限制图像上传文件大小

Question

目前我的php验证如下

if ($_FILES["file"]["size"] > 5120) 
{
$_SESSION['error'] = 'Upload FAILED, file is too large !';
header("Location: upload.php");
exit;
}

但这似乎并没有阻止任何大型文件上传！任何帮助非常感谢!!

Answer 1

使用此选项限制上传文件大小：

$max_size = /* whatever */; //File Size in Bytes

if(filesize($_FILES['userfile']['tmp_name']) > $max_size) {
      die('The file you uploaded is too large.');
    }

Answer 2

使用upload_max_filesize

可以在php.ini，.htaccess，httpd.conf或.user.ini中设置条目
