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();}

希望本文所述对大家的php程序设计有所帮助。
