PHP接收上传文件
前言
这星期一直再搞php，涉及到文件上传的部分有些遗忘，这里记录一下HTML的form表单
用html的表单模拟一个文件上传的post请求，代码如下：<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>File Upload</title> </head> <body> </body> </html>
注意：
要确保文件上传表单的属性是 enctype="multipart/form-data",否则文件上传不了
PHP
首先，需要解释一下PHP的全局变量$_FILES，此数组包含了所有上传的文件信息$_FILE['userfile']['name'] : 客户端机器文件的原名称
$_FILE['userfile']['type'] : 文件的MIME类型
$_FILE['userfile']['size'] : 已上传的文件大小
$_FILE['userfile']['tmpname'] : 文件被上传后在服务器存储的临时文件名
$_FILE['userfile']['error'] : 和该文件上传的错误代码
思路
1、生成40位的随机字符串作为文件名 2、根据文件是图片还是语音转存到不同的文件位置 3、暂时不做文件大小和文件类型的校验function processFile($files, $type) {
$uploadName = null;
foreach ($files as $name => $value) {
$originalName = $value['name'];
$arr = explode(".", $originalName);
$postfix = $arr[count($arr) - 1];
$tmpPath = $value['tmp_name'];
$tmpType = $value['type'];
$tmpSize = $value['size'];
}
$newname = EhlStaticFunction::generateRandomStr(40).".".$postfix;
switch ($type) {
case 1 :
// 处理声音文件
$destination = VIDEOUPLOADDIR.$newname;
break;
case 2 :
// 处理图像文件
$destination = IMAGEUPLOADDIR.$newname;
break;
}
move_uploaded_file($tmpPath, $destination);
}

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
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,
