What are some potential pitfalls when working with CSV files in PHP and storing the data in arrays?

One potential pitfall when working with CSV files in PHP and storing the data in arrays is memory consumption, especially when dealing with large CSV files. To mitigate this issue, it's recommended to process the CSV file line by line instead of loading the entire file into memory at once. 

// Open the CSV file for reading
$csvFile = fopen('data.csv', 'r');

// Initialize an empty array to store the data
$data = [];

// Read the CSV file line by line and store each row in the array
while (($row = fgetcsv($csvFile)) !== false) {
    $data[] = $row;
}

// Close the CSV file
fclose($csvFile);

// Now $data contains the CSV data stored in an array
