Question

我想将csv加载到mysql中并管理单个字段。原始代码使用自动VALUES（''，'$ linemysql'）上传内容;我怎么能把田地分开？我会查询：

$sql = "INSERT IGNORE INTO `database`.`table` (`field1`,field2`, `field3`, `field4`, `field5`) VALUES(`csvfield1`,csvfield2`, `csvfield3`, `csvfield4`, `csvfield5`);";

这是因为我可以管理哪一行将被包括在内非常感谢

$lines = 0;
$queries = "";
$linearray = array();

$allLines = split($lineseparator,$csvcontent);
array_shift($allLines); // removes the 1st element

foreach($allLines as $line) {

$lines++;

$line = trim($line," \t");

$line = str_replace("\r","",$line);

/************************************
This line escapes the special character. remove it if entries are already escaped in the csv file
************************************/
$line = str_replace("'","\'",$line);
/*************************************/

$linearray = explode($fieldseparator,$line);

$linemysql = implode("','",$linearray);

if($addauto)

/* Change This query VALUES('','$linemysql'); */

    $query = "INSERT IGNORE INTO `database`.`table` (`field1`,field2`, `field3`, `field4`, `field5`) VALUES('','$linemysql');";

else
    $query = "insert into $databasetable values('$linemysql');";

$queries .= $query . "\n";

Answer 1

使用PHP的内置CSV功能，包括fgetcsv()。来自文档：

<?php
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($c=0; $c < $num; $c++) {
            echo $data[$c] . "<br />\n";
        }
    }
    fclose($handle);
}
?>

Answer 2

您可以像这样修改您的查询

$query = "INSERT IGNORE INTO `database`.`table` (`field1`,field2`, `field3`, `field4`, `field5`) VALUES("'.$linemysql[0].'","'.$linemysql[1].'","'.$linemysql[2].'","'.$linemysql[3].'","'.$linemysql[4].'");";

由于

在查询中单独的Csv导入字段
