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
$xor = gmp_xor( "3" , "5" );
echo $xor ;
?>
|
Output:
6
Program 2: The program calculates the XOR of two numbers when GMP numbers are passed as arguments.
<?php
$xor1 = gmp_init( "1101101110" , 2);
$xor2 = gmp_init( "0110011001" , 2);
$xor3 = gmp_xor( $xor1 , $xor2 );
echo gmp_strval( $xor3 , 2);
?>
|
Output:
1011110111
