Is there a function in PHP akin to substr() for integers?

Question

I have a phone number which will be recorded as an int (e.g 1234512312345) on my database but which I would like to represent as (12345) 123 - 12345 on a webpage. If it was a string I would use substr but it seems inelegant to convert it to a strval.

While I appreciate that integers and strings are categorically distinct, is there a means to do something to this effect without writing a less-than efficient function myself?

Answer 1

You can try vprintf or vsprintf with sscanf

$data = 1234512312345;
vprintf("(%d)-%d-%d",sscanf($data, "%5d%3d%5d"));

Output

(12345)-123-12345

*Note

If you want to return it has a value then it should be

$var = vsprintf("(%d)-%d-%d",sscanf($data, "%5d%3d%5d"));
        ^
