how to deal with int overflow in php

Question

I am trying to execute below expression in php

pow(26, 36357)

It is showing incorrect output due to very long integer value.
How to deal with it and get the correct output?

Answer 1

you can use gmp_pow() functions if you have gmp extension enabled or bcpow() if you have bc_math extension enabled.

$a = gmp_pow(26, 36357);

or,

$a = bcpow(26, 36357);

gmp_pow(), bcpow()
