Hi,
I have a string in my program which can contain all parts of an address. If
any part of the address is missing, it still puts in the trailing comma - so
an address can look like
The Big House, Long Lane,,,London,,E1C 1VA
I want to run a regular expression on this to strip out the duplicate
commas. Visiting http://www.design215.com/toolbox/regexp.php, I worked out
that the expression I want is
/(,){2,}/g,", "
('worked it out' = it works on the tester on that site!)
I want to use this expression in code, and have tried
$longstring = "The Big House, Long Lane,,,London,,E1C 1VA"
$pattern = '/(,){2,}/g,", "';
ereg($pattern, $longstring, $shortstring);
echo "[".$shortstring[0]."]";
But nothing is displayed.
Can anyone point out where I'm going wrong?
Hmmz, I'd use PCRE:
$shortstring = preg_replace('/,+/',', ',$longstring);
