PHP Typecasting Error Changing Value

Question

I am trying to store a phone number and I have reached some problems due to type casting? Anyone have any suggestions as to what is happening here?

var_dump((int)"6467838439"); // displays 'int 2147483647'

you reached the maximum range of integer in 32-bit system it is 1 to 2147483647 and you have 6467838439. So when you try to convert it in integer type it is converted to the maximum range of int which is 2147483647. You can only store it as string — Shakti Singh

Phone numbers should be stored as text. They generally can't be stored as integers due to integer overflow.

An integer is 32 bits and has a finite size of approximatly 2 billion so your phone number is being truncated. You should store it as a string.
