Print/debug cause of upload error in PHP

I'm a PHP newbie and have written a script to process form uploads. It works for small files(less than 1Mb). However when I try to upload an ~4Mb pdf file it returns an error message. What am I doing wrong?

PS: I ran php_info, got the value of "upload_tmp_dir" and set it to a directory owned by the apache process(www-data)

My client-side code is

<form action="upper.php" method="post" enctype="multipart/form-data"> 
    <input type="file" name="myFile"><br>
    <input type="submit" value="Upload">
</form>

Upper.php contains

define("UPLOAD_DIR", "/var/www/html/upload/");

if (!empty($_FILES["myFile"])) {
    $myFile = $_FILES["myFile"];

    if ($myFile["error"] !== UPLOAD_ERR_OK) {
        echo "Error is " . $myFile["error"];
        //echo "<p>An error occurred.</p>";
        exit;
    }    

    $name = preg_replace("/[^A-Z0-9._-]/i", "_", $myFile["name"]);

    // don't overwrite an existing file
    $i = 0;
    $parts = pathinfo($name);
    while (file_exists(UPLOAD_DIR . $name)) {
        $i++;
        $name = $parts["filename"] . "-" . $i . "." . $parts["extension"];
    }

    // preserve file from temporary directory
    $success = move_uploaded_file($myFile["tmp_name"], UPLOAD_DIR . $name);
    if (!$success) {
        echo "<p>Unable to save file.</p>";
        exit;
    }

    // set proper permissions on the new file
    chmod(UPLOAD_DIR . $name, 0644);
}

You ned to set values in php.in file.
Open the file, Find upload_max_filesize and post_max_size lines.
Change this two value. (M= MB)

; Maximum allowed size for uploaded files.
upload_max_filesize = 20M
; Must be greater than or equal to upload_max_filesize
post_max_size = 20M

Restart the sever for effect.
Note:

  1. You can set any number. But not use any decimal value.
  2. Open the php.ini file in NOTEPAD. Don't user wordpad or any word processor.

Most probably you have wrong config in you php.ini file.

You need to set

; Maximum allowed size for uploaded files.
upload_max_filesize = 40M

; Must be greater than or equal to upload_max_filesize
post_max_size = 40M

its already described here: PHP change the maximum upload file size
