使用php将文件上传到表单需要什么？

Question

I'm creating a job application form in which a user adds his resume and it's attached to an email, everything worked fine for file less than 1 MB size, if it's more when I click submit the server takes so much time then gives me a server timeout error.

This is the html:

      <div class="form-group">
        <label for="personalCV">CV</label>
        <input
         name="personalCV"
         type="file"
         class="form-control"
         id="personalCV"
         placeholder="Attach CV"
         style="height: auto;"

         value="<?php if (isset($personalCV)){echo $personalCV;} ?>"
         required>
         <span>File Shouldn't exceed 2MB, and must be of formats .doc, .docx, .pdf</span>

      </div>

This is the php:

  if ($_SERVER['REQUEST_METHOD'] == 'POST') {

    //assign variables//
    $firstName = filter_var($_POST['firstName'] , FILTER_SANITIZE_STRING);
    $lastName = filter_var($_POST['lastName'] , FILTER_SANITIZE_STRING);
    $email = filter_var($_POST['userEmail'] , FILTER_SANITIZE_EMAIL);
    $phoneNum = filter_var($_POST['phoneNum'] , FILTER_SANITIZE_NUMBER_INT);
    $position = $jobTitle;
    $message = filter_var($_POST['message'] , FILTER_SANITIZE_STRING);
    $path = 'upload/' . $_FILES["personalCV"]["name"];
    move_uploaded_file($_FILES["personalCV"]["tmp_name"], $path);

I guess the problem is that when i click on the form submit button the file starts to upload which takes some time more than the server timeout, is there a way where the user waits for the file to upload first (maybe use a progress bar), then after it uploads user clicks submit form and it's sent to email, or will the problem still persist.

PHP has several configuration options to limit resources consumed by scripts. By default, PHP is set to allow uploads of files with a size of 2MB or less.

Try increasing the following values in php.ini, for example:

memory_limit = 32M
upload_max_filesize = 24M
post_max_size = 32M
