What are some potential pitfalls of using txt files instead of SQL for storing data in PHP applications?

One potential pitfall of using txt files instead of SQL for storing data in PHP applications is the lack of structured querying capabilities. This can make it difficult to efficiently retrieve and manipulate data. To solve this issue, you can use a PHP library like SplFileObject to read and write data to txt files in a more organized manner.

$file = new SplFileObject('data.txt', 'r');
$file->setFlags(SplFileObject::READ_CSV);

foreach ($file as $row) {
    // Process each row of data
}

$file = new SplFileObject('data.txt', 'w');
$file->fputcsv($data);
