 Posted: Thu 30 Oct '14 22:35 Post subject: Cyrillic characters in URL string are not visible in $_GET |
 |
|
Hello, everybody!
I've migrated from Apache 2.2 to Apache 2.4 few days ago. It is installed as a service on my Windows 7 developer machine and works in bundle with PHP 5.6.2.
Today I've discovered that GET parameters with Cyrillic characters in URL string are empty.
For example URL looks like this: site.com/search.php?q=%C8%E2%E0%ED%EE%E2
URL-encoded string here is Иванов (%C8%E2%E0%ED%EE%E2)
When I try to use this GET parameter in my PHP script - the variable $_GET['q'] is empty. If I put latin characters in this parameter - $_GET['q'] is taking the corresponding value.
Doesn't look like it's a problem of PHP as I think. Otherwise at least something should stay in the variable.
And also I would like to add that this was working absolutely normal on Apache 2.2.
I will appreciate any suggestions on my issue. |

Did you try a print_r($_GET) ?
Did you install any filtering like mod security? |

Hi, Mr. Blond 
Thanks for the reply. Yes, I've tried to print the GET array. Latin values are present in it, Cyrillic - empty. No additional mods were installed. Checked this also in httpd.conf. |

Well the url encode is not correct. it should be
%D0%98%D0%B2%D0%B0%D0%BD%D0%BE%D0%B2
With that my test script runs well
| Code: |
header("Content-Type: text/html; charset=utf-8");
print_r($_GET);
echo urlencode($_GET['q']);

Didn't get why it's incorrect. There are 6 letters in Иванов and in your string %D0%98%D0%B2%D0%B0%D0%BD%D0%BE%D0%B2 encoded 12 characters.
Anyway this doesn't matter. No matter how much Cyrillic characters I'll put in $_GET['q'] via URL, it will be still empty. Could this be due to CP-1251 charset I'm using? |

I use ANSI or UTF-8 as charset for the document (file) so save it.
Did you change anything in apache charset or PHP charset? |

In httpd.conf there's: AddDefaultCharset UTF-8
In php.ini all the charset lines are commented. |

There's one more interesting finding: when I type Иванов directly to the browsers' address string (for example: site.com/index.php?q=Иванов) in GET variable q I get: Р�ванов
If I convert this string from CP1251 to UTF-8 it would be almost normal: ��ванов |

Oh god, I am extremely sorry for all this stuff. The problem was in my function that filters all coming data from user. I can't even imagine that it was doing this cuz' it works just fine on Debian server. But when I've commented the line calling this function here, on local machine all the Cyrillic data appeared on it's place. I apologize for this mistake and taking your time   |

Make sure you set the correct meta type
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
in doubt you can force it on the form tag with accept-charset |
