Question

I want to build pattern for preg_match that will match any string with length 1 – 40 chars. I found this:

^[^<\x09]{1,40}\Z

But with that one I recieve this error message:

function.preg-match]: Unknown modifier '<' in ....

Any suggestion ?

Answer 1

/^.{1,40}$/ should match any string that’s 1 to 40 characters long.

What it does is that it takes the ., which matches everything, and repeats it 1 to 40 times ({1,40}). The ^ and $ are anchors at the beginning and end of the string.
