Solution 1 :

this will work try getting data with file_get_contents('php://input') instead of using $_POST

i tried it with you code and it works

$value = file_get_contents('php://input');
$value = json_decode($value);
$phone = $value->{"phone_num"};
echo $phone;

I think this is a better approach


const response = fetch('http://localhost:8888/project/my-script.php', {
        method: 'POST', // *GET, POST, PUT, DELETE, etc.
        headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        body: new URLSearchParams({phone_num: 12345678}).toString()


 $request_method = $_SERVER['REQUEST_METHOD'];
    if ( $request_method == 'POST' ){
          echo "This is working!!";
    }else {
          echo json_encode('No defined function for this method');

Solution 2 :

Try using $_REQUEST instead of $_GET.

I know it is lame to use that. But even with ReactJS also, I am facing the same issue and I resolved it with this.

Solution 3 :"POST", "http://localhost:8888/project/my-script.php", true);

In your above url it seems that you are sending a post request

$request_method = $_SERVER['REQUEST_METHOD'];
if ( $request_method == 'POST' ){
      echo "This is working!!";
      echo $_GET['phone_num'];
}else {
      echo json_encode('No defined function for this method');

And if your php function it seems that you are accessing the variable phone_num using the GLOBAL GET array.

Change it to post


Solution 4 :

use this

echo $_POST[‘phone_num’];

Instead of

echo $_GET[‘phone_num’];

Problem :

I have been trying to post data to my PHP script, which works fine for POSTMAN, shows the results correctly. But in while sending the data using AJAX in my html project, the data is not being sent/accepted by the PHP script, hence no show data.

Possible Problem: JSON data type is not working for PHP script, since param is not getting read by $_POST['phone_num']

HTML Code:

<!DOCTYPE html>

<h2>The XMLHttpRequest Object</h2>

<button type="button" onclick="loadDoc()">Request data</button>

<p id="demo"></p>

  function loadDoc() {
    var xhttp = new XMLHttpRequest();
    xhttp.onreadystatechange = function() {
      if (this.readyState == 4 && this.status == 200) {
        document.getElementById("demo").innerHTML = this.responseText;
    };"POST", "http://localhost:8888/project/my-script.php", true);
    xhttp.setRequestHeader("Content-type", "application/json");
    xhttp.send('{ "phone_num" : "12345678" }');


PHP Script:

$request_method = $_SERVER['REQUEST_METHOD'];
if ( $request_method == 'POST' ){
      echo "This is working!!";
      echo $_GET['phone_num'];
}else {
      echo json_encode('No defined function for this method');


Result: I get This is working!!, but no phone_num which I passed through this code via AJAX

Observation: There is a catch, if we use $_POST['phone_num'] in place of $_GET['phone_num'], then the POSTMAN also doesn’t return any data except This is working!!.

Please help where I am going wrong. That’d be great. Thanks.

To check, if things working fine or not. It won’t make a difference, right?

You send “phone_num” trough a POST request, in PHP you can fetch that variable then with $_POST[“phone_num”] instead of $_GET, with the $_get you can read variables from the url

No wont fix it, but a waste of cpu cycles and memory 🙂

echo $_POST['phone_num'];

One question, why this doesn’t work in POSTMAN? It doesn’t show up any output, it worked on HTML now. I will mark your answer, just wanted to ask this question.
