Php post request issue

[tango4567]

Why I'm getting empty array all the time. Please suggest me whats wrong in this below code:

<?php
function validateEmail($checkEmail){
    return filter_var($checkEmail, FILTER_VALIDATE_EMAIL);
}

$email = isset($_POST["emails"]) && is_array($_POST["emails"]) ? $_POST["emails"] : [];
$validateEmail = 'validateEmail';
$sorted_emails = array_filter($email, $validateEmail);

header("Content-Type: application/json");
echo json_encode($sorted_emails);
?>

Basically after doing some studies with help of $_POST and PHP Cookbook then i realized my sily mistake, if we use $_POST in index.php then we need to define full path including index.php then on $_POST variable work other wise it always return empty as mentioned in above problem. So I just gave path. :heavy_multiplication_x: https://tarunmahajan.com/api/email :heavy_check_mark: https://tarunmahajan.com/api/email/index.php

I hope this will help and I request you if found any mistake with this explantion please correct me Thank you.
