[RESOLVED] Check if uppercase

obrienkev

Hi all,

How do I check if a string is all uppercase?

And if it is I want to make it bold (apply a css style to it)

I was using something like this...

if (strtoupper($date))
{
td {
     font-weight: bold;
}
}

there are functions in the manual below the explanation of strtoupper: www.php.net/strtoupper

if you convert a string to upper case and it doesn't change compared to the way it looked like before... it's already uppercase

if (strtoupper($the_string) == $the_string) {
  echo '$the_string contains only upper case letters
         and maybe other non-letter characters';
}

And your styling will not work like that: you are trying to use CSS style notation in HTML tag properties and the syntax is different. Do it properly with a CSS class

echo '<td';
if (strtoupper($date)) {
   echo ' class="boldTxt"'; 
} 
echo '>';

From PHP 4.0.4., there is [man]ctype_upper/man which may be what you are looking for with respect to the way non-letter characters are treated.

Yup. ctype_upper is the one!. Cheers guys.

Bravo old chap. Much neater than the way I was thinking

It took you three years to think it though? 🙂
