HELP - Pretty simple PHP Question

I have a pretty simple question about PHP that I hope you'll be so kind as to help me out with.

Basically, I'd like to be able to echo the text after a "?" mark on my page from the URL.

So, if a user types in http://www.digitalpoint.com/?hey there

I'd like to be able to display the words "hey there" on the page, or anything else that follows the "?" I've tried a script for doing this, but it treats all spaces like it would a URL, it shows "hey%20there", instead of "hey there".

I much appreciate any help you can give, thank you very much in advance.

 

hmm... Don't know if that's possible.

try to print_r($_GET)

 

I'm sorry I'm pretty new to this, I don't really know what you mean by that.

 

you could make it easier on yourself. Make the urls print out liek this:

www.mydomain.com?v=hey_there

You can change the v= to whatever you like, just remember what it is, you can also if you like add in other variables:

www.mydomain.com?v-hey_there&y=hey_back

Then to echo out these into your content, you simply need to add:

print($_GET[v]); //which will print hey_there
print($_GET[y]); //which will print hey_back

Code (markup):

The above replies function print_r($GET); is a function to print the contents of an array (the array being between the brackets, and in theis instance the $_GET variables which is the name given to variables contained inside the url)

Hope that helps.

 

The way the information is posted to the server by the URL is this: http://domain.ext/?name=value

There is an easy way to redirect all your /?hey there requests via the mod_rewrite. Just add this rule in your .htaccess file in the root of your domain:

RewriteRule ^domain\.ext/\?([a-z]+)$ /hi.php?name=$1

Where hi.php is the file you use to echo the text. Your visitors will see the URL: http://domain.ext/?sterex however, all the action will be happening at 'hi.php?name=sterex'

 

Put this into a file:

<?
foreach ($_GET as $key=>$value) {
	echo $key;
}
?>

PHP:

E.g. if you put it into text.php, you can do it with text.php?hey

Try it yourself: http://pastedrop.com/hey.php?hello

 

BEAUTIFUL!!!! You've saved my life man. Or solved a very frustrating problem for me. Same difference. Thank you.

 

Yeah, but if you want to do it a shorter way, without an equalization mark, use the code I wrote in #6.

With logondotinfo's code, you have to use e.g. ?text=hello, with mine, you can do it with ?hello

And you shouldn't use print($_GET[v]); too, use

echo $_GET[v];

PHP:

instead.

 

I'll try both ways, whichever one works best. At least I know I've got this problem solved =D.

 

P.S.
If you just want to get the stuff after the ? use $_SERVER['QUERY_STRING'];

That would give you hey there out of http://domain.com/index.php?hey there

 

$_SERVER['QUERY_STRING'] will do

 

I tried this one, but it adds an underscore between each word, eg "hey_there"

I'm correctly trying all suggestions, thanks.

 

i learned php on here tizag.com/phpT/forloop.php

hope that helps

 

<?php
$word= explode("?", $_SERVER['REQUEST_URI']);
$word = $word[1];
echo $word;
?>
Try this

 

<?php
$word= explode("?", $_SERVER['REQUEST_URI']);
$word = urldecode($word[1]);
echo $word;?>
Better still if you have spaces then you will get urlencode, so urldecode it

 

<?
foreach ($_GET as $key=>$value) { 
echo str_replace("_","",$key);
}
?>

PHP:

 

<?
foreach ($_GET as $key=>$value) {
echo str_replace("_"," ",$key);
}
?>
You would have to replace to "_" with " "

 

<?php
$word= explode("?", $_SERVER['REQUEST_URI']);
$word = urldecode($word[1]);
echo $word;
?>
This would take about half the time to process than the foreach

 

No, he don't. My code was 100% correct. He want's to replace _ with a line space. It does that. Test it yourself.

The correct code is still:

<?
foreach ($_GET as $key=>$value) { 
	echo str_replace("_"," ",$key);
}
?>

PHP:

 

Half the time of... 2 milliseconds?
