What are common issues with file uploads in PHP, especially when dealing with larger file sizes?

Common issues with file uploads in PHP, especially with larger file sizes, include exceeding the maximum file size allowed by PHP settings, running out of memory during the upload process, and encountering timeout issues due to long upload times. To solve these issues, you can adjust the PHP settings related to file uploads, increase the maximum file size limit, and optimize the upload process to handle larger files efficiently. 

// Increase the maximum file size limit in php.ini
// Adjust the following settings as needed
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '25M');
ini_set('memory_limit', '128M');

// Optimize the upload process to handle larger files efficiently
// This example shows how to handle file uploads using move_uploaded_file function
if ($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    $tmp_name = $_FILES['file']['tmp_name'];
    $upload_path = 'uploads/' . $_FILES['file']['name'];
    
    if (move_uploaded_file($tmp_name, $upload_path)) {
        echo 'File uploaded successfully!';
    } else {
        echo 'Failed to upload file.';
    }
} else {
    echo 'Error occurred during file upload.';
}
