php csv文件如何读写

读取CSV文件:

$file = fopen('data.csv', 'r');while (($data = fgetcsv($file)) !== false) {    print_r($data);}fclose($file);

写入CSV文件:

$data = [    ['John', 'Doe', 'john.doe@example.com'],    ['Jane', 'Smith', 'jane.smith@example.com'],];$file = fopen('data.csv', 'w');foreach ($data as $row) {    fputcsv($file, $row);}fclose($file);
