This is true, but the + itself should also be encoded.

I did a quick test, and when I post a form variable called test with a value of 1+1=2, the HTTP request looks like this:

POST /test.php HTTP/1.1
User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020916
Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,image/jpeg,image/gif;q=0.2,text/css,*/*;q=0.1
Accept-Language: en
Accept-Charset: ISO-8859-1, utf-8;q=0.66, *;q=0.66
Keep-Alive: 300
Connection: keep-alive
Content-Type: application/x-www-form-urlencoded
Content-Length: 14


So, that %2B would have to get decoded twice to result in a space.

Stan, do you have a way to see what the HTTP request is? You mention being on a BSD box, so I assume you have tcpdump? Also, is this behavior consistent with different browsers?

The plus sign is used to signify a space in some URL encoding. PHP is
probably thinking the text is encoded and it's removing the plus sign.
Not sure on a solution.

Subject: [PHP] Plus sign changing to space in html form

When i post a string containing plus sign with htmp form to a php scritp,

the '+' is changed to space. e.g: i enter 'as+df' to a text input but $_POST[] returns 'as df' instead.

It must be in php or apache configuration bcause i have this problem only

on sytem with FreeBSD. On windows it works as expected.

Know someone how could i make the '+' left intact? Please help.

echo $_POST['test'];
<form actiom='test.php' method=POST>
<input type=text value='' name=test>
<input type=submit value='submit'>
