代码演示：

<?php  
 	header("content-type: image/png");//如果要看报什么错，可以先注释调这个header
	$nickname = "昵称";//微信昵称
	$erweimaurl = "image/erweima.png";//二维码
	$logourl = "image/0.png";//微信头像	
	$beijing = "image/1.png";//海报最底层得背景
	$beijing = imagecreatefrompng($beijing);
	$logourl = imagecreatefrompng($logourl);
	$erweimaurl = imagecreatefrompng($erweimaurl);
	$image_3 = imageCreatetruecolor(imagesx($beijing),imagesy($beijing));
	$color = imagecolorallocate($image_3, 255, 255, 255);
	imagefill($image_3, 0, 0, $color);
	imageColorTransparent($image_3, $color);
	imagecopyresampled($image_3,$beijing,0,0,0,0,imagesx($beijing),imagesy($beijing),imagesx($beijing),imagesy($beijing));   
    //字体颜色
    $white = imagecolorallocate($image_3, 111, 255, 255);
    $rqys = imagecolorallocate($image_3, 255, 255, 255);
    $black = imagecolorallocate($image_3,120,84,26);
    $font = "simhei.ttf";  //写的文字用到的字体。字体最好用系统有得，否则会包charmap的错，这是黑体	
    //imagettftext设置生成图片的文本    
	imagettftext($image_3,32,0,240,55,$rqys,$font,$nickname);
	imagecopymerge($image_3,$logourl, 0,0,0,0,160,160,100);//左，上，右，下，宽度，高度，透明度
	//imagecopymerge($image_3,$erweimaurl, 120,100,0,0,imagesx($erweimaurl),imagesy($erweimaurl), 100);
    imagecopymerge($image_3,$erweimaurl, 120,100,0,0,imagesx($erweimaurl),imagesy($erweimaurl), 100);
    //生成图片
    imagepng($image_3);//在浏览器上显示
	//imagepng($image_3,"d:a.png");保存到本地
    imagedestroy($im);
