What is the difference between ** and ^ in php?

@raphael_tillman 

In PHP, the double asterisk (**) is used as the exponentiation operator, whereas the caret (^) symbol is not a built-in operator.

The double asterisk (**) can be used to raise a number to the power of another number. For example:

1

$result = 2 ** 3; // 2 raised to the power of 3, resulting in 8

On the other hand, the caret (^) symbol is not recognized as an exponentiation operator in PHP. Rather, it is commonly used for other purposes, such as bitwise XOR operation.
