To see it in action, I have decided to do a quick benchmark. I have used the zf2 skeleton application, and my current zend framework 1.11 setting which I use in any of my PHP projects. The comparison is totally subjective and the aim is to have an overall impression.

I have used the apache benchmarking tool. The number of requests are 100 and the concurrency level is 5.
ab -c 5 -n 100 http://myUrl

Here are the results

Zend Framework 2

Server Software: Apache/2.2.20
Server Hostname: localhost
Server Port: 80

Percentage of the requests served within a certain time (ms)
50% 11
66% 12
75% 13
80% 14
90% 16
95% 23
98% 32
99% 33
100% 33 (longest request)


Zend Framework 1.11


Server Software: Apache/2.2.20
Server Hostname: localhost
Server Port: 80

Percentage of the requests served within a certain time (ms)
50% 17
66% 29
75% 33
80% 34
90% 40
95% 46
98% 51
99% 53
100% 53 (longest request)


Conclusion: New version of Zend Framework is nearly double times faster that the current version.

function getHeaders()
    {
        $headers = array();
        foreach ($_SERVER as $k => $v)
        {
            if (substr($k, 0, 5) == "HTTP_")
            {
                $k = str_replace('_', ' ', substr($k, 5));
                $k = str_replace(' ', '_', strtolower($k));
                $headers[$k] = $v;
            }
        }
        return $headers;
    }

P.S. If you have the possibility to use the mod_headers, than you’re free to use apache_get_headers() function.

Bu hatayı zend framework bir şekilde veriyor. Sanıyorum bir bug’dan kaynaklanıyor bu sorun. Yeni versionlarda bu hata giderilmiş olması lazım.  Lakin en kolay (geçici çözüm) ise aşağıdaki metodu Zend/View/Helper/Placeholder/Container/Abstract.php dosyasına eklemek.

Oh yeah.

/**
* Sort the array by key
*
* @return array
*/

public function ksort()
{
$items = $this->getArrayCopy();
return ksort($items);
}

SetEnv APPLICATION_ENV production

Header unset ETag
FileETag None
Header set Expires "Thu, 15 Apr 2012 20:00:00 GMT"
Header unset Last-Modified

# Netscape 4.x has some problems...

# MSIE masquerades as Netscape, but it is fine
# BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

# NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48
# the above regex won't work. You can use the following

# Don't compress images

# Make sure proxies don't deliver the wrong content

Normally you should build php for your new extension by running the following commands

phpize
./configure (add some configuration parameters here)
make

But it won’t help and gives an error like this:

mach-o, but wrong architecture in Unknown on line 0

The solution is to add some extra build parameters before the configuration command:

MACOSX_DEPLOYMENT_TARGET=10.6 CFLAGS=’-O3 -fno-common -arch i386 -arch x86_64′ LDFLAGS=’-O3 -arch i386 -arch x86_64′ CXXFLAGS=’-O3 -fno-common -arch i386 -arch x86_64′ ./configure

Then you’re ready to go.

RewriteEngine On

RewriteRule ^\.htaccess$ - [F]

RewriteCond %{REQUEST_URI} =""
RewriteRule ^.*$ /public/index.php [NC,L]

RewriteCond %{REQUEST_URI} !^/public/.*$
RewriteRule ^(.*)$ /public/$1

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^.*$ - [NC,L]

RewriteRule ^public/.*$ /public/index.php [NC,L]

kaynak: şurası.

Mac’e geçmemle beraber uzun süredir kullandığım Zend Studio 5.5 ve Aptana’dan da Zend Studio 7′ye geçmeye karar verdim. Zend Studio 7 eclipse üzerine kurulmuş harika bir ide. Gerçi ben hala alışabilmiş değilim ama artık bir değişikik yapmam şarttı.

Neyse, Zend Studio 7 malesef debugger olarak sadece Zend Debugger’a izin veriyor. Xdebug disable edilmiş durumda. Ancak ufak bir trick ile bunu değiştirmek mümkün. Şöyleki;

1. Zend Studio folder’a gidilir. cd /Applications/Zend/Zend\ Studio\ -\ 7.0.0
2. cd pluginsmkdir disabled
3. mkdir disabled
4. mv com.zend.php.debug* disabled
5. Bir de configurasyon dosyasında ufak bir değişiklik yapmamız gerek. open -a TextWrangler com.zend.php_<ZSE_version_number>/plugin_customization.ini
6. ‘org.eclipse.ui.workbench/UIActivities.com.zend.php.debug.ui.XDebugActivity’ alanının değerini ‘true’ olarak değiştir.
7. Zend Studio’yu yeniden başlat.
8. Preferences içinde PHP -> Debug sayfasında gerekli değişiklikler yapılır (debugger olarak Xdebug seç, PHP executable path i göster vb.)

Afiyet olsun.

echo floor(($now->getTimestamp() - $dob->getTimestamp()) / (24 * 60 * 60)) / 365;
