extracting from a string

mmilano

http://www.google.com/search?q=prin...8&start=10&sa=N

that is the result of an $_SERVER['HTTP_REFERER'] variable. i'm trying to extract the search string. everything between "q=" and "&"

i notice that in some strings, the end of a google refer could end with the end of line also

sooo .. i need to extract between:
q= and &

q= and (end of line)

the idea here would be that i could do something like this:


do you think this can be done with string functions? or is it more of a job for regex?

well here is a long way 🙂

<?
$string = "http://www.google.com/search?q=prin...8&start=10&sa=N";
$var = explode("&", $string);
print $var[0]."<br>";
print $var[1]."<br>";
print $var[2]."<br>";
$var2 = explode("?", $var[0]);
print $var2[0]."<br>";
print $var2[1]."<br>";
?>

maybe this is an easier way?

http://us2.php.net/function.parse-url

something like this:

$string = "http://www.google.com/search?q=prin...8&start=10&sa=N";

$url=parse_url($sting);
echo $url[query]; //should output q=prin...8&start=10&sa=N

good luck.

edit: now that i look at my response, it would only help from q to end of line, but using the previous post code it should be enough.
