How can i determine the number of characters in a string? I am using substr
to cut off the last 4 characters of a string. Which is working great. But I
want to replace the 3 charcters with "..." only if there are over 20
charcters . I tried substr_replace but it appears on everything no matter
how many characters. I am trying to do this is simple terms:
if the string was:
hi my name is
it is returned shortened to:
hi ...
Any help appreciated.
