<?php
use Mobile_Detect;
$mb = new Mobile_Detect;
if($mb->isIpad()){

CakePHP3: Fetch a particular column from all rows
| id | country | capitol |
| 1 | USA | Washington DC |
| 2 | Japan | Tokyo |
| 3 | United Kingdom | London |
And you want to fetch data like this:
['Washington DC', 'Tokyo', 'London']
Then do this:
$capitols = $this->countries
->find()
->extract('capitol')
->toArray();

CakePHP3: Check if record exists
To check by primary key:
if ($this->Users->exists($id)) {
}
To find by specifying where clause:
if ($this->Users->exists(['email' => $email])) {
}
Much more convenient than using find('count').

Bash: working with filenames containing spaces
for i in `find . -type f`
do
cp "${i}" "${i}.bak"
done
This fails when filenames contain spaces, as bash uses whitespace, tab and LF as the default delimiter. Solution? Do this:
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")
