How to have apostrophes in PHP string?

问题

Part of my PHP code includes the construction of a URL string as follows:

$msg = $_REQUEST["msg"];
$content =  'action=sendmsg'. 
                '&user='.rawurlencode($username). 
                '&password='.rawurlencode($password). 
                '&to='.rawurlencode($destination). 
                '&text='.rawurlencode($msg);

When $msg happens to contain an apostrophe, it get sent as "\'".

What do I need to do to make sure the backslash is not inserted by PHP?

回答1:

You probably want to check out stripslashes: http://php.net/manual/en/function.stripslashes.php

回答2:

Assume you want to send the $content variable instead of just stripping the backslashes, Consider to use urlencode() instead of rawurlencode(). Also, you can use the function once for your $content variable.

$content = urlencode($content);

UPDATE: both urlencode and rawurlencode may not fit your case. Why don't you just send out the $content without URL encode? How do you send our the query string? If you are using cURL, you do not need to encode the parameters.
