title: error: php.h no such file or directory
body: <p>I am working with the following tutorial: <a href="http://abhinavsingh.com/blog/2008/12/php-extensions-how-and-why/" rel="nofollow">http://abhinavsingh.com/blog/2008/12/php-extensions-how-and-why/</a></p>
  
  <p>I did create in a folder the <code>php_sample.h</code> file. I have an error: <code>php.h no such file or directory.</code> I've installed <code>php and apache using apt-get install.</code> SHould i import in my file <code>php.h</code> ? I also don't know where to look for config.m4. I've searched in usr/lib/php5 but i didn't find it. In <code>usr/local</code> there is no appache folder. Need some tips. Thx! Appreciate</p>
  
  <p>I would like to mention that i am working in ubuntu 10.10. I've tested a simple <code>.php code</code> after adding it in <code>/var/www</code> and it works.</p>
