I have to upload excel file's data to MySQL database using php. I have found the code for that but I am unable to upload large files.

Can anyone please tell me that how can I increase the max file size limit for the code mentioned in below link:

http://www.9code.in/how-to-import-excel-file-to-mysql-database-using-php/

<!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");
}

You can use LOAD DATA command in MySQL : Read More

you have to used load data in mysql statement. This can load your large file in database.

mysqli_query($dblink, '
    LOAD DATA LOCAL INFILE "'.$file.'"
        INTO TABLE transactions
        FIELDS TERMINATED by ","
        OPTIONALLY ENCLOSED BY "\'"
        LINES TERMINATED BY "\n"
');

  • I cant use coz that much access is not given to normal user...I need to create an interface from where they can upload data from excel – Darshan May 26 '14 at 12:24
  • by default upload / import size in phpmyadmin is 2MB. you can increase your upload_max_filesize = 20M , post_max_size = 20M in your apache php.ini.try it – truesource May 26 '14 at 12:52
  • I Tried but the problem remains the same – Darshan May 27 '14 at 05:07
  • It says: The file you attempted to upload is too large... The filename excel_file/1401167648140116764829 is not readable – Darshan May 27 '14 at 05:15
  • Can you check the code here : https://drive.google.com/file/d/0Bz6rEtX6kxclMFRBa1U1ZkpTWlE/edit?usp=sharing – Darshan May 27 '14 at 05:16
  • I think load data is the solution for uploading large file. so you can try above query to upload your file in your database. – truesource May 27 '14 at 05:28

Look at these values in your php.ini

upload_max_filesize = 10M post_max_size = 10M

You need to set the value of upload_max_filesize and post_max_size in your php.ini :

; Maximum allowed size for uploaded files.
upload_max_filesize = 40M

; Must be greater than or equal to upload_max_filesize
post_max_size = 40M

I have to add that you have to restart the server

  • I did as you said but the problem remains the same.... I think the source code needs to be edited.. You can check the source file in the below link.. https://drive.google.com/file/d/0Bz6rEtX6kxclMFRBa1U1ZkpTWlE/edit?usp=sharing – Darshan May 27 '14 at 04:53

According to ASNAOUI Ayoub I made the following changes:

; Maximum allowed size for uploaded files.
upload_max_filesize = 40M

; Must be greater than or equal to upload_max_filesize
post_max_size = 40M

But Stil the Problem was same then I tried to change the 

$max_filesize = 41943040

Now It perfectly works.....

Thanks Everyone for the help
