本文實例講述了PHP簡單生成縮略圖相冊的方法。分享給大家供大家參考。具體如下：

<?php

/*

* written by mot

* 根目錄下自己新建image thumb目錄

* */

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();

}

希望本文所述對大家的php程序設計有所幫助。
