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();
