How can error messages like "Trying to get property of non-object" in PHP be effectively troubleshooted and resolved?

When encountering an error message like "Trying to get property of non-object" in PHP, it typically means that you are trying to access a property of a variable that is not an object. To troubleshoot and resolve this issue, you should first check if the variable is indeed an object before trying to access its properties. This can be done by using the `is_object()` function to validate the variable type.

// Check if the variable is an object before accessing its properties
if (is_object($variable)) {
    // Access the object properties here
    $propertyValue = $variable->propertyName;
} else {
    // Handle the case where the variable is not an object
    echo "Variable is not an object";
}
