I am struggling with ampersands in the query string.
file.php has only this line:
[code]
echo $_GET['var'];
[/code]


And the URL is http://domain.com/file.php?var=AT&T

Instead of echoing [b]AT&T[/b] the problem is that the script echoes only [b]AT[/b]

This also happens if the URL is http://domain.com/file.php?var=AT%26T

My configuration in server { ... } to handle PHP scripts is as follows:

[code]
location ~ .php$ {
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_pass backend;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/path/to/dir$fastcgi_script_name;
include fastcgi_params;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_intercept_errors on;
fastcgi_ignore_client_abort off;
fastcgi_connect_timeout 60;
fastcgi_send_timeout 180;
fastcgi_read_timeout 180;
fastcgi_buffer_size 128k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
}
[/code]

How to make this work?

this is normal because & is a separator in URL.

this should work. But this is a nginx question, not a FPM one. Please ask there.

btw which nginx version are you using ?

Here is the test I've just done:

test.php
<pre>
<?php var_dump($_GET); ?>
</pre>

calling http://foo.bar/test.php?var=AT&T outputs:

array(2) {
["var"]=>
string(2) "AT"
["T"]=>
string(0) ""
}

the & is not encoded, so it splits AT&T in two variables.

calling http://foo.bar/test.php?var=AT%26T outputs:

array(1) {
["var"]=>
string(4) "AT&T"
}

the & is encoded, so it doesn't split AT&T in two variables.

I'm using nginx 0.8.40 for this test with the following conf:
location ~ \.php2$ {
root html;
fastcgi_pass backend;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $request_filename;
include fastcgi_params;
}

nginx version is 0.7.65 and this is the output for nginx -V
[code]
nginx version: nginx/0.7.65

[/code]

For the URL index.php?title=D%26B the detailed log is at http://pastebin.com/ThgmBLGU

Never mind. This was a rewrite issue. The URL was not being rewritten correctly. This is solved now.
