String Length

[Anon]

whats the command for finding the length of a string?

[Anon]

Hi,
The command is: strlen

Example:
<?
$string = "Hello";
print(strlen($string));
?>

You could at least try to read the manual.

sorry guys, typed the wrong thing :[
i meant
how can you count how many words in a string

[arnihr]

split spaces up, and count the arrays from the split? 🙂

understood that brilliant idea of mine?

Hope it helps, Arni

yeah
thx
i did this:

$words = split (" ", $text);
$num_words = count($words);

That works.. up to a point..
It literally splits around spaces.
So if you have a string of four spaces, you'd get 5 results,
even though there is not one word in there.

instead, use something like this:
$aParts=preg_split("/(\w)+(\W)+/",$sString);
echo count($aParts);

That will count how many times there is a word character followed by a non-word character.
