PHP一次只能看到20个上传文件 [英] PHP see only 20 uploading files at a time

问题描述

当我尝试一次上传20个以上的文件时，Web服务器只会看到前20个文件.其他任何文件都将被忽略.有什么问题吗?

When I try to upload more than 20 files at a time, then the web server see only first 20. Any other files are just ignored. What is the problem?

尝试的简单代码:

<form action="index.php" method="post" enctype="multipart/form-data">
<?php
if($_FILES){
    print_r($_FILES);
}
else{
    for($i = 0; $i < 30; $i++)
    {
        echo '<input type="file" name="file'.$i.'"><br/>';
    }
}
?>
<input type="submit" value="go">
</form>

print_r()输出:

.htaccess: php_value max_file_uploads 100-没有帮助

.htaccess: php_value max_file_uploads 100 - doesn't help

ini_set('max_file_uploads', 100) - doesn't help

我刚刚将行添加到本地服务器上的php.ini中:

I just added line to php.ini on my local server :

max_file_uploads = 100

这很有帮助.但是我不认为托管者会在客户端的Web服务器上对其进行更改.如果不编辑php.ini，对这个值将是非常酷的效果.

And it's helped. But I don't think that the hoster change it on client's web server. It would be very cool effect on this value without editing php.ini.

推荐答案

设置最大文件上传设置(是的，这是新的"设置).

Set the max-file-uploads setting higher (yes, it's a 'newish' setting).

它是 PHP_INI_SYSTEM ，因此可以在以下位置进行设置php.ini或webserver/apache配置.恐怕没有.htaccess或脚本内"访问权限.

It's PHP_INI_SYSTEM, so it can either be set in php.ini or webserver/apache configuration. No .htaccess or 'in-script' access I'm afraid.
