Question

So i’m trying to preg_match an address in PHP.

It should be letters SPACE numbers and not numbers SPACE letters.
So, like this: Myplace 16.
The length of the numbers and letters doesn’t matter, but they can’t be mixed together.

I already tried this one but this one doens’t check spaces:

if(preg_match("/^[0-9a-zA-Z_]{5,}$/", $adres) === 0)
{
echo 'Address is wrong';
}

Thanks in advance!

Answer 1

The pattern you showed doesn’t correspond at all to what you’re trying to do. For your purpose, you would do something like

/^[a-zA-Z]+\ +[0-9]+$/

This checks for at least one letter at the beginning of the string followed by 1 or more spaces followed by 1 or more digits, at which point the string must end.

Unless, of course, I misunderstand what you are trying to achieve…
