The PHP Function GMP_Strval

The php function gmp_strval converts a GMP number into its string representation. It takes in two arguments: num and base. This function is used when numbers are too large to fit into the limited range of operations that PHP can perform on its own, such as basic arithmetic and factorials.

The function uses the gmp library to perform its operations. GMP provides math functions that operate on integers of arbitrary length, which makes them faster for figuring out complex numbers than PHP’s own built-in functions can be.

Most GMP functions accept GMP numbers as their argument, defined as resource below, but they can also accept numeric or string values as long as they can be converted to a number. However, these functions are usually slower than those that can use integer arguments because they must interpret the string or numeric literal first before GMP comes into play.

The gmp_strval() function is a GMP function that changes a number into its string representation. It takes in a GMP number as its first parameter and an index place for the bit as its second. This function will return the resulting string.

This function is useful for converting numbers into a string that can be used in associative arrays. It can also be used to find the bitwise XOR of the numbers that you give it. The value that you want to change can be in any of the supported base values: decimal, hexadecimal, or octal.
