How can I get the last 2 digits of:
<departureDate>200912</departureDate>
to my object:
$year = $flightDates->departureDate->year;
443
Last two digits of a number is basically the tens place and units place digit of that number. So given a number say 1439, the last two digits of this number are 3 and 9, which is pretty straight forward.
To get the last 2 digits of a number:Call the slice() method on the string, passing it -2 as a parameter. The slice method will return the last 2 characters in the string. Convert the string back to a number to get the 2 last digits.
// first two
$year = substr($flightDates->departureDate->year, 0, 2);
// last two
$year = substr($flightDates->departureDate->year, -2);
But given the fact that you're parsing a date here it would be smarter to use the date function.
p.e. strtotime() and date() or even:
<?php
$someDate ='200912';
$dateObj = DateTime::createFromFormat('dmy', $someDate);
echo $dateObj->format('Y');
// prints "2012" .. (see date formats)
You can just address it as string, the function substr will convert it automatically:
<?php
//$year = '200912';
$year = $flightDates->departureDate->year;
echo substr( $year, -2 );
?>
Take a closer look at substr function. If you want the result to be a strict integer, then just add (int) in front of the return.
But, as Jan. said, you should better work with it as a date:
<?php
//$year = '200912';
$year = $flightDates->departureDate->year;
$date = DateTime::createFromFormat( 'dmy', $year );
echo date( "y", $date->getTimestamp() );
?>
