Change Image File Size (Height And Width) While Uploading

Thanks for the support really appreciated.

I am newbie in PHP, and i heard that i can find my solution from those PHP expert who are here in CODEMILES.

I have bought this script a while ago and now the producer stopped offering support.

My Question

The script have ability to upload profile for every user but it doesn't resize the image.
If a user upload a 2 mb image so the script use 2 mb image in all over the website which makes my website to run slower.

I want that the script should resize the image to

([width=100px and height=auto] and

[width=19px and height=auto])

so i use a lighter image in size (like ~150 kb and ~55kb) and let my site run faster.

This is the avatar.php file that process the uploading

Code:

<?php
    // declare variables
    $msg = '';
    $f_avatar_image = '';
    // ------------------------------------------------------------
    // UPLOAD AVATAR
    // ------------------------------------------------------------
    if(isset($_POST['btnUploadAvatar']) && !empty($_FILES['fileUpload']['name']))
    {
       // create variables
       $avatar_directory = AVATAR_FILE_DIRECTORY;
       $file_name = $_FILES['fileUpload']['name'];
       $file_type = $_FILES['fileUpload']['type'];
       $file_size = $_FILES['fileUpload']['size'];
       $file_size_limit = AVATAR_FILE_SIZE;
       $calc_kilobites = 1024;
       $file_size_kb = round($file_size / $calc_kilobites, 2);
       $temp_file_name = $_FILES['fileUpload']['tmp_name'];
       $upload_error = $_FILES['fileUpload']['error'];
       
       
       // create unique file name
       $unique_file_name = $user_name.'-'.$file_name;
       $avatar_img_url = AVATAR_IMAGE_URL.$user_name.'-'.$file_name;
   
       // if upload error display error message
       if($upload_error > 0)
       {
          echo 'ERROR:' . $upload_error;
       }
   
       // if no upload error - check for file types
       if($upload_error == 0 &&
       $file_type == 'image/gif' ||
       $file_type == 'image/jpeg' ||
       $file_type == 'image/png' )
       {
          // if file size is within limits
          if($file_size <= $file_size_limit)
          {
             // move uploaded file to assigned directory
             if(move_uploaded_file($temp_file_name, $avatar_directory . $unique_file_name))

    if($user_name)

       else
       {
          $f_avatar_image = AVATAR_IMAGE_URL.DEFAULT_AVATAR_IMAGE;
       }
    }
    ?>

This is the avatar.html.php file form

Code:

<?php require_once(ROOT_PATH.'user/modules/accordion/avatar.php'); ?>
    <div class="profileWrap">
      <form name="frmAvatar" method="post" action="" enctype="multipart/form-data" class="htmlForm">
        <div class="infoBanner2">
          <p>REQUIREMENTS:  File Size: <?php echo AVATAR_FILE_SIZE / 1024 ?> kb max. File Type: gif, jpg, png</p>
        </div>
        <!-- error msgs -->
        <ul>
        <?php echo $msg; ?>
        </ul>
        <p><input name="selectFile" type="image" src="<?php echo $f_avatar_image; ?>" class="img"></p>
        <p><label for="fileUpload">Avatar Image:</label><input name="fileUpload" type="file" id="fileUpload" maxlength="255" ></p>
        <input name="btnUploadAvatar" type="submit" value="Upload" class="gvbtn btn" onclick="return confirm('Are You READY to UPLOAD?');"/>
      </form>
    </div>

The avatar.php file is linked to a configuration file (web.config.php) file

Code:

// ------------------------------------------------------------
    // 16. AVATAR IMAGE FILE
    // ------------------------------------------------------------
    define('AVATAR_FILE_SIZE', 2097152); // 50 Kb max. -> 1 kilobyte = 1024 bytes
    define('AVATAR_FILE_DIRECTORY', ROOT_PATH.'user/upload/avatars/'); // upload directory
    define('AVATAR_IMAGE_URL', SITE_URL.'user/upload/avatars/'); // default avatar url
    define('DEFAULT_AVATAR_IMAGE', 'default-avatar.png'); // default avatar image
