split with regex

P: n/a
Hello All,

Been beating my head on the wall trying to get this working. Especially
because of my *tweener level of php and regex experience.

I have this $filename = C17AA001.000

I want to split it like this $a = C17AA $b = 001 $c = .000

I have tried this but can't get it to work.

list($a, $b, $c,) = split("^[0-9a-zA-Z]{5}[0-9]{3}\.[0-9]{3}",$filename);

echo $a;
echo $b;
echo $c;

What am I missing here? Two days of googling and php.net have not
cleared me up.

The reg ex argument you give to split is not the entire string pattern,
just the delimiter. You tell what pattern splits the string into pieces.
Now you're giving it the entire string pattern that does match the
whole string but so it basicly splits the string into two, the empty
before the string and the empty after the string.

You should be using preg_match 'stead of split. Try something like this:

preg_match("^[0-9a-zA-Z]{5}[0-9]{3}\.[0-9]{3}",$matches,$filename);
list($a, $b, $c,) = $matches;

You're using split wrong - it's for "splitting it on boundaries formed
by the case-sensitive regular expression" - the regex is the dividing
boundary, not the text you're matching.

Try this:

$filename = 'C17AA001.000';
preg_match("/([0-9a-zA-Z]{5})([0-9]{3})(\.[0-9]{3})/",$filename,
$matches);
//print_r($matches);
list($x, $a, $b, $c,) = $matches;//discard x
echo $a;
echo $b;
echo $c;

Sweet and thanks. That did it for me. And being able to get that part
working allowed me to finish and successfully test my php script which
basically renames a directory of files from

this

C17AC000.000
C17AC001.000
C17AC002.000
C17AC003.000
C17AC004.000
C17AC005.000
C17AC006.000

to this

C17AC.000
C17AC.001
C17AC.002
C17AC.003
C17AC.004
C17AC.005
C17AC.006
