Hi Juliette,
As Rik already posted, you certainly can do it with regexes and as I
posted, they're much faster than the function call.
There's a syntax error in your script:
> for( $i=0; $i<$arraycount; $i++; ) {
should be:
> for( $i=0; $i<$arraycount; $i++ ) {
And a bug that actually gives the incorrect output. The first part of the
string from your function is:
Carson; David, Milne; Rebecca,
And it should be:
Carson, David; Milne, Rebecca;
For reference, against the larger data set from my timing post, your
function completes in 0.5357 seconds (compared to 0.8106 for Rik's
function version and 0.1960 for Rik's regex).
Cheers,
Andy
