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
/*
*writtenbymot
*根目录下自己新建imagethumb目录
**/
classthumb{
private$src;
private$source;
private$s_width;
private$s_height;
private$dest;
private$d_height;
private$d_width;
private$name;
publicfunctionthumb($image_path,$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];
}
publicfunctionmake(){
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"<ahref=$this->src><imgsrc=$img></a>";
}
}
$hl=opendir(".\\image\\");
while(false!=$file=readdir($hl)){
if($file=='.'||$file=='..')continue;
$path='.\\image\\'.$file;
$tmp=newthumb($path,0.3);
$tmp->make();
}
希望本文所述对大家的php程序设计有所帮助。
