You need to get PHP to set the Content-Type to text/html. Otherwise, mod_pagespeed won't even be called for that file.

It should work with PHP files that generates HTML, as long as the HTML is marked with content-type: text/html.

Some other users have fixed this by adding

in pagespeed.conf

AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER application/x-httpd-php

(Note: This will try to parse all files of type application/x-httpd-php as HTML.)

or

SetOutputFilter MOD_PAGESPEED_OUTPUT_FILTER

(Note: This will replace all other OutputFilters you may have set and will try to parse everything as HTML.)

Actually, the right way to do this is probably to setContentType in PHP:

http://php.net/manual/en/function.httpresponse-setcontenttype.php

Let me know if that works.

none of the options work properly.
A simple example ... I created a index.html file and works correctly when I change the extension to php module does not recognize the content-type text/html even though the output of it php is text/html

Did you try using PHPs setContenType?

We have seen this issue several times on the list and generally the issue is that webmasters are setting headers with mod_headers instead of in mod_php. mod_headers runs after mod_pagespeed (and after the contents have been compressed, etc.) so we cannot see the results of that filter.

Hm, that's very strange. Thanks for testing that with mod_headers explicitly disabled.

Do you get anything in your Apache logs that might be relevant? Specifically, do you get any mention of index.php from mod_pagespeed logs?

When I get a chance I'll try setting up a default Ubuntu machine with mod_php and mod_pagespeed to test this myself.

Ah, also, mod_pagespeed will only rewrite a file if it's first char is a "<"

It appears your file is:

Hello

Can you change it to:

<html><body>Hello</body></html>

or something similar?

Alright, I fired up fresh Ubuntu 10.04 32bit machine and this worked fine for me.

Here's what I did:

$ sudo apt-get install apache2 php5 libapache2-mod-php5

$ sudo dpkg -i mod-pagespeed-beta_current_i386.deb

$ sudo apt-get -f install

$ sudo /etc/init.d/apache2 restart

$ cat /var/www/test.php

<?php

header('Content-Type: text/html')

?>

<html>

<body>

<p>Hello, world!</p>

<?php echo "<style> p { color: blue; } </style>"; ?>

</body>

</html>

$ curl -v http://172.25.36.185/test.php

Notice the X-Mod-Pagespeed header was added and <style> was rewritten.

Is this comparable to what you did? I know you are using Ubuntu 11.10, but that shouldn't make much of a difference.

Can you try using the header() function? I couldn't get HttpResponse::setContentType() to work.

Hi,

I’m also new to using mod_pagespeed and I’m trying to get it to work with my PHP site. I tried Shawn’s example below and it worked exactly as he said it should (so it is installed on my server correctly).

I’m testing it against my index.php and while it is ‘optimizing’ it, I’m actually seeing only a marginally better performance and I’m not sure why that’s happening.

Can you send a URL? There are many reasons that it might not optimize your site much.

Kinda crazy – but I switched it on about an hour back and restarted apache, but I only see it working on the subdomains, but not the main www one! See: http://test1.lildevelops.com/

I guess the problem is different from what I initially thought it was – mod_pagespeed is working fine on the subdomains (and being effective), but not all on the main www domain.

Do you have any idea why that might be happening?

S,

Thank you for clarifying what the problem is. I think we're on the same page now.

Unfortunately, we can't help you figure out *why* it's happening without some more information.

Could you please send your pagespeed.conf file? Could you also please send your error logs?

Thanks!

Howdy,

Your pagespeed.conf doesn't reveal anything. The only guess I have is that for some reason where you are serving the content from is causing the differences ... but I can't think of a reason as to why. If you can send me your entire log (or at least a large section including mod_pagespeed messages) that might help. But I really have no idea why this would be working for one vhost but not others.

Acutally, just to check, you are running these sites as multiple vhosts on one Apache config, right? Where do you include the pagespeed.conf file? In the main config or in the vhosts themselves? This may just be a vhost configuration issue ... maybe.

There are some error messages being generated which look like this:

[Tue Dec 06 06:37:55 2011] [error] [mod_pagespeed 0.9.18.7-900 @28011] /var/www/mod_pagespeed/cache/sX0sHMkrUWR7DPcapcOS.lock:0: failed to stat (code=2 No such file or directory)

All of them are similar – the only change in all these lines is the datetime, the number after the @, and the filename.lock.

Viewing it in context of the surrounding lines, I think its happening because of an unrelated issue in our mod_rewrite rules wherein files are being searched for in folders which do not exist.

>>> Acutally, just to check, you are running these sites as multiple vhosts on one Apache config, right? Where do you include the pagespeed.conf file? In the main config or in the vhosts themselves? This may just be a vhost configuration issue ... maybe.

Yep – these sites are multiple vhosts within on Apache’s httpd.conf file. I’m not sure how the two are linked – I installed mod_pagespeed and didn’t do anything after that.
