PHP Header() help...

[JoeZ]

so I'm trying to do a dynamic redirect using a variable...

This works:
header ("Location: http://asseeeiffs.com");

This doesn't:
$url = http://asseeeiffs.com;
header ("Location: $url");

It sends to literally "$url" and throws a 404, instead of the value of $url.

Any help is appreciated.

 

[I_like_cock]

$url = "http://msn.com";
header ("Location:". $url);

Brilliant!

I suspect in your original you had single quotes instead of double quotes. I've made that mistake in the past.

 

[JoeZ]

working version has single...as far as I can tell they are interchangable

 

[argh01]

Nope.
When you use single quotes, it doesn't replace variables. So

$foo='bar';
print '$foo';

prints '$foo'.

Good for dollar amounts but not so good for printing 'bar'.
It's one tip for making your code faster; if you have a block of text with no variables to assign to another variable, use single quotes and php won't evaluate it for variables which takes valuable microseconds.

ah thanks...didn't know that.

Got another quick question while you are here...

Any idea why a cookie would work on one system and not another when the person it isn't working on tells me their cookies are enabled and work?

 

[argh01]

ahh, no?
What's the cookie?
What code are you using?
What site is it on?

 

[JoeZ]

prob easier to talk on AIM if you don't mind....


setcookie("uniqueid", $id); //sets cookie
$id = $HTTP_COOKIE_VARS["uniqueid"]; //reads cookie

worked for 2 people, didn't for one

 

[JoeZ]

Oddly enough, I just tested this test.php page and it worked upon refresh perfectly on all variables...

<?php
$name = "Success!";
setcookie("id", "", time()-300000);
setcookie("id", $name);
echo $HTTP_COOKIE_VARS["id"];
echo "<-One <br>";
echo $_COOKIE["id"];
echo "<-Two <br>";
echo $id;
echo "<-Three";
echo "<br><br>";
print_r($_COOKIE);

?>

 

[JoeZ]

bump.

 

[argh01]

looks fine; does the person it didn't work for refuse your cookie ? Other than that, donno.

 

[JoeZ]

No...the person is a close friend so I know they weren't messing with me. That script worked, but using the same code in my real script didn't work. The setcookie didn't seem to work in the real script, but did in the test..
