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

You're missing the $ in front of namepieces on line 3; otherwise - what is the issue that you're having? Do you get an error message? A blank screen? The wrong data? –  andrewsi Nov 29 '13 at 18:14
    
yes, please clarify with an example: what would input look like, what should output be –  hanzo2001 Nov 29 '13 at 18:19

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

You need to use end($namepieces); which returns the value of the last element or FALSE for empty array.Also your are missing $ before namepieces

$flname=implode('', $namepieces[0], end($namepieces));

end()

Another example taken from php.net for getting first and last element from array

$items = array( 'one', 'two', 'three' );
$lastItem = end( $items ); // three
$current = current( $items ); // one

using current probably is tricky when used around iterators. –  Thom Wiggers Nov 29 '13 at 18:22

@ThomWiggers for OP's problem it suits best i have shown him both ways either using index 0 or current() –  M Khalid Junaid Nov 29 '13 at 18:24
    
current() isn't a way to get index 0: current() is a way to get the current element of an array when walking through it using an iterator/next()/prev(). That it happens to be index 0 at first isn't a reason to use current() for this. –  Thom Wiggers Nov 29 '13 at 18:30

@ThomWiggers because its php's built-in function –  M Khalid Junaid Nov 29 '13 at 18:41

Its beter way I guess

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