What are the best practices for handling CSV files in PHP, especially in terms of specifying the delimiter?

When working with CSV files in PHP, it is important to specify the delimiter correctly to ensure that the data is parsed correctly. The delimiter is the character used to separate the values in the CSV file. By default, PHP uses a comma (,) as the delimiter, but you can specify a different delimiter if needed, such as a tab (\t) or a pipe (|). To specify the delimiter when reading or writing CSV files in PHP, you can use the fgetcsv() and fputcsv() functions respectively, and pass the delimiter as the second parameter. 

// Specify the delimiter as a tab (\t) when reading a CSV file
$handle = fopen('data.csv', 'r');
while (($data = fgetcsv($handle, 0, "\t")) !== false) {
    // Process the data
}
fclose($handle);

// Specify the delimiter as a pipe (|) when writing to a CSV file
$data = array(
    array('John', 'Doe', 'john.doe@example.com'),
    array('Jane', 'Smith', 'jane.smith@example.com')
);
$handle = fopen('data.csv', 'w');
foreach ($data as $row) {
    fputcsv($handle, $row, '|');
}
fclose($handle);
