In the PHP code snippet provided, what is the difference between the assignment operator "=" and the comparison operator "=="?

In PHP, the assignment operator "=" is used to assign a value to a variable, while the comparison operator "==" is used to compare two values for equality. It is important to use the correct operator in the appropriate context to avoid unintended consequences or errors in your code. If you mistakenly use the assignment operator when you intended to use the comparison operator, it can lead to unexpected behavior in your code. 

// Incorrect usage of assignment operator instead of comparison operator
$number = 5;

// Correct usage of comparison operator
if ($number == 5) {
    echo "The number is 5.";
}
