[英]Regex : Removing all extra whitespace, line-breaks, and empty spaces
Update: It seems like it is just a regex problem. 更新:看来这只是一个正则表达式问题。
I am trying to remove all extra whitespace, line-breaks, and empty spaces from user story with a function to grab only 100 characters 我正在尝试使用仅捕获100个字符的功能从用户故事中删除所有多余的空格,换行符和空白
Issue is although 100 character limit works, the removing of whitespace, linebreaks and empty spaces does not apply: 问题是,尽管可以使用100个字符的限制,但是空格,换行符和空格的删除不适用于:
function aboutme_echo($x, $length)
{
if(strlen($x) <= $length)
{
echo $x;
}
else
{
$y = substr($x,0,$length) . '...';
echo $y;
}
}
aboutme_echo((preg_replace("/\s+/"," ", $aboutme)), 100);
Example String: 🤣🤣🤣WHAT?! 示例字符串:🤣🤣🤣WHAT?! That's crazy!
太疯狂了!
Long story short, 长话短说,
😛😛someone reached out to me who had a pharma virus. 😛😛有人联系我,发现有人感染了药草病毒。 😎I have the opportunity to rebuild their site, but I can't rush the planning and staging, but i...
😎我有机会重建他们的网站,但是我不能匆忙进行计划和分期,但是我...
Something like this maybe? 像这样的东西?
function cleanExcerpt($string) {
$pattern = '/\s+/';
$replace = ' ';
$cleanstring = trim(preg_replace($pattern,$replace,$string));
return strtok(wordwrap($cleanstring, 100, "...\n"), "\n");
}
To use, you must pass through a string and echo the function like this: 要使用它,您必须传递一个字符串并回显如下函数:
$string = "Example String: 🤣🤣🤣WHAT?! That's crazy! Long story short, 😛😛someone reached ";
echo cleanExcerpt($string);
