Perl (5.10.1)

print "Kentucky Fried Chicken" =~ m/\b(\w)/g;

PHP (5.3)

<?php print join(array_map(function ($w){return $w[0];}, explode(' ', 'Kentucky Fried Chicken')));

— @jroussel

→ Version un peu plus con⋅cise : 😁

<?php array_map(function($w) { print $w[0]; }, explode(' ', 'Kentucky Fried Chicken'));

— @wo0dyn

<?php echo str_replace(' ', '', join(array_intersect(str_split($s = "Kentucky Fried Chicken"), str_split(strtoupper($s)))));

— @xi-ao

<?php echo preg_replace('/[a-z]| /', '', "Kentucky Fried Chicken") ?>

— @jeremyFreeAgent

<?php echo preg_replace('([^A-Z])', '', 'Kentucky Fried Chicken');

— @SaniOKh

<?php foreach(explode(' ', "Kentucky Fried Chicken") as $w) echo $w[0];

— @jeremyFreeAgent

Python (2.7.1+)

print ''.join(w[0] for w in 'Kentucky Fried Chicken'.split())
# or
import re; print re.sub('[^A-Z]', '', 'Kentucky Fried Chicken')
# or short-crappiest version ever (sorry!)
print 'KFC'#Kentucky Fried Chicken
# → yeah, we need more rules on that exercise…

— @wo0dyn

print ''.join(c for c in "Kentucky Fried Chicken" if c.isupper())
# or
import re; print ''.join(re.findall(r'\b\w', 'Kentucky Fried Chicken'))
# or
import re; print ''.join(re.findall(r'[A-Z]', 'Kentucky Fried Chicken'))

Ruby

print "Kentucky Fried Chicken".gsub /[^A-Z]/, ''
# or
"Kentucky Fried Chicken".each_char{|c| print(('Z' >= c && 'A' <= c)?c:'')}

— Cyril

<?php echo preg_replace('/[a-z]| /', '', "Kentucky Fried Chicken") ?>

# !/bin/bash

for w in $(echo "Kentucky Fried Chicken" | tr " " "\n"); do echo -n ${w:0:1}; done;

@jeremyFreeAgent Bon, j'ai ajouté mais l'idée à la base, c'était de récupérer les premières lettres de chaque mot hein ! Coquin.
Du coup, j'ai fait une autre version python pour la peine :

import re; print re.sub('[^A-Z]', '', 'Kentucky Fried Chicken')

@xi-ao Joli ! Ajouté.

@duboisnicolas Du coup c'est pareil pour Perl ! ;)

<?php foreach(explode(' ', "Kentucky Fried Chicken") as $w) { echo $w[0]; }; ?>

<?php preg_replace_callback('~\b(\w)~', function($w) { print $w[0]; }, 'Kentucky Fried Chicken');

@jeremyFreeAgent ajouté sans les accolades pour gagner quelques caractères. 😏

Bien joué @duboisnicolas ! Je n'y avais pas pensé :s

Sans utiliser les majuscules (mais en utilisant des regexp) par Cyril R. :

"Kentucky Fried Chicken".replace(/([a-z])[a-z]* ?/gi, '$1')

@xi-ao: quel langage ?

<?php
echo "KFC";
?>

ben quoi

Ça marche pas @n1k0 : "using the string “Kentucky Fried Chicken” once."

Une solution un peu plus complète:

<?php
"Kentucky Fried Chicken";
echo "KFC";
?>

:D

:') @naholyr 👍

Encore plus fort

<?php /* kfc.php */ ?>
<style>span {display:none}</style>
<p>K<span>entucky </span>F<span>ried </span>C<span>hicken</span></p>

CA J'AIME @n1k0

Par contre, visibility: hidden, va laisser l'espacement alors que display: none, non.
