Retrieve variable from url

Anon

Hey, I'm really new to php and I would like to know how to get the value of a variable "t" from a url that looks like this:

http://www.something.com/index.php3?t=sometext&f=othervariable

this is what I have so far but I get an error message

$a = split ('&', $query_string);
$i = 0;
while ($i < count ($a)) {
$b = split ('=', $a [$i]);
if urldecode ($b[0]) = 't' {
$tempText = urldecode ($b[1]);
}
$i++;
}

the error is:
Parse error: parse error, expecting `'('' in C:....

Thanks a bunch,
Randy

Simply refer to it with $t, $f, and so on...
and I believe the query string variable should be in caps: $QUERY_STRING

Hey, thanks for the help. worked great!

My suggestion: Read The Manual

Not to be sarcastic, but this a basic PHP feature that is well documented in the manual

Anon

I did look through the manual and that is where I got the code in my first post... where all the errors came from?

I do agree that the question was not that hard, I code in asp myself so I was not used to the syntax. But Max was nice enough to spot my mistake so thanks again Max!

Thanks,
Randy

I wasn't trying to put you down for asking a question. The way you presented your question lead me to think you had not even taken the time to look up the answer.

If you take a look at the variables section in the manual "variables from outside PHP", you will find a lot more info on gathering incoming data. This includes reading variables through arrays.

Soory if I had caused any offense

Sorry about getting a bit deffensive Darin... :o)

As a programmers I'm sure we all come across little problems that just stump us for hours and well, I've had other people just react negitively in the past to questions that have already been answered but that I was unable to find the documentation on.

Thanks again for the info of where to search in the manual. Happy PHPing!

Hey guys,

Here is my 2 cents. This form is what got me started on programming in Php and as a Java developer I gotta tell ya this forum is the BEST resource ive come across!(for any language) So personally I welcome any question be it in the manual or not. All I ask is try and after you fail and have learned somthing new you didn't know before then ask the forum.

Happy php'ing and ask away!
