我在Excel（.xlsx）中有大约60000行的大量数据，我正在使用 Spout 库在MySQL中插入所有数据以读取Excel数据，并且从excel文件中读取数据后还有一些详细信息不是Unicode格式，也不是英语（当前数据使用印地语），因此我首先使用 Python 脚本将此非标准文本转换为Unicode，然后将Unicode数据印地语转换为使用 Google Translate API 使用英语。.一切正常，但是要花很多时间。在所有这些步骤之后，在我当前的脚本中将200行插入MySQL，这大约需要20分钟。.我的问题是如何改善当前脚本以提高性能 这是我当前的脚本：
// Convert local hindi font to unicode
function KridevToUnicode($k) {
$myfile = fopen("input.txt", "w");
fwrite($myfile, $k);
fclose($myfile);
shell_exec('krutidev2unicode.py -i input.txt -o output.txt');
$file = fopen("output.txt","r");
return hindiToEnglish(fgets($file));
fclose($file);
}
// Convert hindi to english
function hindiToEnglish($text) {
$apiKey2 = 'XXXXXXXXXXXXXXXXXXXXX';
$url = 'https://www.googleapis.com/language/translate/v2?key=' . $apiKey2 . '&q=' . rawurlencode($text) . '&source=hi&target=en';
$handle = curl_init($url);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($handle);
$responseDecoded = json_decode($response, true);
curl_close($handle);
return $responseDecoded['data']['translations'][0]['translatedText'];
}
