In the given code snippet, what potential pitfalls could occur when using the if statement with the count() function in PHP?

When using the `if` statement with the `count()` function in PHP, a potential pitfall could occur if the `count()` function returns `0` for an empty array or if the variable being checked is not an array. In such cases, the `if` statement may not behave as expected. To solve this issue, it is recommended to first check if the variable is an array before using the `count()` function. 

// Check if the variable is an array before using the count() function
if(is_array($array) && count($array) > 0) {
    // Perform actions if the array is not empty
    // Example: echo the count of the array
    echo "Array count: " . count($array);
} else {
    // Handle the case when the array is empty or not an array
    echo "Array is empty or not an array";
}
