Copy() function getting error in upload image with php code

Question

I'm having an unsolvable problem with uploading images to the server using php code. The code below is the file that uploads my images to the folder in the hosting, and saves the path to the database. I am using apache2 and php 7.4 with mysql. When I select the image to upload to the hosting directory, the

copy($_FILES['cons_image']['tmp_name'], $consname); 

do not copy the file to the directory on the hosting, and will lead to an error in this function.

if (!$copied) {
   echo '<h1>Copy unsuccessful!</h1>';
   $errors = 1;
  }

I tried everything to solve the problem, and people said that I installed the missing php_gd library, but when I checked the php.ini file I already installed GD, used the phpinfo.php file to check the library. GD, everything is on. But when I check the php.ini file in the paragraph

 [gd] 
; Tell the jpeg decode to ignore warnings and try to create 
; a gd image. The warning will then be displayed as notices ; disabled by
 default ; http://php.net/gd.jpeg-ignore-warning
 ;gd.jpeg_ignore_warning = 1

I don't see it having extension=gd line like in xampp on local machine. Can you help me check why the copy() function doesn't copy the images to the folder on my hosting. It still writes the path to the database but cannot copy the images to the hosting folder. I have included my code below hope anyone can help!

<?php
set_time_limit(0);

include './controllers/config.php';

//define a maxim size for the uploaded images
define("MAX_SIZE", "500");
// define the width and height for the thumbnail
// note that these dimensions are considered the maximum dimension and are not fixed, 
// because we have to keep the image ratio intact or it will be deformed
define("WIDTH", "187");  //set here the width you want your thumbnail to be
define("HEIGHT", "105");  //set here the height you want your thumbnail to be.

// this is the function that will create the thumbnail image from the uploaded image
// the resize will be done considering the width and height defined, but without deforming the image
function make_thumb($img_name, $filename, $new_w, $new_h) {
//get image extension.
    $ext = getExtension($img_name);
//creates the new image using the appropriate function from gd library
    if (!strcmp("jpg", $ext) || !strcmp("jpeg", $ext))

//gets the dimensions of the image
    $old_x = imageSX($src_img);
    $old_y = imageSY($src_img);

    // next we will calculate the new dimensions for the thumbnail image
// the next steps will be taken: 
//  1. calculate the ratio by dividing the old dimensions with the new ones
//  2. if the ratio for the width is higher, the width will remain the one define in WIDTH variable
//      and the height will be calculated so the image ratio will not change
//  3. otherwise we will use the height ratio for the image
// as a result, only one of the dimensions will be from the fixed ones
    $ratio1 = $old_x / $new_w;
    $ratio2 = $old_y / $new_h;
