我試圖導入一個相當大的CSV文件到我的數據庫(本地) 該文件是230MB和它的約880萬行 我的問題是不打開CSV或不要知道如何導入它, 文件打開,導入大約500,000行,然後退出並且不會出現錯誤或超時或任何事情,我只能看到我的網頁。PHP導入CSV文件
這是代碼:
try {
$conn = new PDO("mysql:host=$servername;dbname=adresses_database", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully";
$row = 1;
if (($handle = fopen("bagadres.csv", "c+")) !== FALSE) {
while (($data = fgetcsv($handle, '', ";")) !== FALSE) {
if (!isset($write_position)) { // move the line to previous position, except the first line
$write_position = 0;
$num = count($data); // $num is 15
$row++; //i dont need this?
$stmt = $conn->prepare("INSERT INTO adresses (openbareruimte, huisnummer, huisletter, huisnummertoevoeging, postcode, woonplaats, gemeente, provincie, object_id, object_type, nevenadres, x, y, lon, lat) VALUES (:openbareruimte, :huisnummer, :huisletter, :huisnummertoevoeging, :postcode, :woonplaats, :gemeente, :provincie, :object_id, :object_type, :nevenadres, :x, :y, :lon, :lat)");
$stmt->bindParam(':openbareruimte', $data[0]);
$stmt->bindParam(':huisnummer', $data[1]);
$stmt->bindParam(':huisletter', $data[2]);
$stmt->bindParam(':huisnummertoevoeging', $data[3]);
$stmt->bindParam(':postcode', $data[4]);
$stmt->bindParam(':woonplaats', $data[5]);
$stmt->bindParam(':gemeente', $data[6]);
$stmt->bindParam(':provincie', $data[7]);
$stmt->bindParam(':object_id', $data[8]);
$stmt->bindParam(':object_type', $data[9]);
$stmt->bindParam(':nevenadres', $data[10]);
$stmt->bindParam(':x', $data[11]);
$stmt->bindParam(':y', $data[12]);
$stmt->bindParam(':lon', $data[13]);
$stmt->bindParam(':lat', $data[14]);
$stmt->execute();
} else {
$read_position = ftell($handle); // get actual line
fseek($handle, $write_position); // move to previous position
fputs($handle, $line); // put actual line in previous position
fseek($handle, $read_position); // return to actual position
$write_position += strlen($line); // set write position to the next loop
}
fflush($handle); // write any pending change to file
ftruncate($handle, $write_position); // drop the repeated last line
flock($handle, LOCK_UN);
}
fclose($handle);
}
}
catch(PDOException $e)
{
echo "Connection failed: " . $e->getMessage();
}
$conn = null;
我來到這麼遠尋找的計算器和PHP手冊的幫助,我也搜查,如果它是一個MySQL錯誤。 但我不明白這一點, (有關MySQL的設置有什麼建議即時通訊使用Linux Mint的18)
對不起,我沒有一個完整的答案給你。我以前住過這個,最後只是輸出到一個sql文件,將它放到服務器上並運行mysql來運行它。對不起,我沒有更多的建議:)我沒有時間找出爲什麼五十萬次迭代是一個上限...... –
