A GMP object, an int, or a string that can be interpreted as a number following the same logic as if the string was used in gmp_init () with automatic base detection (i.e. when base is equal to 0).
Jul 11, 2025 · The gmp_popcount () is a built-in function in PHP which is used to find the population count of a GMP number (GNU Multiple Precision : For large numbers). We can also say that this function is used to find the number of set bits in the binary representation of a GMP number.
The gmp_popcount () function calculates the population count. The gmp_popcount () counts the number of non-zero entries ('1' bits) in given byte, string etc. PHP gmp_popcount () function returns population count as an integer.
It can be either a GMP number resource, or a numeric string given that it is possible to convert the latter to a number.
