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:
<?php 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"); } } } ?>
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:
inlcude('uploadimg.class.php'); $dd = new upload; $dd->upload_file();
