Are there any specific considerations or adjustments that need to be made when coding PHP scripts for handling file uploads to ensure cross-browser compatibility?

When handling file uploads in PHP, it's important to consider cross-browser compatibility. One common issue is that different browsers may send file upload data in different formats. To ensure compatibility, you can use PHP's built-in functions like `$_FILES` to handle file uploads consistently across browsers. 

<?php
// Check if the file was uploaded without errors
if(isset($_FILES['file']) && $_FILES['file']['error'] == UPLOAD_ERR_OK) {
    $uploadDir = 'uploads/';
    $uploadFile = $uploadDir . basename($_FILES['file']['name']);

    // Move the uploaded file to the desired directory
    if(move_uploaded_file($_FILES['file']['tmp_name'], $uploadFile)) {
        echo 'File uploaded successfully!';
    } else {
        echo 'File upload failed.';
    }
} else {
    echo 'Error uploading file.';
}
?>
