How can the scope of PHP variables impact the functionality of loops and conditional statements, and what strategies can be used to address this in code?

The scope of PHP variables can impact the functionality of loops and conditional statements when a variable is not accessible within a certain scope where it is needed. To address this, you can use global variables or pass variables as parameters to functions to ensure they are available where needed. 

// Example of using global variables to ensure accessibility within a loop
$globalVar = 10;

function loopExample() {
    global $globalVar;
    
    for ($i = 0; $i < $globalVar; $i++) {
        echo $i . "<br>";
    }
}

loopExample();
