我需要动态创建一个图像,然后通过电子邮件发送给该人.这是图像创建脚本:

//Get the blank coupon
$rImg = ImageCreateFromJPEG('coupon.jpg');

$color = imagecolorallocate($rImg, 0, 0, 0);

imagestring($rImg,5,135,140,'$first_name', 'black');
imagestring($rImg,5,135,160,'$last_name', 'black');
imagestring($rImg,5,135,180,'$email_address', 'black');

从那里我想拍摄该图像并通过电子邮件发送给该人.我可以将其包含在电子邮件的附件中,还是实际上必须将其写入服务器？

我试过这样做:

function email_coupon($first_name, $last_name, $email_address){
//Get the blank coupon
$rImg = ImageCreateFromJPEG('coupon.jpg');

$color = imagecolorallocate($rImg, 0, 0, 0);

imagestring($rImg,5,135,140,'$first_name', 'black');
imagestring($rImg,5,135,160,'$last_name', 'black');
imagestring($rImg,5,135,180,'$email_address', 'black');

//define the receiver of the email
$to = '$email_address';
//define the subject of the email
$subject = 'Your coupon';
//create a boundary string. It must be unique
//so we use the MD5 algorithm to generate …

查看PHP脚本运行所需时间的最佳方法是什么？

我在想这样的事情:

$start_time = time(); //this at the beginning
$end_time = time(); //this at the end
echo = $end_time-$start_time;

但是我怎样才能把它变成对我来说可读并对我有意义的东西呢？
