How can a byte array be converted to hexadecimal in PHP?

To convert a byte array to hexadecimal in PHP, you can use the `bin2hex()` function. This function takes a string of bytes as input and returns the hexadecimal representation of those bytes. You can simply pass your byte array to this function to get the hexadecimal representation. 

// Byte array
$byteArray = [0x48, 0x65, 0x6c, 0x6c, 0x6f];

// Convert byte array to hexadecimal
$hexString = bin2hex(implode(array_map("chr", $byteArray)));

echo $hexString; // Output: 48656c6c6f
