Built-in PHP algorithms

Now, we will check some of the built-in functionalities of PHP that solves lots of our algorithmic implementation required for day-to-day operations. We can categorize these functions into mathematics, string, cryptography and hashing, sorting, searching, and so on. We will explore the base conversion algorithms now:

• base_convert: This function is used for base conversion of a number. The base range is restricted from 2 to 36. Since the base number can be in any base and contains characters, the first parameter for the function is string. Here is an example of the function:

$baseNumber = "123456754"; 
$newNumber = base_convert($baseNumber, 8, 16); 
echo $newNumber; 

  This will produce the following output:

    14e5dec

• bin2hex: This converts a binary string to a hexadecimal string. It takes only the binary string as the parameter.
• bindec...
