本篇文章主要介绍php生成缩略图的方法，感兴趣的朋友参考下，希望对大家有所帮助。

PHP上传图片、生成缩略图是比较常用到的功能，一般我们会把这些功能写一个类，方便我们调用。今天发现了一个比较简单些的PHP生成缩略图函数的代码，不敢独享，特此与大家分享。自己使用时候认真看一下，代码中都有注释的。

本文实例讲述了PHP简单生成缩略图相册的方法。具体如下：

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 "src>"; } } $hl = opendir(".\\image\\"); while(false != $file = readdir($hl)){ if($file == '.' || $file == '..') continue; $path = '.\\image\\'.$file; $tmp = new thumb($path,0.3); $tmp->make(); }
