How can you check if a variable is an array in PHP?

To check if a variable is an array in PHP, you can use the `is_array()` function. This function returns true if the variable is an array, and false otherwise. By using this function, you can easily determine if a variable is an array and take appropriate actions based on the result. 

$variable = [1, 2, 3];

if (is_array($variable)) {
    echo "The variable is an array.";
} else {
    echo "The variable is not an array.";
}
