Use bin2hex() Function in PHP 7.4 With Example

The `bin2hex()` function in PHP 7.4 converts binary data into a hexadecimal representation. This can be useful when you need to represent binary data in a human-readable form, such as when encoding binary data for storage or transmission. Here's an example of using `bin2hex()` in PHP 7.4:

<?php
// Binary data (string)
$binaryData = "Hello, World!";
// Convert binary data to hexadecimal
$hexData = bin2hex($binaryData);
// Output the hexadecimal representation
echo "Hexadecimal Representation: " . $hexData;
?>

Output:

Hexadecimal Representation: 48656c6c6f2c20576f726c6421
