I have a string in php like this.
$str = "ABCCCDE" //Contains repeated character CCC more than 2 times
I want to know if there is any repeated characters more than 2 times using regular expression.
Thanks in advance

if (preg_match('/(.)\\1{2}/', $str))
echo "Has 3 same characters consecutively!";
The (.) will match any character (except new lines), and the \1 will match a pattern same as the first matched group — in this case, the character we've just matched. So this RegEx will match 3 same consecutive characters.

It returns 1 when there is string "abccde". It should return 1 only there is a repeated character more than 2 times
You can use:
'/(.)\1\1/'
E.g.:
preg_match('/(.)\1\1/', $str, $matches);
