一款简单PHP图片上传类带图片显示代码
这是一款简单PHP图片上传类带图片显示代码,应该可以说是上传文件最简单的上传类了,可以设置要显示图片高度与宽度,文件大小等.
uploadimg.class.php文件,代码如下:
class upload { var $upload_name ; var $upload_tmp_address ; var $upload_server_name ; var $upload_filetype ; var $file_type ; var $file_server_address ; var $image_w =900; //要显示图片的宽 var $image_h =350; //要显示图片的高 var $upload_file_size ; var $upload_must_size = 50000; //允许上传文件的大小，自己设置 function upload_file() { $this ->upload_name = $_files [ "file" ][ "name" ]; //取得上传文件名 $this ->upload_filetype = $_files [ "file" ][ "type" ]; $this ->upload_server_name = date ( "y_m_dh_i_s" ). $this ->upload_name; $this ->upload_tmp_address = $_files [ "file" ][ "tmp_name" ]; //取得临时地址 $this ->file_type = array ( "image/gif" , "image/pjpeg" ); //允许上传文件的类型 $this ->upload_file_size = $_files [ "file" ][ "size" ]; //上传文件的大小 if (in_array( $this ->upload_filetype, $this ->file_type)) { if ( $this ->upload_file_size < $this ->upload_must_size) { echo ( "上传成功，谢谢支持" ); $this ->file_server_address = "d:www.111cn.netupload/" . $this ->upload_server_name; move_uploaded_file( $this ->upload_tmp_address, $this ->file_server_address); //从temp目录移出 echo ( "<img src=$this->file_server_address width=$this->image_w height=$this->image_h/>" ); //显示图片 } else { echo ( "文件容量太大" ); } } else { echo ( "不支持此文件类型，请重新选择" ); //开源代码phpfensi.com } } }html上传代码,代码如下:
< form id = "form1" name = "upload" enctype = "multipart/form-data" method = "post" action = "upload.php" > < input type = "hidden" name = "max_file_size " /> < input type = "file" name = "file" /> < input type = "submit" name = "submit" value = "提交" /> </ form >调用方法,upload.php,代码如下:
