explode or split with mutiple possible delimiters 1

[southbeach]

I found sample #2 here

http://us.php.net/manual/en/function.split.php

which claims to do exactly what I need but it is giving me a warning or error.

Warning: split() [function.split]: REG_ERANGE in /usr/haf/web/default.php on line 13

Warning: split() [function.split]: REG_ERANGE in /usr/haf/web/default.php on line 14

The syntax is as follows

list($mA,$dA,$yA)=split('[/-.]', $valA);
list($mB,$dB,$yB)=split('[/-.]', $valB);
if ($valA != '') $valA = $yA.'/'.$mA.'/'.$dA;
if ($valB != '') $valB = $yB.'/'.$mB.'/'.$dB;

If I add @ to prefix the split() function, no warning comes up on screen but the call fails, variables are empty.

All that said, am I doing something wrong or is the sample listed on php.net misleading ???

Thank you all in advance for your assistance!

are you sure that the regex should not be

'[/.-]'

you seem to be reversed a bit. thus will be mis-using the dot character.

I really did not know it had to be in an exact order ... I thought about it as I looked at the example I cited and the code I typed, but then said to myself that that would not make any sense ...

From writing Unix scripts, I remember using [a-z,0-9] and the like to encompass a range of characters, it never occurred to me that in this case the order in which I specify them would make a difference.

I tried the code using the order as you pointed out and it works pretty well!

Oh well, live a little, learn a little ...

Thanks!

you're right. there is no need to have any particular order inside a character class. inside a character class the dot means just a dot. i did not properly read your post, i'm afraid!

the reason why your code did not work is because you put the dash between two characters. pcre then considered that you were asking for pattern matching between two characters (ie. from slash TO dot). which it couldn't deal with... by putting the dash at the end, pcre knows that you mean a dash.

And there is light at the end of the tunnel ... I love clarity, it makes me feel at ease with myself

Your explanation lifted a cloud off me - Thank you so very much for your assistance!
