RE: [PHP] weird behaviour with (Z = Z)
Perhaps not a great answer, but this issue has been brought up before, and it has to do with the incrementing of a string...search the archives...i think someone had a simple workaround using chr() to get what you want... jack -Original Message- From: Christian Dechery [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 10, 2001 11:45 AM To: [EMAIL PROTECTED] Subject: [PHP] weird behaviour with (Z = Z) Z = Z is true right?? then why this weird thing happens when I have this code: for($letter=A; $letter=Z ; $letter+) echo $letter; it should output A B C D E .

RE: [PHP] weird behaviour with (Z = Z)
I would rather go for the following solution:
for($i=ord('A'); $i=ord('Z'); $i++)
echo chr($i).' ';
I know it's same and even slower as it takes two more functions to execute,
but at least it is visually closer to what Christian was trying to do.

RE: [PHP] weird behaviour with (Z = Z)
I forget which version of PHP allows you to do the following, it may be
4.0.6 or maybe 4.0.7 :
for ($a='a'; $a='z'; $a++) {
print $a;
}
The way I get around this is by :
$letter = 'a';
for ($a=1; $a=26; $a++) {
print $letter++;
}
It works or at least may easily work for your given situation. And on a
related note, in 4.0.7 the range() function will allow for :
$letters = range('a','z');
As currently it just allows for integers.
Regards,
Philip
