Suggesting alternatives with search

closer2u

Need some help on this issue,

I want to incorporate some marketing in my site search engine by suggesting links (websites) when certain keywords are being used.

For example:

when a guest is searching the terms: "oil Alaska"

I want to add a suggestion link to www.alaskadate.com

So I need to tell php : if $query contains "Alaska" ... But I cannot seem to find the correct PHP commands for this...

Maybe first: eval $query ?

Any help is appreciated!

You just need to know if the word is a substring of the string, for that you can use [man]strpos/man, or in this case [man]stripos/man

If the searching needs to be more complex, regular expressions may be used, especially with [man]preg_match/man.

Thanks for your reply!

So something like:

<?php
if (preg_match("/alaska/", "$query")) {
   echo "www.alaskadate.com";
} else {
   echo "www.generalsponsor.com";
}
?>

yes, but strpos works for this example and is quite faster then a regular expression

Okay, checked that function with php.net and would make it like this?

<?php
$mystring = $query;
$findme  = 'alaska';
$pos = strpos($mystring, $findme);

if ($pos === false) {
   echo "www.generalsponsor.com";
} else {
   echo "www.alaskadate.com";
}

?>

Well, you could always try it, but yes; that should work.
