PHP中的Restful API？

Question

I want to make restful API in php,i have a file 'index.php' in which php and html code is there,i am trying to make api for it. So please suggest me is it right way to do?

Here is my code:

<?php
$verb=$_SERVER['REQUEST_METHOD'];
if($verb == 'GET')
{
if(isset($_GET['filename'])){
$response = file_get_contents($_GET['filename']);
echo $response;
}
else{
die("ERROR: REQUIRED PARAMETERS NOT GIVEN!");
}
}
?>

Answer 1

First, you have to determine your API endpoints paths and verbs, like:

GET /file/{filename} - will get a file
POST /file - will create a file

Second, you shouldn't use $_GET['filename'] , since your endpoint is for example GET /file/myfile.txt , where filename parameter is myfile.txt and this is a part of the path. So you have to extract parameters from the path.

Third, it's better to use microframework for that purpose.
