在 PHP 中将 CSV 文件导入 Mysql 数据库答案

【问题标题】：Import CSV file to Mysql Database in PHP在 PHP 中将 CSV 文件导入 Mysql 数据库

【问题描述】：

我尝试使用 LOAD DATA LOCAL INFILE 从另一台服务器导入 csv 文件，但它给了我一个错误 The user update failed: Can't find file，即使该文件存在于给定的路径中。我也试过LOAD DATA INFILE 但User access denied

有没有其他方法可以将csv文件直接导入mysql数据库中的文件路径（不使用任何提交按钮），如果有新的csv文件上传，则删除dbase表中的当前数据？

编辑：我也尝试了这个 PHP 脚本，在没有任何按钮的情况下导入 csv 文件，但是 csv 文件数据没有导入

PHP（第二个代码）：

$mysqli = new mysqli("localhost", "user", "password", "dbasename");
$file = "/var/www/html/files/filename.csv";
$handle = fopen($file,'r');
while (($data = fgetcsv($handle, 10000, ",")) !== FALSE){
     $num = count($data);
     for ($c=0; $c < $num; $c++){
         $col[$c] = $data[$c];
     }

     $col1 = $data[0];
     $col2 = $data[1];
     $col3 = $data[2];
     $col4 = $data[3];
     $col5 = $data[4];

     // SQL Query to insert data into DataBase
     $query = "INSERT INTO dbname.tablename(col1,col2,col3,col4,col5) VALUES('".$col1."','".$col2."','".$col3."','".$col4."','".$col5."')";
     $mysqli->query($query);
}
fclose($handle);

这是 PHP：

$sql = "LOAD DATA LOCAL INFILE 'filename.csv'
       INTO TABLE dbname.tablename
       FIELDS TERMINATED BY ','
       OPTIONALLY ENCLOSED BY '\"' 
       LINES TERMINATED BY '\n' 
       IGNORE 1 LINES;";

$con=mysqli_connect("localhost","user","password","db");
// Check connection
if (mysqli_connect_errno()){
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
};

$result = mysqli_query($con, $sql);

if (mysqli_affected_rows($con) == 1){
  $message = "The data was successfully added!";
} else {
  $message = "The user update failed: ";
  $message .= mysqli_error($con); 
};

echo $message;

@e4c5，我不是要导出数据，而是要将其导入 mysql 数据库。我不这是重复的

【解决方案1】：

你也可以试试

$con=mysqli_connect("localhost","user","password","db");
$file = fopen("filename.csv","r");
while ($data = fgetcsv ($file)){
     print_r($data);
     $sql = 'insert into ...'
     $result = mysqli_query($con, $sql);
}

导入 csv 文件

【解决方案2】：

<?php 
	$connect = mysqli_connect("localhost", "root", "", "testing");
	if(isset($_POST["submit"]))
{
	if($_FILES['file']['name'])
	{
		$filename = explode(".", $_FILES['file']['name']);
		if($filename[1] == 'csv')
		{
			$handle = fopen($_FILES['file']['tmp_name'], "r");
			while($data = fgetcsv($handle))
			{
				$item1 = mysqli_real_escape_string($connect, $data[0]);  
				$item2 = mysqli_real_escape_string($connect, $data[1]);
				$query = "INSERT into excel(excel_name, excel_phone) values('$item1','$item2')";
				mysqli_query($connect, $query);
			}
			fclose($handle);
			echo "<script>alert('Import done');</script>";
		}
	}
}
