Php上传文件方法

前台页面:
<form action="../control/filecontrol.php" method="post" enctype="multipart/form-data">
<table border="1" width="100%">
	<tr>
		<td>选择图片</td>
		<td><input type="file" name="file_file"/></td>
	</tr>
	<tr>
		<td>图片名称</td>
		<td><input type="text" name="down_name"/></td>
	</tr>
	<tr>
		<td colspan="2"><input type="submit" value="保存文件" /></td>
	</tr>
</table>
</form>

上传操作页面:
if(isset ( $_FILES ["file_file"] )){
		$file = @$_FILES['file_file'];
		
		//上传验证
		if ($file["error"] > 0) {
			echo "上传错误!";
			exit;
		} 
		
		//对文件大小对比1000KB以下的图片可以上传
		$fileSize = sprintf("%.2f",($file["size"] / 1024 / 1024)); //M
		if($fileSize > 100){
			echo "文件太大超过100M不能上传!";
			exit;
		}
		
		//文件名称
		$down_name = $file['name'];
		$down_urlname = StackConst::get_date_str().substr($down_name,strrpos($down_name,"."),strlen($down_name));
		
		//从缓存区移动文件
		if(move_uploaded_file($file["tmp_name"],StackConst::res_file_url().$down_urlname)){
			
			
			//装填信息
			$arrFileInfo = array(
								"down_name"=>@$_POST['down_name'],
								"down_urlname"=>$down_urlname,
								"down_savedate"=>StackConst::get_date()
			);
			
			//引入FileDao
			require_once '../dao/FileDao.php';
			//实例化FileDao
			$fileDao = new FileDao();
			
			if($fileDao->addFileSource($arrFileInfo)){
				echo "文件上传成功!";
				StackConst::jump_page("../view/filelist.php");
			}else{
				echo "文件上传失败!";
			}
		}else{
			echo "文件上传失败!";
		}
		
	}

其中这里包括了把上传文件的信息写入数据库

FileDao.php
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<?php 
header ( 'Content-type: text/html; charset=utf-8' );
ini_set("error_reporting","E_ALL & ~E_NOTICE");

		//链接数据库
		$conn = ConnMysqlClass::getConnMysql();

		$str_sql = "select down_id,down_name,down_urlname,down_savedate,down_statue from rea1_resource_down order by down_id desc";

}

还有个是:【获取各种类型的时间串,上传里面用到了】
<?php
//关闭异常报错
ini_set("error_reporting","E_ALL & ~E_NOTICE");
//设置时间格式
date_default_timezone_set('Asia/Shanghai');

class StackConst {
	
	/**

	 */
	static public function get_date_min(){

		$dateTime = date('Ymd');
		//返回系统时间
		return $dateTime;
	}
	
	/**
	 * @return Y-m-d
	 */
	static public function get_date_sort(){
		//获取时间
		$dateTime = date('Y-m-d');
		//返回系统时间
		return $dateTime;
	}
	/**
	 * @return Y-m-dH:i:s
	 */
	static public function get_date(){
		//获取时间
		$dateTime = date('Y-m-d H:i:s');
		//返回系统时间
		return $dateTime;
	}
	
	/**
	 * @return 获取时间戳
	 */
	static public function get_date_str(){
		
		//获取时间
		$dateTime = date('Y-m-d H:i:s');
		
		//获得时间串
		$year=((int)substr($dateTime,0,4));//取得年份
		$month=((int)substr($dateTime,5,2));//取得月份
		$day=((int)substr($dateTime,8,2));//取得几号
		$second = ((int)substr($dateTime,11,2));//取得几号
