PHP简单生成缩略图相册的方法
这篇文章主要介绍了PHP简单生成缩略图相册的方法,实例分析了php生成缩略图的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下，本文实例讲述了PHP简单生成缩略图相册的方法，分享给大家供大家参考，具体如下：
- <?php
- /*
- * written by mot
- * 根目录下自己新建image thumb目录
- * */
- class thumb{
- private $src;
- private $source;
- private $s_width;
- private $s_height;
- private $dest;
- private $d_height;
- private $d_width;
- private $name;
- public function thumb($image_path,$rate = 0.5){
- $this->src = $image_path;
- $this->source = imagecreatefromjpeg($image_path);
- $s_size = getimagesize($image_path);
- $this->s_height = $s_size[1];
- $this->s_width = $s_size[0];
- $this->d_height = 100;
- $this->d_width = 100;
- $this->dest = imagecreate($this->d_width, $this->d_height);
- $this->name = explode('.jpg', $image_path);
- $this->name = $this->name[0];
- }
- public function make(){
- imagecopyresized($this->dest, $this->source, 0, 0, 0, 0, $this->d_width, $this->d_height,
- $this->s_width, $this->s_height);
- $thumb = str_replace('image', 'thumb', $this->name.'-thumb.jpg');
- imagejpeg($this->dest,$thumb,100);
- $img = $thumb;
- echo "<a href=$this->src><img src=$img></a>";
- }
- }
- $hl = opendir(".\\image\\");
- while(false != $file = readdir($hl)){
- if($file == '.' || $file == '..') continue;
- $path = '.\\image\\'.$file;
- $tmp = new thumb($path,0.3);
- $tmp->make();
- }
