What are the best practices for optimizing the loading process of large arrays in PHP for setup data?

When loading large arrays of setup data in PHP, it's important to optimize the loading process to avoid memory issues and improve performance. One way to do this is by using the `fopen()` function to read the data from a file line by line, rather than loading the entire array into memory at once. This allows you to process the data in smaller chunks, reducing memory usage and improving efficiency. 

$filename = 'setup_data.txt';
$handle = fopen($filename, 'r');

if ($handle) {
    $setupData = [];
    
    while (($line = fgets($handle)) !== false) {
        $setupData[] = $line;
    }
    
    fclose($handle);
    
    // Process the setup data as needed
} else {
    echo "Error opening file.";
}
