How can beginners in PHP improve their skills in handling file uploads and avoid common errors like selecting the wrong file?

Beginners in PHP can improve their skills in handling file uploads by implementing proper validation techniques to ensure that the correct file type and size are being uploaded. One common error is selecting the wrong file unintentionally, which can be avoided by providing clear instructions and using file input fields with the "accept" attribute set to the desired file type. 

// Example code snippet to restrict file uploads to only accept image files
<form action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="image" accept="image/*">
    <input type="submit" value="Upload Image">
</form>
