anonymoux: Please guys, I am working on my site.
But have this little problem with my php script.
I need to check if string have less than 4 characters.

$str = "33322222EEEEE";
if(!preg_match(??, $str)) {
msg = str." has less than 4 numbers/characters"
}

<?php
$str = "33322222EEEEE";
if (strlen($str)<3) {

	echo $str." has less than 3 characters";
}
else
{
	echo $str. " has more than 3 characters";
}
?>

Thank you guyz so much, but you dont seems to get my problem.

I cant use strlen because it count the overall number or characters.
I need a code than can be like:

if I enter:
11111 = it will say: only one character was entered(because I enter 1 five times. so it will disregard all the other extra times 1 was entered)

and if I enter

111122223333 = it will say: it will tell me only 3 characters are entered. (Because I enter 1, 2 and 3 repeated it, it wont cant repetitions).

Thank you!

<?php
$str = "111122223333";

echo "\"$str\" Contains ".strlen(count_chars($str,3))." distinct character(s)";
?>

NOTE:count_chars accept 2 parameters, the second parameter is known as "mode". In this case, I used "mode 3" which will return a string with all the different characters used. I then counted the characters using the more familiar "strlen" Capisce?

anonymoux: <?php
$a = 'apple';
$b = 'ball';

$duplicates = array_count_values(array_merge(str_split($a), str_split($b)));

// Array ( [a] => 2 [p] => 2 [l] => 3 [e] => 1 [b] => 1 )
print_r($duplicates);

$totalMatches = 0;

foreach($duplicates as $count) {
if($count > 1)
$totalMatches += $count;
}

// 7 matches!
echo $totalMatches . ' matches!';
?>


I have gotten what I needed.
Easy and Perfect!!!

<?php
$a = 'appleball';

$duplicates = array_count_values(array_merge(str_split($a)));

// Array ( [a] => 2 [p] => 2 [l] => 3 [e] => 1 => 1 )
print_r($duplicates);

$totalMatches = 0;

foreach($duplicates as $count) {
if($count > 1)
$totalMatches += $count;
}
// 7 matches!
echo $totalMatches . ' matches!';
?>

anonymoux: Above is a more understandable version of what I actually wanted.
in this above example. $totalMaches will come out as:
Array ( [a] => 2 [p] => 2 [l] => 3 [e] => 1 [b] => 1 )

which means letter a appears twice
letter p appears twice
letter l appears thrice
and so on....

counting duplicates and even non duplicates...

Okay..But,

<?php
$str = "111122223333666 ";

foreach (count_chars($str, 1) as $i => $count) {
   echo "There are $count occurence(s) of \"".chr($i)."\"in the string<br/>";
}
?>
