PHP implements upload file class-PHP Tutorial-php.cn

The following editor will bring you an example of implementing common file upload classes in PHP. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

The code is as follows:

_path = $path; $this->_allowType = array( // images 'bmp' => 'image/x-ms-bmp', 'jpg' => 'image/jpeg', 'jpeg' => 'image/jpeg', 'gif' => 'image/gif', 'png' => 'image/png', 'tif' => 'image/tiff', 'tiff' => 'image/tiff', 'tga' => 'image/x-targa', 'psd' => 'image/vnd.adobe.photoshop', //文本 'txt' => 'text/plain', 'php' => 'text/x-php', 'html' => 'text/html', 'htm' => 'text/html', 'js' => 'text/javascript', 'css' => 'text/css', 'rtf' => 'text/rtf', 'rtfd' => 'text/rtfd', 'py' => 'text/x-python', 'java' => 'text/x-java-source', 'rb' => 'text/x-ruby', 'sh' => 'text/x-shellscript', 'pl' => 'text/x-perl', 'sql' => 'text/x-sql', //应用 'exe' => 'application/octet-stream', 'doc' => 'application/vnd.ms-word', 'docx' => 'application/vnd.ms-word', 'xls' => 'application/vnd.ms-excel', 'ppt' => 'application/vnd.ms-powerpoint', 'pps' => 'application/vnd.ms-powerpoint', 'pdf' => 'application/pdf', 'xml' => 'application/xml', //音频 'mp3' => 'audio/mpeg', 'mid' => 'audio/midi', 'ogg' => 'audio/ogg', 'mp4a' => 'audio/mp4', 'wav' => 'audio/wav', 'wma' => 'audio/x-ms-wma', //视频 'avi' => 'video/x-msvideo', 'dv' => 'video/x-dv', 'mp4' => 'video/mp4', 'mpeg' => 'video/mpeg', 'mpg' => 'video/mpeg', 'mov' => 'video/quicktime', 'wm' => 'video/x-ms-wmv', 'flv' => 'video/x-flv', 'mkv' => 'video/x-matroska' ); } /** * 上传函数 * @param string : 表单元素的name 值 * @return [type] */ public function upload( $txtName = '' ) { $this->_file = $_FILES[$txtName]; if( $this->_file['error'] == 0){ $fileType = end( explode('.', $this->_file['name'] )); $allowType = array(); foreach( $this->_allowType as $item=>$value ){ $allowType[] = $item; } if( !in_array($fileType, $allowType)){ die('上传的文件格式不正确！'); }else{ if(move_uploaded_file($this->file['tmp_name'], ($this->path).$this->file['name'])) { echo ""; } else { echo ""; } } }else{ //没有正确上传 switch ($this->file['error']){ case 1: die('文件大小超过系统限制。'); break; case 2: die('文件大小超过预定义限制。'); break; case 3: die('文件为完全上传。'); break; case 4: die('未上传任何文件。'); break; default: die('上传出错'); break; } } } //end upload }
