PHP实现视频文件上传完整实例,
PHP实现视频文件上传完整实例,
本文以一个完整实例的形式实现了视频文件上传的功能。虽然是比较基础的应用,仍有一定的参考价值。分享给大家供大家参考之用。具体方法如下:
首先,对PHP来说视频也属于文件,我们利用这个道理,可以通过与上传普通文件类似的方式实现上传PHP视频文件。不同的是视频文件一般较大,上传时间长,而php配置文件也对上传文件的大小有限制。
如果需要更好地用PHP实现文件上传,还是推荐使用FTP上传方式。
一、PHP处理代码如下:
<?php //设置最多允许10个文件同时上传 define('MUILTI_FILE_UPLOAD', '10'); //设置文件大小不超过5MB define('MAX_SIZE_FILE_UPLOAD', '500000' ); //设置上传文件的存储目录 define('FILE_UPLOAD_DIR', '/fileUploads'); //允许上传的文件扩展名 $array_extention_interdite = array( '.flv' , '.wmv' , '.rmvb' , '.php' , '.php3' , '.php4' , '.exe' , '.msi' , '.htaccess' , '.gz' ); //显示信息的公共函数 function func_message($message='', $ok=''){ echo '<table width="100%" cellspacing="0" cellpadding="0" border="0">'; if($ok == true) echo '<tr><td width="50%"> '.$message.'</td></tr>' ; else echo '<tr><td width="50%"> '.$message.'</td></tr>'; echo '</table>'; } //处理表单提交 $action = (isset($_POST['action'])) ? $_POST['action'] :'' ; $file = (isset($_POST['file'])) ? $_POST['file'] :'' ; if($file != '') $file = $file.'/'; $message_true = ''; $message_false = ''; switch($action){ case 'upload' : chmod(FILE_UPLOAD_DIR,0777); for($nb = 1 ; $nb <= MUILTI_FILE_UPLOAD ; $nb ++ ){ if( $_FILES['file_'.$nb]['size'] >= 10 ){ if ($_FILES['file_'.$nb]['size'] <= MAX_SIZE_FILE_UPLOAD ){ if (!in_array(ereg_replace('^[[:alnum:]]([-_.]?[[:alnum:]])*.' ,'.', $_FILES['file_'.$nb]['name'] ) , $array_extention_interdite) ){ if($_POST['file_name_'.$nb] !='') $file_name_final = $_POST['file_name_'.$nb].$extension ; else $file_name_final = $_FILES['file_'.$nb]['name'] ; //修改文件名 $file_name_final = strtr($file_name_final, 'aaaaaa', 'AAAAAACEEEEIIIIOOOOOUUUUYaaaaaaceeeeiiiioooooouuuuyy'); $file_name_final = preg_replace('/([^.a-z0-1]+)/i', '_', $file_name_final ); $_FILES['file_'.$nb]['name'] = $file_name_final; //开始上传 move_uploaded_file( $_FILES['file_'.$nb]['tmp_name'] , FILE_UPLOAD_DIR . $file . $file_name_final ); $message_true .= '文件上传成功 : '.$_FILES['file_'.$nb]['name'] .'<br>'; }else $message_false .= '文件上传失败 : '.$_FILES['file_'.$nb]['name'] .' <br>'; }else $message_false .= '文件最大尺寸不能超过'.MAX_SIZE_FILE_UPLOAD/1000 . 'KB : "'.$_FILES['file_'.$nb]['tmp_name'].'" <br>'; } }//end for break; } ?>
二、HTML代码如下:
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </head> <title>PHP文件上传</title> <style type="text/css" rel="stylesheet" /> .border{ background-color:#000000 } .box{ background-color:#f8f8f9; } .text{ color:#000000; font-family: "宋体"; font-size: 12px; font-weight:bold } input, select{ font-size: 12px; } body{ margin: 0; } </style> <body> <!-- 文件上传表单,enctype属性是必须的 --> <form name="form" enctype="multipart/form-data" method="post" action="<?php echo $_SERVER['PHP_SELF'] ; ?>"> <input type="hidden" name="action" value="upload"> <table border="0" cellspacing="1" cellpadding="0" align="center" class="border"> <tr> <td> <?php if($message_true != '') func_message($message_true, true); if($message_false != '') func_message($message_false, false); ?> <table width="100%" border="0" cellspacing="5" cellpadding="2" align="center" class="box"> <?php for($nb = 1 ; $nb <= MUILTI_FILE_UPLOAD ; $nb ++ ){ ?> <tr class="text"> <td>上传文件: <?php echo $nb; ?></td> <td><input type="file" name="file_<?php echo $nb; ?>"></td> <td>新文件名(包括扩展名):<?php echo $nb; ?> </td> <td><input type="text" name="file_name_<?php echo $nb; ?>"></td> </tr> <?php } ?> <tr> <td colspan="2" align="right" class="text"> 上传目的地址:<?php echo FILE_UPLOAD_DIR ;?> <select name="file"> <option value=""></option> <?php $repertoire = opendir(FILE_UPLOAD_DIR); while( $file = readdir($repertoire) ) { $file = str_replace('.','',$file); if( is_dir($file)) { ?> <option value="<?php echo $file; ?>"> <?php echo $file; ?>/</option> <?php } } closedir($repertoire); ?> </select> </td> <td colspan="2" align="right"><input type="submit" value="可同时上传<?php echo $nb-1; ?> 个文件 "></td> </tr> </table> </td> </tr> </table> </form> </body> </html>

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,

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.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.
