Hi,
I didn't even think PHP would do anything until I just tried it.
<?php
for ($i = "A"; $i <= "Z"; $i++){
echo $i . "<br />";
}
?>
outputs:
A
B
C
....
X
Y
Z
AA
AB
....
AY
AX
....
YA
YB
....
YY
YZ
Why it continues after Z is not clear to me, and why it doesn't continue
until ZZ isn't either.
This works better and (more importantly) as expected:
<?php
$alfabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
foreach(preg_split("!!", $alfabet, -1, PREG_SPLIT_NO_EMPTY) as $char) {
echo $char . "<br />";
}
?>
By the way, this code froze my browser:
<?php
for ($i = "A"; $i <= "z"; $i++){
echo $i . "<br />";
}
?>
