Solve the GD Chinese garbled problem_PHP tutorial

今天仔细研究了下GD的一些相关技术，顺手也研究下GD中文乱码的问题。

  使用GD库输出中文字符串，调用imagestring是没有用的。需要使用imagettftext()函数。imagettftext函数的具体使用就参考手册啦。

  下面给个使用实例：

   

<span style="COLOR: #000000"><br>$pic=imagecreate(250,30);  <br>$black=imagecolorallocate($pic,0,0,0);  <br>$white=imagecolorallocate($pic,255,255,255);  <br>$font="C://WINDOWS//Fonts//simhei.ttf";  //这里的路进需要注意下，必须是字符的路径 <br>$str ='php'.iconv('gb2312','utf-8','面对对象')." www.phpobject.net";  <br>imagettftext($pic,10,0,10,20,$white,$font,$str); <br>      </span>

    前面我给出一个简单的GD水印实例，只举例说明了使用图片如何水印的，这里给出一个文字水印的简单代码。
