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。
