有人能解释一下如何创建图像与数字，我得到这个查询:
$sumq = mysql_query("SELECT SUM(count) FROM downloads");
$row1=mysql_fetch_array($sumq);
您可以使用imagestring:
<?php
$text = 42; // whatever your number is
// Create a 100*30 image
$im = imagecreate(100, 30);
// White background and blue text
$bg = imagecolorallocate($im, 255, 255, 255);
$textcolor = imagecolorallocate($im, 0, 0, 255);
// Write the string at the top left
imagestring($im, 5, 0, 0, $text, $textcolor);
// Output the image
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>
