Count Characters?

[brianb]

Hello,

Looking for a solution to count the characters in a string...

Any/all help is appreciated! Thanks in advance!

[onion2k]

$string = "This is in completely the wrong folder";

for ($x=0;$x<strlen($string);$x++) {

 $unique[$string[$x]]++;

}

echo count ($unique);

:p

Added bonus, if you print_r($unique) it'll tell you how many of each character there are.

Correction:

@$unique[$string[$x]]++;

to prevent warnings

... or ...
[man]count_chars()[/man]

$result=count_chars($string,1);
echo count($result);

WTF? You write all your code with warnings turned off? Are you mad? Surely that would make debugging a total nightmare?

That, in my opinion, is awful advice.

Check!

i didn's say a thing then :rolleyes:

hmm... why wouldnt strlen() suffice in this case?

At most there's still count_chars(), but the OP didnt seem to want more than just the number of characters.
