- Language:: PHP

Sometimes, for example, when displaying search results, it is a great idea to highlight specific words. This is exactly what the following function can do:
`1.``function` `highlight(``$sString``, ``$aWords``) {`
`2.``if` `(!``is_array` `(``$aWords``) || ``empty` `(``$aWords``) || !``is_string` `(``$sString``)) {`
`3.``return` `false;`
`4.``}`
`5.`
`6.``$sWords` `= implode (``'|'``, ``$aWords``);`
`7.``return` `preg_replace (``'@\b('``.``$sWords``.``')\b@si'``, ``'<strong style="background-color:yellow">$1</strong>'``, ``$sString``);`
`8.``}`Source: http://www.phpsnippets.info/highlights-words-in-a-phrase
