How can PHP developers effectively troubleshoot and debug conditional statements like isset() to ensure proper functionality in scripts?

When troubleshooting and debugging conditional statements like isset() in PHP scripts, developers can effectively ensure proper functionality by checking the variable existence and value before using it in conditional statements. This can prevent errors and unexpected behavior in the script. 

// Example of checking variable existence and value before using it in a conditional statement
if(isset($variable) && $variable == 'value'){
    // Perform actions based on the condition
} else {
    // Handle the case where the condition is not met
}
