Are there any best practices for efficiently using count() and glob() in PHP?

When using count() and glob() in PHP, it's important to use them efficiently to avoid unnecessary processing and improve performance. One best practice is to avoid calling count() multiple times on the same array or result set, as it can be computationally expensive. Instead, store the count value in a variable if it will be used multiple times. Additionally, when using glob() to retrieve files, consider using the GLOB_NOSORT flag if you don't need the results to be sorted, as it can improve performance. 

// Example of efficiently using count() and glob()

// Store the count value in a variable if it will be used multiple times
$files = glob('path/to/files/*.txt');
$numFiles = count($files);

// Use the $numFiles variable instead of calling count() multiple times
echo "Number of files: " . $numFiles;

// Use the GLOB_NOSORT flag if sorting is not necessary
$filesNoSort = glob('path/to/files/*.txt', GLOB_NOSORT);
