PHP Conditional Replace

[danIT]

Need a little help, i'm by now means literate in PHP but here goes:

 

$tag=$_GET['tag'];

if($_GET['tag']==''){

$tag = 'Search...';}

if (!isset($_GET['maxpages']))
{
$max_pages = 20;
}else
{
$max_pages = $_GET['maxpages'];
}
if ($max_pages > 50)
{
die("No way am i doing more than 50 pages. Sorry mate.");
}
?>

 

I use a form to take $tag and stick it on the end of a url:

 

http://search.twitter.com/search.atom?&q={$tag}

 

Its basically a Twitter search script, the trouble i having is if $tag contains a #, kinda vital to a twitter search.

 

I think whats happening is this:

 

$tag = #edugeek

 

- Twitter Search%23edugeek

 

I think twitter needs to get #edugeek not %23edugeek

 

How can I change my script so that if $tag starts with # or contains # it is correctly sent to twitter?

 

To test I replaced %23 to # in the browser and it works, just need the script to do it now!

PHP: urldecode - Manual

 

UrlDecode, this will change %23 to # within your string

 

 

$tag = urldecode($_GET['tag']);// should work or, $tag = $_GET['tag'];$tag = urldecode($tag);

if($_GET['tag']==''){

$tag = 'Search...';}

if (!isset($_GET['maxpages']))
{
$max_pages = 20;
}else
{
$max_pages = $_GET['maxpages'];
}
if ($max_pages > 50)
{
die("No way am i doing more than 50 pages. Sorry mate.");
}
?>

Superb, thats exactly what I needed....

 

Well almost, I got the problem wrong... I needed to Encode the # not decode

 

Ta!

That'll be PHP: urlencode - Manual then...

Sidenote:

 

I also generate a .csv of the search to download, anyone know how I might store this on the server once generated?

 

A colleage did tell me the name of a function but cant for the life of me remember? Think it began with S?

Probably fopen(), fwrite() and fclose().
