PHP 一次只能看到 20 个上传文件
当我尝试一次上传超过 20 个文件时，Web 服务器只会看到前 20 个文件.任何其他文件都将被忽略.有什么问题?
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?
简单代码尝试:
<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
我刚刚在本地服务器上的 php.ini 中添加了一行:
I just added line to php.ini on my local server :
max_file_uploads = 100
这很有帮助.但我不认为宿主在客户端的网络服务器上改变它.不编辑 php.ini.
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max-file-uploads 设置更高(是的，这是一个新"设置).
Set the max-file-uploads setting higher (yes, it's a 'newish' setting).
它是 PHP_INI_SYSTEM，所以它可以设置在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.
