问题描述
我的问题是,如何在图像中的所有文本下划线?
代码:
function createImage($text)
{
$text .= "\n";
$text = wordwrap($text, 40, "\n");
$newlines = substr_count($text, "\n");
if($newlines == 0)
{
$height = 30;
}
else
{
$height = 30*$newlines-$newlines*7;
}
putenv('GDFONTPATH=' . realpath('.'));
header('Content-Type: image/png');
$im = imagecreatetruecolor(315, $height);
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
$purple = imagecolorallocate($im, 97, 26, 139);
imagefilledrectangle($im, 0, 0, 399, $height, $white);
$font = 'arialbd.ttf';
imagettftext($im, 11, 0, 10, 20, $purple, $font, $text);
imagepng($im);
imagedestroy($im);
}
createImage("Stackoverflow Stackoverflow Stackoverflow Stackoverflow Stackoverflow Stackoverflow Stackoverflow Stackoverflow Stackoverflow Stackoverflow Stackoverflow Stackoverflow ");

我希望所有文本都带有下划线,我找到了一些解决方案,但它们只是从左到右,而不是取决于单词.

I want all the text to be underlined, I've found some solutions but they're only from left to right, not depending on words.
推荐答案
使用结合字符U + 0332的Unicode下划线.
Use the Unicode underline combining character U+0332.
您将需要循环或巧妙地合并数组以修改文本,
You will need a loop to or clever array merge to modify the text,
$e = explode(' ', $text);
for($i=0;$i<count($e);$i++) {
$e[$i] = implode('̲', str_split($e[$i]));
}
$text = implode(' ', $e);
