Count Special Characters in String

Question

i want to count special character in emails
[email protected] = 7
[email protected] = 6
[email protected] = 5
[email protected] = 6

Answer 1

From your given example I conclude that task is to count period (.) in substring before @.
@ is also special charecter. if you meant to count special charecters then given examples are wrong.

Answer 2

Use Preg_match_all
