Expressions are the most important building blocks of PHP. In PHP, almost anything you write is an expression. The simplest yet most accurate way to define an expression is "anything that has a value".
** is an arithmetic operator. It is used for Exponentiation.It gives Result of raising one variable to the other varibale's power So if we want nth power of any number for that this operator is used.
For example result of $x ** $y is raising $x to the $y'th power and this operator is introduced in PHP 5.6.
Now 5**2 = (base = 5 & exponent = 2).
5**2 = 25.Modal content
