PHP简单生成缩略图相册的方法

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();
    }
