unable to send base64 image more than 100kb

Question

I am trying to send a base64 based data that is an png to PHP based script where i am unable to upload image more than 100kb below 100kb images are sending.

script is working fine on WAMP Server the problem is only on live server

here is that Javascript code which I am using to send data

var canvas = document.getElementById("myCanvas");
    var ctx = canvas.getContext("2d");
    var img = document.getElementById("image");
   ctx.drawImage(img, 10, 10);
       
function uploadimg(){
var canvas = document.getElementById('myCanvas');
    var image = canvas.toDataURL();
    var request = new XMLHttpRequest();
    var fd = new FormData();
    fd.append('picture', image);
    request.open('POST', 'upload.php');
    request.onload = function () {
        if (request.status == 200) {
            console.log('all done: ');
            
        } else {
            console.log('Nope');
        }
    };
    request.send(fd);
}

here is upload.php code

 define('IMAGE_DIR', 'image/');
 $img = $_POST['picture'];
 $img = str_replace('data:image/png;base64,', '', $img);
 $img = str_replace(' ', '+', $img);
 $data = base64_decode($img);
 $file = IMAGE_DIR . uniqid() . '.png';
 $success = file_put_contents($file, $data);

What is the value of attribute `post_max_size` in the `php.ini` on your live server? — Evgeniy, Sep 01 '20 at 06:45

What is your console output when you upload image over 100kb ? — shujat132, Sep 01 '20 at 06:55
Does this answer your question? [Change the maximum upload file size](https://stackoverflow.com/questions/2184513/change-the-maximum-upload-file-size) — Manish, Sep 01 '20 at 06:59
@Evgeniy `post_max_size` is 512MB and upload_max_filesize = 512MB — asimdev, Sep 01 '20 at 07:15
If you getting `500` code you need to look at the `apache` error logs. The error is references to `PHP` — Evgeniy, Sep 01 '20 at 08:21
@asimdev can you write die('test'); before define('IMAGE_DIR', 'image/'); and try to submit form and please past here console out put again — shujat132, Sep 01 '20 at 08:36
@asimdev Its mean there is no problem with uploading of image of over 100kb, rather some there is some error on your php code. — shujat132, Sep 02 '20 at 06:02
@shujat132 i pasted php code what i have in this question. one more thing is it is working fine in localhost wamp server it is not working on live — asimdev, Sep 02 '20 at 10:45
