How to solve the Chinese garbled problem of php gd?

Today I carefully studied some related technologies of GD, and also studied the problem of Chinese garbled characters in GD.

Using the GD library to output Chinese strings, calling imagestring is useless. You need to use the imagettftext() function. Please refer to the manual for the specific use of the imagettftext function.

Here is a usage example:

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