PHP - How can I check if a string contains only lower case characters? -

how can check if string in php contains lower case characters?

i tried:

        if (!preg_match('~[a-z]~', $_post['name']))          {           $errors[] = 'caracteres inapropriados!';          }

thanks!

this should work you:

it return's true if characters lower case!

if(ctype_lower($_post['name'])) echo "all characters lower case!";

php
