What are the potential performance issues of using massive file operations in PHP scripts?

Using massive file operations in PHP scripts can lead to performance issues due to the overhead of opening, reading, writing, and closing a large number of files. To improve performance, it's recommended to batch file operations together to reduce the number of file system calls. 

// Example of batching file operations to improve performance
$files = ['file1.txt', 'file2.txt', 'file3.txt'];

foreach ($files as $file) {
    // Perform file operations here
    // For example, reading or writing to the file
}
