Code for create php simple rest api example and demo

// hear we get the HTTP method, path and body of request
$request_method = $_SERVER['REQUEST_METHOD'];
$request_data = explode('/', trim($_SERVER['PATH_INFO'],'/'));
$get_input = json_decode(file_get_contents('php://input'),true);
// hear mysql database connect
$connect_link = mysqli_connect('localhost', 'root-user', 'password', 'onlinecode-db');
// hear retrieve the table and key from the path
$table_name = preg_replace('/[^a-z0-9_]+/i','',array_shift($request_data));
$set_key = array_shift($request_data)+0;
// hear escape the columns and values from the input object

$columns_val = preg_replace('/[^a-z0-9_]+/i','',array_keys($get_input));
$input_values = array_map(function ($get_value) use ($connect_link) 
  if ($get_value===null) return null;
  return mysqli_real_escape_string($connect_link,(string)$get_value);
// hear build the SET part of the SQL command
$set = '';
for ($i=0;$i<count($columns_val);$i++) 
// hear create SQL based on HTTP request_method
switch ($request_method)

how to Run this php smiple rest api example and demo

Save this file as “api.php” in your (Apache) document root and decision it using:


Or you will use the PHP intrinsic webserver from the statement using:

$ php -S localhost:8888 api.php

The URL once ran in from the statement is:{$table}/{$id}

NB: Don’t forget to regulate the ‘mysqli_connect’ parameters within the on top of script!

REST API during a single PHP file

Although the on top of code isn’t good it really will do three vital things:

  • Support HTTP verbs GET, POST, UPDATE and DELETE
  • Escape all knowledge properly to avoid SQL injection
  • Handle null values correctly

One might so say that the remainder API is absolutely useful. you will run into missing options of the code, such as:

  • No permission system
  • No column choice supported
  • No connected knowledge (automatic joins) supported
  • No page number or sorting supported
  • No condensed JSON output supported
  • No search/filter support
  • No support for PostgreSQL or SQL Server
  • No base64 binary column support
  • No POST parameter support
  • No JSONP/CORS cross domain support
