PHP - detect whitespace between strings

Question

How would I go about detecting whitespace within a string? For example, I have a name string like:

\"Jane Doe\"

Keep in mind that I don\'t want to trim or re

Answer 1

You may use something like this:

if (strpos($r, ' ') > 0) {
    echo 'A white space exists between the string';
}
else
{
    echo 'There is no white space in the string';
}

This will detect a space, but not any other kind of whitespace.
