在第一个单词后的所有文本周围包装HTML标签

Question

How can I rewrite this code such that it wraps html tags around the last words after the first word;

preg_replace('/(?<=\>)\b\w*\b|^\w*\b/', '<span class="color_red">$0</span>', $atts['title']);

At the moment this regular expression will wrap tags around the first word in a string. I have tried this but it does not work;

preg_replace('/(?<=\>)\b\w*\b|^\w*\b/', '<span class="color_red">$1</span>', $atts['title']);

Here are some examples;

Efficiency <span class="color_red">solutions</span>
Renewable <span class="color_red">Energy Solutions</span>
Accidentally <span class="color_red">left the caps lock on and typed something</span>

Or please provide another solution that works.

Answer 1

To match everything after the first word until the last non white space

preg_replace('/\b[\w\'-]+\W+\K.*\S/s', '<span class="color_red">$0</span>', $atts['title']);

• \\b matches inital word boundary of first word
• [\\w'-]+ one or more word characters , single quote and hyphen in a character class
• \\W+ one or more non-word characters
• \\K resets beginning of the reported match
• .*\\S anything until the last non white space character
• s - flag for making the dot match newlines
• if input is utf-8, add u flag for unicode regex to adjust \\b , \\w , \\W

You can do it with this way also..

$data = "Write your description here";
list($first,$last) = explode(" ", $data,2);
echo $newstring = $first." <span>".$last."</span>";
