problem with http REQUEST

[federik]

hi. i've got this problem:
in my php script i need to get a param passed with the url.

i use this: $string=$_REQUEST['param name'];

it works, but my problem is that in cases linke this:

page.php?param="aaa&g=bbbb"

i want to get the full param while the code above takes just the param until the first "&".

can you help me?

use [man]urlencode[/man] when you echo the link:

echo 'page.php?param='.urlencode('"aaa&g=bbbb"');

[federik]

i need to take th param passed to the page, i don't need to echo it!

wilku didn't show you how to echo it, he suggested you to use [man]urlencode[/man] ...

Just to clarify, the query string portion of page.php?param="aaa&g=bbbb" is invalid, as any special charcters such as the "&" must be specially encoded if it is not to have its special meaning of being a variable/value pair separator. Thus the suggestion that you uses urlencode() when creating the original link, so that it is correctly encoded and will therefore treat that whole string a a URL query string value.

Indeed, I suggested making the link valid. If the link wasn't created by you and you have no influence over its making you can parse query string yourself. The query string should be stored in $SERVER somewhere ($SERVER['QUERY_STRING'] or sth similar, I don't remember exactly). You can match the query with [man]preg_match[/man] and regular expression like '/param="(.*)"/'.
