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);
});

Look for the hard drives device with mount or sudo fdisk -l and unmount it. In my case it’s going to be sda.
Backup uncompressed image:
sudo dd if=/dev/sda of=/home/sda.bin bs=1024
Backup compressed image:
sudo dd if=/dev/sda bs=1024 | gzip > /home/user/sda.bin.gz
If the target file system where the image is going to be created can’t have files larger than 4GB for example (as for FAT32) you’ll have to split the output:
sudo dd if=/dev/sda conv=sync,noerror bs=64K | gzip -c | split -b 2000m - /media/usbdrive/sda.bin.gz
Restore uncompressed image:
sudo dd if=/home/user/sda.bin of=/dev/sda bs=1024
Restore compressed image:
sudo gzip -dc /home/user/sda.bin.gz | dd of=/dev/sda bs=1024
Restore compressed and splited image:
sudo cat /media/usbdrive/sda.bin.gz.* | gzip -dc | dd of=/dev/sda conv=sync,noerror bs=64K
You can do the same with only one partition of the hard drive if you replace sda with sdaX being X the partition number.

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: .+
