What are the potential performance implications of using multiple includes in PHP?

Using multiple includes in PHP can lead to decreased performance due to the overhead of including and parsing multiple files. To improve performance, consider consolidating multiple includes into a single include statement or using autoloading to dynamically load classes only when they are needed.

// Consolidate multiple includes into a single include statement
include 'file1.php';
include 'file2.php';
include 'file3.php';

// Instead of the above, use a single include statement
include 'all_files.php';
