PHP利用apc实现上传进度条方法
php本身是不具备可以带有实时上传进度条功能了,如果想有这种功能我们一般会使用ajax来实现,但是php提供了一个apc,他就可以与php配置实现上传进度条哦。
主要针对的是window上的应用。
1.服务器要支持apc扩展,没有此扩展的话,百度一下php_apc.dll ,下载一个扩展扩展要求php.5.2以上。
2.配置apc相关配置,重启apache
代码如下 | 复制代码 |
extension=php_apc.dll apc.rfc1867 = on apc.max_file_size = 1000M upload_max_filesize = 1000M post_max_size = 1000M |
说明一下:至于参数要配多大,得看项目需要apc.max_file_size, 设置apc所支持上传文件的大小,要求apc.max_file_size 3.在代码里面利用phpinfo();查看apc扩展安装了没有。
4.下面是实现代码:
getprogress.php
代码如下 | 复制代码 |
session_start(); PHP Code |
target.php
代码如下 | 复制代码 |
set_time_limit(600); if($_SERVER['REQUEST_METHOD']=='POST') { move_uploaded_file($_FILES["test_file"]["tmp_name"], dirname($_SERVER['SCRIPT_FILENAME'])."/UploadTemp/" . $_FILES["test_file"]["name"]);//UploadTemp文件夹位于此脚本相同目录下 echo " 上传成功 ";} ?> |
index.php
代码如下 | 复制代码 |
$id = md5(uniqid(rand(), true)); src="upload.php?id=" style="border: none; height: 100px; width: 400px;" > |

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
