Why can’t I upload more than 2mb with this script?

Question

<form action="" method="post" enctype="multipart/form-data">
  <input type="file" name="fileUpload"/><br/>
  <button type="submit">Enviar</button>
</form>

<?php
if ($_SERVER["REQUEST_METHOD"]==="POST"){
    $file = isset($_FILES["fileUpload"])?$_FILES["fileUpload"]:"";
    if($file["error"]){

    }

    $dirUploads = "uploads";
    if(!is_dir($dirUploads)){
        mkdir($dirUploads);
    }
   if (move_uploaded_file($file["tmp_name"],$dirUploads.DIRECTORY_SEPARATOR.$file["name"])){
       echo "upload realizado com sucesso"."<br>";

   }else{
       throw new Exception("Não foi possivel fazer o upload");
  }
}
?>

Make a phpinfo.php file using the code below:

<?php phpinfo(); ?>

And open it in the browser. In the "Loaded Configuration File" part, the path to the configuration file used will appear, usually php.ini. Of course, if it’s not shared hosting and you have access to change it.

You can also create a php.ini file at the root of your project.

In php.ini, change the part:

upload_max_filesize: (maximum upload size)

post_max_size:(maximum size of the posted data but also affects file uploading)

memory_limit:(maximum amount of byte memory the script can allocate. This must be greater than "post_max_size")

max_execution_time:(Maximum running time)

While uploading large files, it is important not to leave a very short time, as errors may occur if you do not have time to upload the entire file.

Also note if the user has access to record in the directory where the uploaded file will be saved.
