PHP | gmp_xor() Function Last Updated : 14 Apr, 2018 Comments Improve Suggest changes Like Article Like Report The gmp_xor() is an in-built function in PHP which is used to calculate the XOR of 2 GMP numbers (GNU Multiple Precision : For large numbers). Syntax: gmp_xor( $num1, $num2 ) Parameters: This function accepts two GMP numbers $num1 and $num2 as mandatory parameters shown in the above syntax. These parameters can be a GMP object in PHP version 5.6 and later, or we are also allowed to pass a numeric string provided that it is possible to convert that string to a number. Return Value: This function returns a positive GMP number which is the XOR of $num1 and $num2. Examples: Input : $num1 = "3" $num2 = "5" Output : 6 Input : $num1 = 1 $num2 = 1 Output : 0 Below programs illustrate the gmp_xor() function: Program 1: The program calculates the XOR of two numbers when numeric strings as GMP numbers are passed as arguments. php <?php // PHP program to calculate the XOR // of two numbers using gmp_xor() // numeric string passed as arguments $xor = gmp_xor("3", "5"); // prints the GMP number which xor // of two numeric strings echo $xor; ?> Output: 6 Program 2: The program calculates the XOR of two numbers when GMP numbers are passed as arguments. php <?php // PHP program to calculate XOR // of two numbers // GMP numbers passed as arguments $xor1 = gmp_init("1101101110", 2); $xor2 = gmp_init("0110011001", 2); // function calculates the XOR of two numbers $xor3 = gmp_xor($xor1, $xor2); // prints the GMP number which is the // XOR of two GMP numbers // gmp_strval Convert GMP number to string // representation in given base(default 10). echo gmp_strval($xor3, 2); ?> Output: 1011110111 Reference: http://php.net/manual/en/function.gmp-xor.php Comment More infoAdvertise with us Next Article PHP | gmp_xor() Function C ChetnaAgarwal Follow Improve Article Tags : Misc Web Technologies PHP PHP-gmp Practice Tags : Misc Similar Reads PHP | gmp_pow() Function The gmp_pow() is an inbuilt function in PHP which is used to calculate the power raised to a number of a GMP number and an integer (GNU Multiple Precision: For large numbers).
