使用PHP将Windows-1252 csv转换为UTF-8

$file = fopen('file.csv', 'r');
$data = array();
while (!feof($file)) {
    $data[] = fgets($file);
}
fclose($file);

$utf8_data = array();
foreach ($data as $row) {
    $utf8_row = iconv('Windows-1252', 'UTF-8', $row);
    $utf8_data[] = $utf8_row;
}

$new_file = fopen('new_file.csv', 'w');
foreach ($utf8_data as $row) {
    fputs($new_file, $row);
}
fclose($new_file);

$file = fopen('file.csv', 'r');
$data = array();
while (!feof($file)) {
    $data[] = fgets($file);
}
fclose($file);

$utf8_data = array();
foreach ($data as $row) {
    $utf8_row = iconv('Windows-1252', 'UTF-8', $row);
    $utf8_data[] = $utf8_row;
}

$new_file = fopen('new_file.csv', 'w');
foreach ($utf8_data as $row) {
    fputs($new_file, $row);
}
fclose($new_file);
