Php 上载大于2 mb的文件时出错,php,Php,我有2个php文件：第一名称form_upload.php <html> <head><title>File Upload</title></head> <body> <ol> <li>Enter the file name of the product picture you want to upload or the the browse button

我有2个php文件：第一名称form_upload.php

 <html>
    <head><title>File Upload</title></head>
    <body>
    <ol>
        <li>Enter the file name of the product picture you want to upload or the the browse button to navigate to the picture file</li>
        <li>when the path to the picture file shows in the text field, click the upload picture</li>
    </ol>

    <form enctype="multipart/form-data" action="uploadFile.php" method="POST">
    <input type="hidden" name="MAX_FILE_SIZE" value="500000"/>
    <input type="file" name="pix" size="60"/>
    <p><input type='submit' name="Upload" value="Upload picture"/></p>
    </form>
    </body>
    </html>


文件上传
输入要上载的产品图片的文件名，或使用“浏览”按钮导航到图片文件
当文本字段中显示图片文件的路径时，单击上载图片

第二：uploadFile.php

<?php

if(!isset($_POST['Upload']))
{
    include("form_upload.php");
}
else
{
    if($_FILES['pix']['tmp_name']=="none")
    {
        echo "file did not successfully upload. Check the file size. File must be less than 500K";
        include("form_upload.php");
        exit();
    }
    if(!preg_match("/image\/jpeg/",$_FILES['pix']['type']))
    {
        echo "only jpg files are allowed. Please try another file";
        include("form_upload.php");
        exit();
    }
    else
    {
        $destination='C:\xampp\htdocs\test\hinh\ '.$_FILES['pix']['name'];
        $temp_file=$_FILES['pix']['tmp_name'];
            move_uploaded_file($temp_file,$destination);
        echo "<p>the file has successfully uploaded :{$_FILES['pix']['name']} {$_FILES['pix']['type']} ({$_FILES['pix']['size']}) </p>";


    }
}

添加
在htaccess中
或更改此值
upload_max_filesize = 10M
post_max_size = 10M

在php.ini中
然后重新启动web服务器
10M代表10兆字节，如果（$\u FILES['pix']['tmp\u name']==“none”），您可以插入另一个值
，
--这与文件大小有什么关系？很可能是主机设置。。。。默认限制通常为2兆请注意，MAX\u FILE\u SIZE
设置为。。。对于应用程序客户端的用户来说，这只是一个方便的特性<代码>最大大小的PHP设置（在服务器端）不能被愚弄。

当然假设主机允许访问PHP.ini或允许htaccess覆盖

upload_max_filesize = 10M
post_max_size = 10M
