How to use hexdec() and decbin() Functions In PHP

Using Custom Conversion Logic

This PHP code defines a function hexToBin() that converts a hexadecimal number to a binary number. It converts the hexadecimal number to a decimal number, then to a binary number, and add the binary padding representation with leading zeros to ensure each hexadecimal character corresponds to 4 bits. The function is demonstrated by converting the hexadecimal value “DA” to its padded binary equivalent, which is echoed as 00011010.

Example: This example shows the implementation of the above-mentioned approach.

PHP

<?php

function hexToBin($hex) {
    $decimal = hexdec($hex);
    $binary = decbin($decimal);
    
    $paddedBinary = str_pad(
        $binary, 
        strlen($hex) * 4, 
        '0', 
        STR_PAD_LEFT
    );
    
    return $paddedBinary;
}

// Driver Code
$hexVal = "DA";
$binVal = hexToBin($hexVal);

// Output: 00011010
echo $binVal;

?>

Output

11011010

Hexadecimal to Binary Converter in PHP

Hexadecimal and binary are two number systems commonly used in computing. Hexadecimal (base 16) is often used to represent binary values in a more human-readable format. Hexadecimal to Binary converter is a common task in programming, especially when dealing with low-level operations or data manipulation.

Examples:

Input: hexValue = "1A"
Output: 00011010

Input: hexValue = "DA"
Output: 11011010
