function cmp($a, $b)
{
return strcmp($a->name, $b->name);
}
usort($your_data, "cmp");
Or the shorter version using closures:
usort($your_data, function($a, $b)
{
return strcmp($a->name, $b->name);
});

I have one route in my app that must have a text and a dot followed by a format. For example:
http://domain.com/image/mi-text-with-dots-.-in-.-the-.-middle.png
As you can see it’s an url that can contain dots before the dot that splits the {text} and the {_format} parts.
To make this work you have to define the route in routing.yml using a regexp for {text} this way:
dotted_url:
pattern: /image/{text}.{_format}
defaults: { _controller: AcmeDemoBundle:Demo:image, _format: png }
requirements:
_format: png|jpg
text: .+

I got this error today when running composer update for one of my Symfony2 projects:
Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 3781182 bytes) in phar:///usr/local/bin/composer/src/Composer/Util/RemoteFilesystem.php on line 202
Composers troubleshooting tells that you can increase the memory PHP can allocate editing memory_limit parameter in php.ini. I changed it from 128M to 512M but still didn’t work.
Finally the solution was to run composer update with no memory limit this way:
php -d memory_limit=-1 /usr/local/bin/composer update
If you get this warning when you connect to mongo shell in Mac OX X:
** WARNING: soft rlimits too low. Number of files is 256, should be at least 1000
You can increase that limit by just running this on the Mac OS X shell:
launchctl limit maxfiles 1024 1024
This other command has the same effect but it will only last until the next system reboot:
ulimit -n 1024
Restart mongod and it shouldn’t complain any more.
While updating all the ports of macports I got this error:
---> Configuring mongodb Error: mongodb cannot be built while v8 is active. Error: Please deactivate v8 and try again. Error: You can reactivate v8 again later. Error: org.macports.configure for port mongodb returned: v8 is active
To deactivate v8 run:
sudo port -f deactivate v8
Run the update process again:
sudo port upgrade outdated
And finally activate v8 again:
sudo port activate v8
