缩短PHP中的文本字符串 [英] Shorten a text string in PHP

问题描述

有没有一种方法可以在PHP中修剪文本字符串，使其具有一定数量的字符?例如，如果我有字符串:

Is there a way to trim a text string in PHP so it has a certain number of characters? For instance, if I had the string:

$string = "this is a string";

我怎么剪成这样:

$newstring = "this is";

这是我到目前为止使用chunk_split()所获得的，但是它不起作用.谁能改善我的方法?

This is what I have so far, using chunk_split(), but it isn't working. Can anyone improve on my method?

function trimtext($text)
{
$newtext = chunk_split($text,15);
return $newtext;
}

我还查看了这个问题，但我不太了解.

I also looked at this question, but I don't really understand it.

推荐答案

if (strlen($yourString) > 15) // if you want...
{
    $maxLength = 14;
    $yourString = substr($yourString, 0, $maxLength);
}

会做.
