How to use Conversion Algorithm In PHP
In this case, we use mathematical conversion algorithm to convert binary to its decimal equivalent. Here, we convert a binary number to decimal by iterating through each bit and summing up the corresponding powers of 2.
PHP
<?php function binToDec($binNum) { $decNum = 0; $len = strlen($binNum); for ($i = 0; $i < $len; $i++) { $decNum += (int)$binNum[$i] * pow(2, $len - $i - 1); } return $decNum; } $binNum = '110010'; $decNum = binToDec($binNum); echo "Decimal Number: " . $decNum; ?> |
Output
Decimal Number: 50
