[Function] PHP Phrase Highlighter

[LordDan]

Hey!

Been away from PHP for a few weeks and cannot bare it any longer so I had to type something!

Anyway, I decided to write a quick Search Phrase Highlighter.

PHP:

function highlight_words( $string, $words, $color = '#FFFF99' ){
   $words = ( is_array( $words ) ) ? $words = implode( '|', $words ) : $words;
   return preg_replace( '@\b('. $words .')\b@si', '<span style="background-color:'. $color .'">$1</span>', $string );
}

 

Usage:

echo highlight_words( 'This is my string ya\'know!', 'my' ) .'
';
echo highlight_words( 'This is my string ya\'know!', array('my', 'this'), '#99FFCC' );

 

Result:

Hope you find use of it ^^

This could be quite useful actually, I like it.

Make a search feature and it highlights the words the user input.
