Are there best practices for handling file access and array management in PHP to prevent memory leaks or other issues?

To prevent memory leaks and other issues when handling file access and array management in PHP, it is important to close file handles after use and unset arrays when they are no longer needed. This helps free up memory and prevents resource leaks.

// Open a file for reading
$file = fopen("example.txt", "r");

// Read file content
$content = fread($file, filesize("example.txt"));

// Close the file handle
fclose($file);

// Unset the array
unset($content);
