嘗試從CSV導(dǎo)入數(shù)據(jù)時(shí)遇到了一些問題，但還有一些問題，我還沒有解決。首先，這是我的代碼，可以幫助您更好地了解事物（將其整理一些，刪除CSS和DB連接）：<body><div id="container"><div id="form"><?php$deleterecords = "TRUNCATE TABLE tablename"; //empty the table of its current recordsmysql_query($deleterecords);//Upload Fileif (isset($_POST['submit'])) { if (is_uploaded_file($_FILES['filename']['tmp_name'])) { echo "<h1>" . "File ". $_FILES['filename']['name'] ." uploaded successfully." . "</h1>"; echo "<h2>Displaying contents:</h2>"; readfile($_FILES['filename']['tmp_name']); } //Import uploaded file to Database $handle = fopen($_FILES['filename']['tmp_name'], "r"); while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $import="INSERT into importing(text,number)values('$data[0]','$data[1]')"; mysql_query($import) or die(mysql_error()); } fclose($handle); print "Import done";//view upload form} else { print "Upload new csv by browsing to file and clicking on Upload<br />\n"; print "<form enctype='multipart/form-data' action='upload.php' method='post'>"; print "File name to import:<br />\n"; print "<input size='50' type='file' name='filename'><br />\n"; print "<input type='submit' name='submit' value='Upload'></form>";}?></div></div></body>從本質(zhì)上講，這是我對(duì)各種方法進(jìn)行多次嘗試后發(fā)現(xiàn)的示例的改編。我的CSV有兩列數(shù)據(jù)，第一列是文本，第二列是整數(shù)數(shù)據(jù)庫中的表也有兩列，第一列稱為“文本”，第二列為“數(shù)字”所以我的問題是：正在上傳的文本只是在每個(gè)字段中顯示為0，我不確定為什么我一直在閱讀有關(guān)以“”括起來的數(shù)據(jù)的信息，如果發(fā)生這種情況，我將如何對(duì)其進(jìn)行排序？如何忽略標(biāo)題等的CSV的前X行？在整個(gè)過程中數(shù)據(jù)格式是否已更改，或者是否可以在圖形中使用？例如，一旦放入數(shù)據(jù)庫，小數(shù)點(diǎn)會(huì)保留小數(shù)點(diǎn)嗎？我想涵蓋了所有內(nèi)容，在此先感謝您的幫助！編輯：剛剛對(duì)10,000條記錄上傳進(jìn)行了測(cè)試，但出現(xiàn)錯(cuò)誤：“致命錯(cuò)誤：超過30秒的最大執(zhí)行時(shí)間”有什么想法嗎？

$i=0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
if($i>0){
$import="INSERT into importing(text,number)values('".$data[0]."','".$data[1]."')";
mysql_query($import) or die(mysql_error());
}
$i=1;
}

letsay $ infile = a.csv //需要導(dǎo)入文件。
class blah
{
static public function readJobsFromFile($file)
{
if (($handle = fopen($file, "r")) === FALSE)
{
echo "readJobsFromFile: Failed to open file [$file]\n";
die;
}
$header=true;
$index=0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE)
{
// ignore header
if ($header == true)
{
$header = false;
continue;
}
if ($data[0] == '' && $data[1] == '' ) //u have oly 2 fields
{
echo "readJobsFromFile: No more input entries\n";
break;
}
$a = trim($data[0]);
$b = trim($data[1]);
if (check_if_exists("SELECT count(*) FROM Db_table WHERE a='$a' AND b='$b'") === true)
{
$index++;
continue;
}
$sql = "INSERT INTO DB_table SET a='$a' , b='$b' ";
@mysql_query($sql) or die("readJobsFromFile: " . mysql_error());
$index++;
}
fclose($handle);
return $index; //no. of fields in database.
}
function
check_if_exists($sql)
{
$result = mysql_query($sql) or die("$sql --" . mysql_error());
if (!$result) {
$message = 'check_if_exists::Invalid query: ' . mysql_error() . "\n";
$message .= 'Query: ' . $sql;
die($message);
}
$row = mysql_fetch_assoc ($result);
$count = $row['count(*)'];
if ($count > 0)
return true;
return false;
}
$infile=a.csv;
blah::readJobsFromFile($infile);
}
希望這可以幫助。
