我不得不使用PHP excel文件的数据上传到MySQL数据库。 我已经找到了该代码，但我无法上传大文件。
谁能告诉我，我怎么能增加最大文件大小限制为下面的链接中提到的代码：

<!DOCTYPE html>
<?php
include 'db.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
$MaxID = $MaxID . $ext;
}
}
return $MaxID;
}
if(isset($_POST['submit']))

{

//print_r($data);
$query="INSERT INTO StudentData(FirstName,LastName,MobileNo,City)VALUES('".$data[0]."','".$data[1]."','".$data[2]."','".$data[3]."')";
mysql_query($query);

}
