Hey out there
Time for another script from me 
, well this one will allow you to search on Google using a class with some functions i've just finish putting together =)
Lets start out by making the class and then explain the functions and last some examples.
The Class:

?>Same that as what you like, i choosed "googlesearch.class.php".
Class functions
GoogleSearch::GoogleSearch($query, $start, $num, $safe, $spell, $local)
- $query = The query to be executed on Google
- $start = Where to start on listing results, default is 0
- $num = How many results per page, max 100. default is 10
- $safe = Enable google safe search, default is 0
- $spell = If you have used spell check on your results, then set this to 1 to prevent google from saying "Did you mean xxx?"
- $local = Local language you want to search on, eg. da for danish. default is 'en'
GoogleSearch::setQuery($query)
- $query = New query to be executed
- $local = New local area to search in
- $safe = Change google safe search method
- $start = New starting row to list results from
- $spell = Change google spell check from being used
- $num = Set how many results you want returned
GoogleSearch::getQuery()
- Returns given query string
- Returns given local area string
- Returns true if using Google safe search, false otherwise
- Returns on where to start listing results by
- Returns if you have disabled or enabled the spell check, true if enabled false otherwise
- Returns info about spelling (only if on, and what google suggest you could search on)
- Returns how many results you want per page
GoogleSearch::getAll()
- Returns all configuration variables set from the constructor/set functions
- $var = Variable to set (query, local, safe, start, spell or num)
- $val = New value
- Returns value of $var, given from the constructor/set functions
GoogleSearch::getSearchResults()
- Returns search results (First when you have "performed" a search)
- Returns the number of returned results
- Clear search cache
- Performs the search
The spell function (GoogleSearch::getSpellInfo()) will only return an result if you're on page on (mean you starting the search from $start 0, default), this function also returns an array. First array item ("spell") is set to true if google suggest something and the other array item ("item") is what google suggest you to search on. example:
<?php
// Assuming that $google is the an "GoogleSearch" Object and a
// search has been performed...
$spell = $google->getSpellInfo();
if($spell['spell'])
{
echo("Google suggest you to search on: " . $spell['item']);
}
?>Examples of usage:
A Normal standard search:
This small example is using the default search options set by the GoogleSearch::GoogleSearch() constructor function, we are searching on "Free ClanTemplates":
<?php
// Include class
require_once('./googlesearch.class.php');
// Construct
$google =& new GoogleSearch();
// Set query
$google->setQuery("Free ClanTemplates");
// Perform search
$google->performSearch();
// Run a loop and display the results
foreach($google->getSearchResults() as $result)
{
echo("
<p />
<div style=\"width: 600px;\">
<h3>" . $result['title'] . "</h3>
" . $result['description'] . "<br />
<a href=\"" . $result['url'] . "\" target=\"_new\">" . $result['url'] . "</a>
</div>
");
}
// Shutdown
$google = null;
?>Exampe output:

Search using google spell check (Remember you can set spell check off using GoogleSearch::setSpell() to 0):
An exampe showing how easy it is to use the Google Spell check, we search on "prodict" with 3 results:
// Include class
require_once('./googlesearch.class.php');
// Construct
$google =& new GoogleSearch();
// Set query
$google->setQuery("Free ClanTemplates");
// Set max results to 3
$google->setNum(3);
// Perform search
$google->performSearch();
// Run a loop and display the results
foreach($google->getSearchResults() as $result)
{
echo("
<p />
<div style=\"width: 600px;\">
<h3>" . $result['title'] . "</h3>
" . $result['description'] . "<br />
<a href=\"" . $result['url'] . "\" target=\"_new\">" . $result['url'] . "</a>
</div>
");
}
// Spell check
$spellinfo = $google->getSpellInfo();
if($google->getStart() == 0 && $spellinfo['spell'])
{
echo("
<p style=\"border-top: 3px solid #000000;\">
<span style=\"color: red;\">Did you mean: " . $spellinfo['item'] . "?</span>
");
}
// Shutdown
$google = null;
?>Note that the Spell thing isnt working very well, so it might give lots of errors, my suggestion until I come out with a new version that fixes this is to not using it
Cheers,
Kalle
