CSV到数据库与php [英] CSV to database with php
问题描述
我有一个问题，将数据从.csv文件导入到ms access数据库。
I have a little issue with importing data from .csv file to "ms access" database.
<form action="index.php" method="post" enctype="multipart/form-data">
<input type="file" name="csv"/>
<input type="submit" name="submit"/>
</form>
<?php
if (isset($_POST['submit'])) {
$i=0;
require "connection.php";
if (is_uploaded_file($_FILES['csv']['tmp_name'])) {
echo "<h3>" . "File ". $_FILES['csv']['name'] ." uploaded successfully." . "</h3>";
}
//Import uploaded file to Database
$handle = fopen($_FILES['csv']['tmp_name'], "r");
$import=$db->prepare("INSERT INTO adherence(
dateandtime,
lastname,
paidtime,
approvedtime,
notadhering) VALUES(
?,?,?,?,?)");
while (($data = fgetcsv($handle, 1000, "\t", "'")) !== FALSE) {
if($i>0) {
$data = str_replace('"', '', $data);
$myDate = date("Y/m/d",strtotime(str_replace('/','-',$data[0])));
$import->bindParam(1, $myDate, PDO::PARAM_STR);
$import->bindParam(2, $data[1], PDO::PARAM_STR);
$import->bindParam(3, $data[2], PDO::PARAM_STR);
$import->bindParam(4, $data[3], PDO::PARAM_STR);
$import->bindParam(5, $data[4], PDO::PARAM_STR);
$import->execute();
}
$i++;
}
/*$removal=$db->prepare("delete FROM adherence WHERE approvedtime = '0' OR notadhering IS NULL");
$removal->execute();*/
fclose($handle);
echo 'IMPORTED' ;
}

导入结果：
我没有线索，为什么我的文件没有被导入，什么是这个随机日期。请协助！
I have no clue, why my file is not being imported, and what is this random date. Please assist!

连接正在工作，它是.MDB

推荐答案
您的根本问题是您不要指定逗号分隔符 fgetcsv（）函数。结果，所有的数据被推入一个列 date [0] / JET引擎无法转换为第一列的日期/时间，全部为零，这在
Your fundamental issue is you do not specify the comma delimiter in the fgetcsv() function. As a result, all the data pushed into one column, date[0] and the Access ACE/JET engine unable to convert to date/time of the first column rendered all to zero which in unix time begins at 1/1/1970.
另外，请考虑使用 try / catch 捕获PDO异常。
Also, consider using try/catch to catch PDO exceptions.
try {
$import= $dbh->prepare("INSERT INTO adherence(
dateandtime,
lastname,
paidtime,
approvedtime,
notadhering) VALUES(
?,?,?,?,?)");
$i = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
if($i > 0) {
$data = str_replace('"', '', $data);
$import->bindParam(1, $data[0], PDO::PARAM_STR);
$import->bindParam(2, $data[1], PDO::PARAM_STR);
$import->bindParam(3, $data[2], PDO::PARAM_STR);
$import->bindParam(4, $data[3], PDO::PARAM_STR);
$import->bindParam(5, $data[4], PDO::PARAM_STR);
$import->execute();
}
$i++;
}
}
catch(PDOException $e) {
echo $e->getMessage()."\n";
}
对于日期，MS Access日期/时间字段遵循当前CPU的语言时钟，例如 MM / DD / YYYY （US）或 DD / MM / YYYY （UK）等。它不遵循 YYYY-MM-DD 或其他RDMS的日期/时间格式。所以没有必要转换，因为你的csv已经对齐到Access'格式。正在说，您可能会收到警告：
As for dates, MS Access date/time field follows the current CPU's language clock such as MM/DD/YYYY (US) or DD/MM/YYYY (UK), etc. It does not follow the date/time format of other RDMS's of YYYY-MM-DD or such variants. So there is no need to convert since your csv aligned already to Access' format. With that being said, you may receive a warning:
SQLSTATE[22018]: Invalid character value for cast specification: -3030
但是，根据我的测试，数据库更新了所有行。通常，你会连接＃周围的日期字符串，我试图无法使用你的代码，但可能在你的绑定参数过程，字符串类型不理想地包装主题标签。
However, according to my tests, the database updated all rows correctly. Normally, you would concatenate the # around date strings which I tried to no avail with your code but possibly in your bind parameters process, string types do not wrap ideally with the hashtags.
