Php 查询中单独的CSV导入字段

我希望将csv加载到MySQL并管理单个字段。原始代码使用自动

值（'''$linemysql'）上传内容。我怎样才能把这些字段分开？我想提出以下问题：

$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要包括的行

$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";

使用PHP内置的CSV功能，包括。从文档中：

<?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);
}
?>

您可以这样修改查询

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

谢谢
使用。我认为是正确的，但报告此错误：解析错误：语法错误，意外的T_常量\u封装的\u字符串
