Return the last 2 digits a number

Question

How can I get the last 2 digits of:

200912

to my object:

$year = $flightDates-&         


        

Answer 1

// 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)

Answer 2

For numbers, you could use php's modulo function (http://php.net/manual/en/internals2.opcodes.mod.php):

<?php
//$year = '200912';
$year = $flightDates->departureDate->year;

echo $year % 100;
?>

Answer 3

Example 1 : You can just strip the tags with strip_tags and use substr

$number = '<departureDate>200912</departureDate>' ;
$year = substr(strip_tags($number), 0,2);
var_dump($year);

Example 2 : You can also use simplexml_load_string with substr

$number = '<departureDate>200912</departureDate>' ;
$year = substr(simplexml_load_string($number),0,2);
var_dump($year);

Output

string '20' (length=2)

Answer 4

You could use a basic aritimethic operation, like this...

while ( $var > 100 ) 
{
    $var = (int) $var / 10;
}

There could be a better solution but this one will fit fine

Answer 5

convert it to string. then take the first two element.

In java you can do this by following code. Let the variable is an integer named x . then you can use

byte[] array= Integer.toString(x).get.bytes(). 

Now array[0] and array[1] is the first two digits. array[array.length-1] and array[array.length] are the last two.

Answer 6

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() );

?>
