[SOLVED] Script working, but is there a better way?

[NevadaSam]

 

With this script I get the desired results of: Search words used: A big fast red truck

 

But I was wondering if there is a better way.

 

$str is received from a search form. A lot of other code not shown here removes all words less than three characters, because they are not use in a mysql search. This script echos all the words the user submitted with the words that were actually used in bold. Could I have done this better?

 

<?php
$str = "A big fast red truck";
$searchwords = preg_replace( '#(\b[\w]{0,3}\b)#', '', $str ); // removes <=3 char words
$searchwords = preg_replace('/\s+/', ' ', $searchwords); // removes extra spaces
$searchwords = explode(' ', $searchwords);
array_walk($searchwords, create_function('&$v, $k', '$v = "/\\b$v\\b/i";'));
$str = preg_replace($searchwords, '<strong>\\0</strong>', $str);
echo "Search words used: " . $str;
?>

Seems pretty solid to me, as long as it is working and working well, no need to change it.

 

The only part I wonder about is where you "Remove" the extra spaces and than you explode by the space...wouldn't you rather use the www.php.net/trim function to handle that part if you are just removing extra spaces at the beginning and end of the string?

 

Either way seems pretty solid.

Maybe this is not so much code:

<?php
$str = "A big fast red truck";
$str = preg_replace('/([\w\d]{4,})/', '<strong>$1</strong>', $str);
echo $str;
?>

frost110: In my full code, I do use trim() to remove end spaces. while the beginning does not seem to be a problem, a space on the end will really mess it up. And I remove any extra spaces that may be between words along with comma, quotes, etc. In this small code it did not work right without removing extra white space. I think that was because when I remove 3 letter words only the text was taken out leaving the extra space that was with it. The actual input will come by a user via an input box so anything could happen.

 

Lumio: That may be a much better code. Looks like it should wrap words with 4 or more letters. I was going the long way around doing it backwards. I will try that.

 

Thanks to everyone who look and read.
