Question

I completely have no idea how to do this as I am not a regexp expert..

But I wanted to search and count a specified CASE-INSENSITIVE text in a long string, for example:

the function:

int count_string ( string $string_to_search, string $input_search )

example usage and result:

$my_string = "Hello my name is John. I love my wife, child, and dog very much. My job is a policeman.";

print count_string("my", $my_string); // prints "3"
print count_string("is", $my_string); // prints "2"

Is there any built-in function to do this?

Any kind of help would be appreciated 🙂

Answer 1

substr_count() is what you are looking for.

substr_count(strtolower($string), strtolower($searchstring)) would make the count insensitive.
