如何使用PHP将大型Excel文件导入MySql数据库
我必须使用PHP将excel文件的数据上传到MySQL数据库。 我已经find了代码，但我无法上传大文件。
任何人都可以告诉我，如何增加下面链接中提到的代码的最大文件大小限制：

<!DOCTYPE html> <?php include 'db.php'; include 'Excel/reader.php'; function uploadFile($fieldName, $fileType, $folderName, $name = "") { $flg = 0; $MaxID = ""; $ext = ""; $uploadfile = ""; if (isset($fieldName) AND $fieldName['name'] != '') { $flg = 1; $allowed_filetypes = $fileType; // I Need to increase this..... I tried changing values but nothing happened $max_filesize = 1048576; $filename = $fieldName['name']; if ($name == "") $MaxID = time() . time() . rand(1, 100); else $MaxID = $name; $ext = substr($filename, strpos($filename, '.'), strlen($filename) - 1); if($ext==".xlsx") $ext=".xls"; if (!in_array($ext, $allowed_filetypes)) echo "<h1>The file you attempted to upload is not allowed...</h1>"; else if (filesize($fieldName['tmp_name']) > $max_filesize) echo "<h1>The file you attempted to upload is too large...</h1>"; else { $uploadfile = $folderName . "/" . $MaxID . $ext; if (move_uploaded_file($fieldName['tmp_name'], $uploadfile) == FALSE) { echo "<h1>Error in Uploading File...</h1>"; $MaxID = ""; } else $MaxID = $MaxID . $ext; } } return $MaxID; } if(isset($_POST['submit'])) { if($_FILES['csvFile']['name']!="") { $fileName=uploadFile($_FILES['excelFile'],array(".csv"),"excel_file"); $row=0; if(($handle = fopen("excel/".$fileName , "r")) !== FALSE) { while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $num = count($data); //print_r($data); $query="INSERT INTO StudentData(FirstName,LastName,MobileNo,City)VALUES('".$data[0]."','".$data[1]."','".$data[2]."','".$data[3]."')"; mysql_query($query); } fclose($handle); } } else if($_FILES['excelFile']['name']!="") { $fileName=uploadFile($_FILES['excelFile'],array(".xls",".xlsx"),"excel_file"); $data = new Spreadsheet_Excel_Reader(); $data->read('excel_file/'.$fileName); for($i=1;$i<=$data->sheets[0]['numRows'];$i++) { $firstname=$data->sheets[0]['cells'][$i][1]; $lastname=$data->sheets[0]['cells'][$i][2]; $mobile=$data->sheets[0]['cells'][$i][3]; $city=$data->sheets[0]['cells'][$i][4]; $query="INSERT INTO StudentData(FirstName,LastName,MobileNo,City)VALUES('".$firstname."','".$lastname."','".$mobile."','".$city."')"; mysql_query($query); } } } if(isset($_POST['delete'])) { mysql_query("DELETE FROM StudentData"); } ?> 您可以在MySQL中使用LOAD DATA命令： 阅读更多
你必须在mysql语句中使用加载数据。 这可以加载您的大型文件在数据库中。
mysqli_query($dblink, ' LOAD DATA LOCAL INFILE "'.$file.'" INTO TABLE transactions FIELDS TERMINATED by "," OPTIONALLY ENCLOSED BY "\'" LINES TERMINATED BY "\n" ');
看看你的php.ini中的这些值
upload_max_filesize = 10M post_max_size = 10M
您需要在php.ini中设置upload_max_filesize和post_max_size的值：
; Maximum allowed size for uploaded files. upload_max_filesize = 40M ; Must be greater than or equal to upload_max_filesize post_max_size = 40M
我必须补充说，你必须重新启动服务器
根据ASNAOUI Ayoub，我作了如下修改：
; Maximum allowed size for uploaded files. upload_max_filesize = 40M ; Must be greater than or equal to upload_max_filesize post_max_size = 40M
但是，Stil的问题是一样的，我试图改变
$max_filesize = 41943040
现在它完美的作品…..
谢谢大家的帮助
