Base64 image string into image file using PHP - php

Question

I need code to convert a base64 image string into an image file and write into local directory using PHP. I tried:
function user_profile_photo(){
$input = urldecode(file_get_contents('php://input'));
$received = json_decode($input, true);
$user_id = $received['user_id'];
$img = $received['imagecode'];
$imagedata = base64_decode($img);
$image_path='uploads/images/'.$user_id;
$path = '/var/www/html/empengapp/uploads/images/'.$user_id;
if (!file_exists($path)) {
mkdir($path, 0755, true);
}
$new_name = date('ymd').time().'.jpg';
$pathwithfile = '/var/www/html/empengapp/uploads/images/'.$user_id.'/'.$new_name;
$success = file_put_contents($pathwithfile, $imagedata);
var_dump($imagedata);exit;
$this->output
->set_status_header(200)
->set_content_type('application/json', 'utf-8')
->set_output(json_encode($resp, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES))
->_display();
exit;
}//end of function user_profile_photo
It is writing a file with given extension, but when you try to open file it shows an invalid file error.

I figure it out the solution.
$pathwithfile = 'your file path with image name';//e.g '/uploads/test.jpg'
$ifp = fopen( $pathwithfile, 'wb' );
// split the string on commas
// $data[ 0 ] == "data:image/png;base64"
// $data[ 1 ] == <actual base64 string>
$data = explode( ',', $imagedata );
$success = fwrite( $ifp, base64_decode( $data[ 1 ] ) ); // clean up the file resource
fclose( $ifp );
I was sending over the API to PHP server. You need to encode your image base64 string and your image base64 string must include "data:image/jpeg;base64". We are splitting it on PHP server But don't think to send image base54 without "data:image/jpeg;base64".
But remember one thing you have to use image base64 including
