GAME FOR U : A = 0 and A != 0 ??????

Hi folks,

Here's a little game. You have to find out if there is an error and if so, where the error is, ok ? (PHP Version 4.3.0)

THE CODE :

$A=0;
echo '$A = ' .$A . ' ';
echo '$A ' . ($A ? 'exists' : 'does not exist') . ' ';
echo '$A ' . ($A = 0 ? '= 0' : '!= 0') . ' ';

THE DISPLAY :

$A = 0
$A does not exist
$A != 0

don't see any prob.

Replace the first line of code ($A = 0😉 whith :

$A = strpos('12345', '1');

;-)

in php
0 is the same as FALSE
1 is the same as TRUE

take a LOOOOOOOOOOOOOOOOOOK

$A=0; 
echo '$A = ' .$A . '<br>'; 
echo '$A ' . (isset($A)? 'exists' : 'does not exist') . '<br>'; 
echo '$A ' . (($A==0) ? '= 0' : '!= 0') . '<br>';

AND DISPLAY is Like This :
$A = 0
$A exists
$A = 0

what's about that??

echo '$A = ' . $A . ' ';
echo '$A ' . (isset($A) ? 'exists' : 'does not exist') . ' ';
echo '$A ' . ($A == 0 ? '= 0' : '!= 0') . ' ';

EDITED:
oh ... sorry ... someone was faster than me during coding!! 😉

Ok, ok, ok... you were pretty quick, guys. Or maybe this wasn't so hard ;-)

This little "study" shows that there are good coders around here.

The prize for the winners : my consideration (not sold very much on the market ;-)

Keep going on.

I'll be back soon with new exercises...
