Question

我正在处理通过网络接收的此脚本，以将文件上传到服务器文件夹。该脚本工作正常，但它只允许重量小于2 MB的jpeg图像。我通过添加其他格式来加载代码来修改代码，它很有用，不幸的是不再考虑重量限制（2 mb）。我哪里错了？谢谢（我附上原始和编辑的脚本）

原创剧本

<?php
require('connect.php');
$name = $_FILES['file']['name'];
$size = $_FILES['file']['size'];
$type = $_FILES['file']['type'];

$tmp_name = $_FILES['file']['tmp_name'];

$extension = substr($name, strpos($name, '.') + 1);

$max_size = 2000000;
if(isset($name) && !empty($name)){
	if(($extension == "jpg" || $extension == "jpeg") && $type == "image/jpeg" && $extension == $size<=$max_size){
		$location = "uploads/";
        
       if(move_uploaded_file($tmp_name, $location.$name)){

        		$result = mysqli_query($connection, $query);

Codice modificato

＆＃13;

if(isset($name) && !empty($name)){
	if(($extension == "jpg" || $extension == "jpeg") && $type == "image/jpeg" || $type == "image/png " || $type == "image/gif" && $extension == $size<=$max_size){
		$location = "uploads/";

＆＃13;

我想我会错过语法，有人可以帮助我吗？

<?php
require('connect.php');
$name = $_FILES['file']['name'];
$size = $_FILES['file']['size'];
$type = $_FILES['file']['type'];

$tmp_name = $_FILES['file']['tmp_name'];

$extension = substr($name, strpos($name, '.') + 1);

$max_size = 2000000;
if(isset($name) && !empty($name)){
	if(($type == "image/jpeg" || $type == "image/png" || $type == "image/gif" || $type == "application/x-zip-compressed") && ($size<=$max_size)){

这是最终的解决方案。感谢@ADyson的宝贵帮助。如果有进一步的步骤来改进脚本，那么它们很受欢迎

默认情况下，pхp.ini中的Giorgio设置为2 MB： upload_max_filesize = 2M 可能按顺序 - 824。您需要使用所需的值更改它。
