复制代码 代码如下:
codes = implode('',array_slice($codearray,0,4));
}
public function createimg()
{
$_session['check_pic'] = $this->codes;
$img = imagecreate(70,25);
imagecolorallocate($img,222,222,222);
$testcolor1 = imagecolorallocate($img,255,0,0);
$testcolor2 = imagecolorallocate($img,51,51,51);
$testcolor3 = imagecolorallocate($img,0,0,255);
$testcolor4 = imagecolorallocate($img,255,0,255);
for ($i = 0; $i {
imagestring($img,rand(5,6),8 + $i * 15,rand(2,8),$this->codes[$i],rand(1,4));
}
imagegif($img);
}
}
$code = new securitycode();
$code->createimg();
$code = null;
?>
封装成类之后，加入了构造函数，使用起来也方便些。你也可以继续完善下这个验证码类，比如加入析构函数，如何更节省内存等等。
