php单个文件上传类codeguy/upload使用

阅读更多

注意：此扩展依赖于php的fileinfo扩展
mamp套件中已包含，只需在php.ini中添加一句
extension=php_fileinfo.dll，即可。
linux系统则：
yum install php-fileinfo
=================================
注意，上传相关配置
nginx
增加如下两行到nginx.conf的http{}段， 增大nginx上传文件大小限制
#设置允许发布内容为8M
client_max_body_size 8M;(说明，此参数可以放http段，也可以放server段，后者优先级高)

send_timeout    60;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;

====================================
php.ini
post_max_size = 8M
upload_max_filesize = 8M

另外，看情况设置
max_execution_time = 600 ;每个PHP页面运行的最大时间值(秒)，默认30秒
max_input_time = 600 ;每个PHP页面接收数据所需的最大时间，默认60秒
memory_limit = 8m ;每个PHP页面所吃掉的最大内存，默认8M

==============================
php-fpm注意参数
request_terminate_timeout
request_slowlog_timeout
这两个参数如果设置过小的话会导致文件传输了一部分后连接关闭。

=============================
composer配置

示例代码

上传demo";
if ($_SERVER['REQUEST_METHOD']=='GET') {
	echo <<
	    
			



	    
    
html;
	exit;
} 

$storage = new \Upload\Storage\FileSystem(__DIR__."/upload");
if (count($_FILES)>0) {
	$keys = array_keys($_FILES);
	$form_file_name = $keys[0];
	$file = new \Upload\File($form_file_name, $storage);
}else {
	exit;
}


// Optionally you can rename the file on upload
$new_name=uniqid();
$file->setName($new_name);

// Validate file upload
// MimeType List => http://www.iana.org/assignments/media-types/media-types.xhtml
$file->addValidations(array(
		//You can also add multi mimetype validation
		new \Upload\Validation\Mimetype(array('image/png', 'image/gif', 'image/jpeg')),
		// Ensure file is no larger than 5M (use "B", "K", M", or "G")
		new \Upload\Validation\Size('5M'),
));

// Try to upload file
try {
	// Success!
	$file->upload();
	echo "upload success,新文件名：".$file->getNameWithExtension();
} catch (\Exception $e) {
	// Fail!
	$errors = $file->getErrors();
	echo $errors[0];
}
