首先，确定服务器中已经安装并开启GD2图形库

然后，代码如下：

ob_clean();         

 

$realname = "姓名";

$schoolname = "学校";  

$idcard = "身份证号"; 

 

$image = imagecreatefrompng('certification.png');           // 证书模版图片文件的路径 

$red = imagecolorallocate($image,00,00,00);                 // 字体颜色

 

// imageTTFText("Image", "Font Size", "Rotate Text", "Left Position","Top Position", "Font Color", "Font Name", "Text To Print");

imageTTFText($image, 50, 0, 1110, 1025, $red, '字体路径',$realname);

imageTTFText($image, 50, 0, 1000, 1023, $red, '字体路径', $schoolname);

imageTTFText($image, 55, 0, 900, 810, $red, '字体路径（/usr/share/fonts/truetype/ttf-dejavu/simhei.ttf）', $idcard);

 

 /* If you want to display the file in browser */

header('Content-type: image/png;');

ImagePng($image);

imagedestroy($image);

 

 

/* if you want to save the file in the web server */

$filename = 'certificate_aadarsh.png';

ImagePng($image, $filename);

imagedestroy($image);

 

 

/* If you want the user to download the file */

$filename = 'certificate_aadarsh.png';

ImagePng($image,$filename);

header('Pragma: public');

header('Cache-Control: public, no-cache');

header('Content-Type: application/octet-stream');

header('Content-Length: ' . filesize($filename));

header('Content-Disposition: attachment; filename="' .

 basename($filename) . '"');

header('Content-Transfer-Encoding: binary');

readfile($filename);

imagedestroy($image);
