PHP implements an example of encapsulating a single file and uploading it to the database

This article mainly introduces the relevant information of PHP encapsulating a single file to be uploaded to the database (path). Friends in need can refer to it

1. First think about the question of uploading to the database whether it is an uploaded picture or a picture Address: What we upload here is the image address. Because the image or audio is too large to be stored in the database, the database will collapse.

The following is the method for uploading encapsulated files:

$maxSize){ return [0,'传的文件超过最大限制']; } //判断文件的mime类型 if(!in_array($_FILES[$key]['type'],$allowMime)){ return [0,'不符合的mime类型']; } //判断文件的后缀 $info = pathinfo($_FILES[$key]['name']); $sub = $info['extension']; if(!in_array($sub,$allowType)){ return [0,'不符合的文件后缀']; } //判断是否是随机文件 if($ifFileName){ $name = uniqid().'.'.$sub; }else{ $name = $info; } //拼接路径 $path = rtrim($path,'/').'/'.date('Y/m/d').'/'; //判断文件是否存在,不存在则创建 if(!file_exists($path)){ mkdir($path,0777,true); } //判断是否是上传文件 if(is_uploaded_file($_FILES[$key]['tmp_name'])){ if(move_uploaded_file($_FILES[$key]['tmp_name'],$path.$name)){ echo '文件上传成功'; return [1,$path.$name]; }else{ return[0,'上传文件失败']; } }else{ return [0,'文件不存在']; } }
