PHP implode explode first and last array value

Question

i'm still a freshman on PHP. So i have a variable called 'full name' and i was trying to explode and implode the first and the last variable value.

$fullname='Andre Filipe da Costa Ferreira';
$namepieces=explode('', $fullname);
$flname=implode('', namepieces[0], namepieces[lastvar]);
echo "Welcome".$flname;

I would appreciate if someone could help me! Thanks :D

Answer 1

This with name pieces separated with a space, and works with a single name piece like Andre:

<?php
$fullname = 'Andre Filipe da Costa Ferreira';
$namepieces = explode(' ', $fullname);
$n = count($namepieces);
if($n > 1) {
  $flname = implode(' ', array($namepieces[0], $namepieces[$n-1]));
} else {
  $flname = $namepieces[0];
}
echo "Welcome " . $flname;
//
?>

This gets:

Welcome Andre Ferreira

Answer 2

Try:

$names = explode(" ", "Andre Filipe da Costa Ferreira");
printf("Welcome %s %s", current($names), end($names));

where current() gets its first element, and end() last one.
