Question

PHP 中是否有一种方法来计算字符串给定宽度和给定行距的线条?

For example, if I have this text:
Sed eget lorem lorem. Pellentesque tristique, quam vel fringilla porttitor,
neque elit suscipit nisl, id posuere magna libero congue ante.
= 2 lines

Sed eget lorem lorem. Pellentesque
tristique, quam vel fringilla
porttitor, neque elit suscipit nisl,
id posuere magna libero congue ante.
= 4 lines because the width is not the same

Edit: My question was not clear.
As Jason McCreary said, I want to create a formula (based on font-size, string length, line-height) with PHP that will get me close.

如果有人能派我走正确方向去做我很感激的事因为我试图创造那个神奇的公式却毫无结果

我无法在页面中使用 JavaScript 。

谢谢!

Answer 1

最后,这就是我所做的:

$charWidth = 5.6;
$divWidth = 550;

$wrappedContent = wordwrap($originalContent, ($divWidth / $charWidth), "
");
$explodedLines = explode("
", $wrappedContent); 
$nbOfLine = count($explodedLines);

echo $nbOfLine;

没有必要说这是非常接近的。

Answer 2

否。 PHP 是服务器的侧面技术。它不知道 HTML 生成的结果。

相反,你可以:

Use JavaScript. It s a client side technology and will provide much better results.
Create a formula (based on font-size, string length, line-height) with PHP that will get you close.

Update

勾选以下函数 : < a href=" "https://www.php.net/strlen" rel="nofollow noreferr"\\ code>strlen () 和substr_count () 以帮助您启动 PHP 公式。它们会帮助您使用行长度和行数。行宽和字体大小应该保持不变。

Answer 3

只能用 CSS 就可以了

<div style="width: 10em; height: 1.2em; overflow: hidden; text-overflow: ellipsis;">
Now a long woooooooooooooooooooooooooooooooord
</div>
