PHP Date Exercises : Print the current date in the specified format
PHP date: Exercise-3 with Solution
Write a PHP script to print the current date in the following format. To get current date's information you can use the date() function.
Sample format : (assume current date is September 01, 2013)
2013/09/01
13.09.01
01-09-13
Sample Solution:
PHP Code:
<?php
echo date("Y/m/d") . "\n";
echo date("y.m.d") . "\n";
echo date("d-m-y")."\n";
?>
Sample Output:
2017/02/16 17.02.16 16-02-17

How to Sort Multi-dimensional Array by Value?
Try a usort, If you are still on PHP 5.2 or earlier, you'll have to define a sorting function first:
Example:
function sortByOrder($a, $b) { return $a['order'] - $b['order']; } usort($myArray, 'sortByOrder');
Starting in PHP 5.3, you can use an anonymous function:
usort($myArray, function($a, $b) { return $a['order'] - $b['order']; });
And finally with PHP 7 you can use the spaceship operator:
usort($myArray, function($a, $b) { return $a['order'] <=> $b['order']; });
To extend this to multi-dimensional sorting, reference the second/third sorting elements if the first is zero - best explained below. You can also use this for sorting on sub-elements.
usort($myArray, function($a, $b) { $retval = $a['order'] <=> $b['order']; if ($retval == 0) { $retval = $a['suborder'] <=> $b['suborder']; if ($retval == 0) { $retval = $a['details']['subsuborder'] <=> $b['details']['subsuborder']; } } return $retval; });
If you need to retain key associations, use uasort() - see comparison of array sorting functions in the manual
