What are some strategies for troubleshooting PHP code and resolving issues with conditional statements like the one used in the forum thread?

Issue: The conditional statement in the forum thread is not working as expected, potentially due to syntax errors or incorrect logic. To troubleshoot this issue, carefully review the conditional statement for any syntax errors, ensure that the logic is correct, and consider using debugging tools like var_dump() to inspect variables and values.

// Example of troubleshooting and fixing a conditional statement
if ($user_age >= 18 && $user_country == 'USA') {
    echo "You are eligible to access the content.";
} else {
    echo "Sorry, you are not eligible to access the content.";
}
