Add a prefix to each item of a PHP array

I try to use Boolean mode full text search.

If a user types more than two words, it supposes to make like this.

Search Keyword :   Apple Macbook Air 

Result :   +Apple +Macbook +Air

So, I made a php command to make this happen, but didn’t work.

$ArrayKeywords = explode(" ", $b_keyword);
for($i = 0; $i < sizeof($ArrayKeywords); $i++)
$array_keyword = '+"$ArrayKeywords[$i]" ';

can you tell me how to make this happen?

Answer 1

Can also do (demo)

echo preg_replace('(\w+)', '+$0', 'Apple Macbook Air');
