What is the significance of using enctype="multipart/form-data" in a PHP form for file uploads?
When uploading files through a form in PHP, it is important to use the enctype="multipart/form-data" attribute in the <form> tag. This attribute specifies how the form data should be encoded when submitting it to the server, allowing files to be included in the request. Without this attribute, the file data will not be properly transmitted to the server for processing.
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit" value="Upload">
</form>
