PHP 大文件上传进度条实现_PHP
目前我知道的方法有两种,一种是使用PHP的创始人 Rasmus Lerdorf 写的APC扩展模块来实现(http://pecl.php.net/package/apc),另外一种方法是使用PECL扩展模块uploadprogress实现(http://pecl.php.net/package/uploadprogress) 我这里举两个分别实现的例子供参考,更灵活的应用根据自己需要来修改。
APC实现方法:
安装APC,参照官方文档安装,可以使用PECL模块安装方法快速简捷,这里不说明
配置php.ini,设置参数 apc.rfc1867=1 ,使APC支持上传进度条功能,在APC源码说明文档里面有说明
代码范例:
if ($_SERVER['REQUEST_METHOD'] == ‘POST‘) { //上传请求 $status = apc_fetch(‘upload_‘ . $_POST['APC_UPLOAD_PROGRESS']); $status['done'] = 1; echo json_encode($status); //输出给用户端页面里的ajax调用,相关文档请自己寻找 exit; } elseif (isset($_GET['progress_key'])) { //读取上传进度 $status = apc_fetch(‘upload_‘.$_GET['progress_key']); echo json_encode($status); exit; } else { //其他代码,比如上传表单等 } |
uploadprogress 模块实现方法:
使用PECL模块安装方法安装该模块
php.ini里面设置 uploadprogress.file.filename_template = “/tmp/upd_%s.txt”
代码范例:
if($_SERVER['REQUEST_METHOD']==‘POST‘) { if (is_uploaded_file($_FILES['upfile']['tmp_name'])) { $upload_dir = ‘your_path/‘; $ext = strrchr($_FILES['video']['name'], ‘.‘); $sessid = $_POST['UPLOAD_IDENTIFIER'] ; $tmpfile = $upload_dir . $sessid; $sessfile = $upload_dir . $sessid .$ext; if (move_uploaded_file($_FILES['upfile']['tmp_name'],$tmpfile)) { //上传成功 } else { //上传失败 } else { //上传错误 } elseif (!empty($_GET['sessid'])) { header(“Expires: Mon, 26 Jul 1997 05:00:00 GMT“); header(“Last-Modified: “ . gmdate(“D, d M Y H:i:s“) . “ GMT“); header(“Cache-Control: no-store, no-cache, must-revalidate“); header(“Cache-Control: post-check=0, pre-check=0“, false); header(“Pragma: no-cache“); header(“Content-Type:text/html;charset=UTF-8“); $unique_id = $_GET['sessid']; $uploadvalues = uploadprogress_get_info($unique_id); if (is_array($uploadvalues)) { echo json_encode($uploadvalues); } else { //读取进度失败,另外处理逻辑 } } else { //显示上传表单 } |

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo
