Php – mod_headers not sending headers when file is PHP

apache-2.2http-headersPHP

I've got my .htaccess file set to the following:

 Header set MyHeader "I'm Set!"

If I go to that directory (http://example.com/test/), which has no default index file, and view the network activity (in this case with Chrome), I can see that the header is being sent. If I go to a php file (http://example.com/test/test.php), the header isn't sent.

I've created an index.html (with simply <pre>Hi as the content) and it gets sent. I change the file name to .php, no header. If I change the orignal test.php to test.html, it outputs the garbage-looking code, and the header is sent. If I change test.php to test.png, I get a broken image icon, and the header is sent.

So, without testing beyond the above in terms of mime-type and file extensions, it appears only .php files (legit or otherwise) are either set to not have .htaccess rules apply or specifically the mod_headers directives. But I don't know how to test for this and because it's a shared server, I don't have httpd.conf access to poke around.

Any ideas as to why apache would skip sending headers for php files?

I've also tried:

 <FilesMatch "\.(php)$">
     Header set MyHeader "I'm Set!"
 </FilesMatch>

This is expected behavior when running CGI scripts. From the latest (2.4) version of the mod_headers docs:

The default value of onsuccess may need to be changed to always under the circumstances similar to those listed below. Note also that repeating this directive with both conditions makes sense in some scenarios because always is not a superset of onsuccess with respect to existing headers:

[...]
You're modifying or removing a header generated by a CGI script, in which case the CGI scripts are in the table corresponding to always and not in the default table.

The original issue (with, perhaps, a better explanation) is in Bug 49308.

Php – IIS/PHP/FCgi wrong setup – No page no error

I recently implemented a similar setup:

Windows Server 2003 Web Edition
IIS / FastCGI (http://www.iis.net/expand/fastcgi)
PHP 5.3.1 (installed via zip file into c:\php)

From my deployment notes, the install steps were:

Download PHP 5.3.1 zip (http://windows.php.net/download/, note the "Which version do I choose?" section)
Install into c:\php
Test php -v works on the command line (in c:\php)
Associate .php with FastCGI: IIS Manager -> machine -> Web Sites -> site -> right click, choose properties -> choose "Home Directory" tab, click "Configuration", Mappings tab. Config for .php looks like:

alt text

Configure FastCGI's config file (C:\WINDOWS\system32\inetsrv\fcgiext.ini) with at least:

    [Types]
    php=PHP

    [PHP]
    ExePath=c:\php\php-cgi.exe

Append/change the following to c:\php\php.ini. Without this config, my config bounces between giving blank pages and not loading at all (I guess this is your problem):

    fastcgi.impersonate = 1
    fastcgi.logging = 0
    cgi.fix_pathinfo=1
    cgi.force_redirect = 0

Set
```
display_errors
```
on in c:\php\php.ini and uncomment extension=php_mysql.dll.
Restart IIS for the site (click the stop/play buttons)

In this config, you've essentially got two components, the plumbing between IIS-FastCGI-PHP, and PHP itself. I'd recommend isolating which of these isn't working:

Temporarily edit fcgiext.ini and point the PHP ExePath to something different, e.g. c:\php\nothere.exe. If the server starts returning "The FastCGI executable could not be found" for PHP requests, then I'd FastCGI was working correctly, and PHP is at fault.
Run PHP with its default config, the fastcgi/cgi changes above and display_errors on. You'll need to restart IIS (and possibly kill off any php-cgi processes) for the site you're restarting for the changes to be recognised.
Run PHP on the command line with a simple phpinfo(); script, to check basic operation, and note where the loaded php.ini is. This checks a rogue config file (e.g. in c:\, c:\windows etc) is not being used.

These steps confirm (at least) the PHP executable is being invoked, with the most basic config.

Php – RegEx Match URL Pattern

What language are you using?

In general it sounds like you want something that matches the basic aspects of a domain, ruling out the possibility of a period other than the one that delinates the .tld.

#http://[^.]+\.(com|net|org)#i

If you don't want to match the protocal, maybe something like this.

#[^. ]+\.(com|net|org)#i

Your desire to handle multi-part TLD's will really screw this up, you will need to maintain a manual list of all the ones you want to match. The only alternative is to do DNS lookups to determine the listing type. There really isn't another way to extract subdomain data from the domain with a regular expression because by rights domains are actually just subdomains of some TLD (top level domain).

Edit: To match TLD's assuming they woudl have less than four characters, you can play around with something like this. You're going to have to work out what constitutes the start and end of a match. Are you requireing the presense of a protocal? Is this in a paragraph where somebody could type.a period out of context? If you give more details on the parameters we might be able to provide a more precise solution.
