将特殊字符插入到Web地址的字符串中（PHP问题）

Question

I posted this question last week, but I wasn't very clear on what was needed. So I'm reposting right now.

I have a string stored in a database, which looks something like this:

<5u79cfda 4d01ga3a 11c833f9 7b52df2a 7g210252 e21b01fa a73d3463 9ge0e412>

I'm trying to insert this into a web address, but needs to be encoded properly for it to work. I'm running a query to obtain the script:

$result = mysql_query("SELECT cPushID FROM tblUsers WHERE intUserID='20' AND Length(cPushID) > 70");

$pid = mysql_fetch_row($result);

Then trying to insert it into this web address to be executed:

file_get_contents("http://domain/test.php?msg='Test!'&to=$pid");

How do I properly insert this string into the web address so it will be read properly upon execution.

Thanks for your help.

How about urlencode?

$encoded = urlencode($some_string");

Pass that encoded string to file_get_contents

If you ever need to decode it, use urldecode()
