The browser returns a bunch of email addresses (one or more) entered into a textarea block, separated by commas and/or whitespace. I try to split it and I get the first element repeated by itself up to limit-1, and the last element of the resulting array contains all the elements.
To try and figure out what's wrong, I took a basic example from the WROX PHP book:
$str = "one two three four";
$pat = " ";
$array = split($pat, $str, 4);
print "$array[0]<BR>\n";
print "$array[1]<BR>\n";
print "$array[2]<BR>\n";
print "$array[3]<BR>\n";
And this is what appears on the WEB page:
one
one
one
one two three four
According to the book, I should see:
one
two
three
four
So what's wrong?
Thanks for your patience with this newbie.
