XOR of Two Binary Strings using Bitwise Operators on Characters
We can also perform the XOR operation on each character of the binary strings individually.
<?php
function xorOperation($bin1, $bin2) {
$result = '';
$length = max(strlen($bin1), strlen($bin2));
$bin1 = str_pad($bin1, $length, '0', STR_PAD_LEFT);
$bin2 = str_pad($bin2, $length, '0', STR_PAD_LEFT);
for ($i = 0; $i < $length; $i++) {
$bit1 = (int)$bin1[$i];
$bit2 = (int)$bin2[$i];
$xorBit = $bit1 ^ $bit2;
$result .= (string)$xorBit;
}
return $result;
}
// Driver code
$bin1 = "1101";
$bin2 = "1011";
echo "XOR Operation on Binary: "
. xorOperation($bin1, $bin2);
?>
Output
XOR Operation on Binary: 0110
Explanation:
- xorOperation Function: This function performs the XOR operation on each character of the binary strings.
- $bit1 and $bit2: Variables that store the individual bits from the binary strings.
- $xorBit: Stores the result of the XOR operation on the individual bits.
PHP Program for XOR of Two Binary Strings
Given two binary strings, the task is to calculate the XOR of two binary strings in PHP. The XOR operation is a bitwise operation used in computer science and digital electronics. It takes two binary strings as input and produces a binary string as output, where each bit in the output is the result of the XOR operation on the corresponding bits in the input strings.
