In the context of PHP, what are the best practices for handling file creation and checking for file existence in a loop?

When creating or checking for file existence in a loop in PHP, it is important to ensure that the file operations are handled efficiently and without errors. To achieve this, you can use functions like `fopen()` to create files and `file_exists()` to check for file existence. It is also recommended to use proper error handling techniques, such as checking for errors returned by these functions and handling them accordingly. 

// Example of creating files and checking for existence in a loop

$files_to_create = ['file1.txt', 'file2.txt', 'file3.txt'];

foreach ($files_to_create as $file) {
    $file_handle = fopen($file, 'w');
    
    if ($file_handle === false) {
        echo "Error creating file: $file\n";
    } else {
        fclose($file_handle);
        echo "File created: $file\n";
    }
    
    if (file_exists($file)) {
        echo "File exists: $file\n";
    } else {
        echo "File does not exist: $file\n";
    }
}
