什么是显示加下划线的文本和输出其结果作为与GD或任何其他库图像的最佳方法?

有帮助吗?

解决方案

可以尝试使用Unicode下划线组合字符U+0332

<?php
// Set the content-type
header('Content-type: image/png');

// Create the image
$im = imagecreatetruecolor(400, 30);

// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);

// The text to draw
$text = "&#x0332;U&#x0332;d&#x0332;e&#x0332;r&#x0332;l&#x0332;i&#x0332;n&#x0332;e";
// Replace path by your own font path
$font = 'arial.ttf';


// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>
