues understanding the above, let me know.
