使用mysqli

Question

我有一个数据库，正在将一个较大的csv文件加载到其中。直到最近，下面的脚本都可以正常工作，并且我还没有对脚本本身进行任何更改，但是它突然停止了工作...

CSV文件的示例是

"Offer.ID","Offer.PhoneCost","Offer.TotalCost","Offer.MonthlyCost","Offer.FreeGift","Offer.FreeGiftImage","Offer.FreeGiftCategory","Offer.FullFreeGift","Offer.OfferCashback","Offer.AutoCashback","Offer.Clearance","Offer.OfferMins","Offer.OfferTxts","Offer.OfferRental","Offer.OfferLength","Offer.OfferText","Offer.Link"
"8676820","0.00","165.00","13.75","","","","15.00 Guaranteed Cashback","15.00","1","0","0","0","15.00","0","£15.00 Automatic Cashback","http://www.urmob.co.uk/t/a/psav89/URMOB-xmakex-xmodelx-xtariffx/track.php%253fid=8676820"

我正在使用的PHP脚本是...

<?php

require_once 'dbconnect.php';

$dbh = db_connect();
$log = fopen("database-log.txt", "w");

$time = date("Y-m-d H:i:s"); 


//start the log
$logstart = "------------------------------------------------\n" . $time . " log start\n------------------------------------------------\n\n";
fwrite($log, $logstart);


//clean the temp table
$query = "TRUNCATE TEMPDATA";
$trunc = mysqli_query($dbh, $query);

if($trunc){
    fwrite($log, "TEMPDATA cleared\n");
} else {
    fwrite($log, "TEMPDATA failed\n");
}

//load affiliate window csv
$query = "load data local infile '/home/data.csv' into table rim6jtvnox6vmwxk.TEMPDATA FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n' IGNORE 1 ROWS";
$update = mysqli_query($dbh, $query);

fwrite($log, $update);

if($update){
    fwrite($log, "TEMPDATA Table updated with CSV\n");
} else {
    fwrite($log, "Failed CSV update - " . mysqli_error($dbh) . "\n");
}

mysqli_close($dbh);

$endtime = date("Y-m-d H:i:s"); 
$logend = "\n\n------------------------------------------------\n" . $endtime . " log end\n------------------------------------------------\n";
//end the log
fwrite($log, $logend);
fclose($log);

?>

我知道与数据库的连接正在正常工作，并且可以看到数据库已清除。但是加载脚本似乎没有执行，也没有从mysqli_error发出任何错误。

任何不起作用的想法将不胜感激。
