我正在使用此脚本来简单地从文本创建图像.我想知道的是如何保存图像而不是直接打印到浏览器;
// an email address in a string
$string = $post[$key];
// some variables to set
$font = 4;
$width = ImageFontWidth($font) * strlen($string);
$height = ImageFontHeight($font);
// lets begin by creating an image
$im = @imagecreatetruecolor ($width,$height);
//white background
$background_color = imagecolorallocate ($im, 255, 255, 255);
//black text
$text_color = imagecolorallocate ($im, 0, 0, 0);
// put it all together
$image = imagestring ($im, $font, 0, 0, $string, $text_color);
任何帮助将非常感谢,问候,菲尔.

我试过以下但只是得到一个黑色的盒子;
// an email address in a string
$string = $post[$key];
// some variables to set
$font = 4;
$width = ImageFontWidth($font) * strlen($string);
$height = ImageFontHeight($font);
// lets begin by creating an image
$im = @imagecreatetruecolor ($width,$height);
//white background
$background_color = imagecolorallocate ($im, 255, 255, 255);
//black text
$text_color = imagecolorallocate ($im, 0, 0, 0);
// put it all together
imagestring ($im, $font, 0, 0, $string, $text_color);
imagepng($im, 'somefile.png');
imagedestroy($im);
解决方法:
imagepng($image, 'somefile.png');
