What potential issues can arise from using a large number of if-else statements in PHP code?

Using a large number of if-else statements in PHP code can lead to code that is difficult to read, maintain, and debug. It can also make the code more prone to errors and make it harder to add new conditions in the future. One way to address this issue is by using a switch statement instead of multiple if-else statements. 

// Example of using a switch statement instead of multiple if-else statements
$day = "Monday";

switch ($day) {
    case "Monday":
        echo "Today is Monday";
        break;
    case "Tuesday":
        echo "Today is Tuesday";
        break;
    case "Wednesday":
        echo "Today is Wednesday";
        break;
    // Add more cases as needed
    default:
        echo "Unknown day";
}
