How can the error message "Notice: Trying to get property of non-object" be resolved in PHP?

The error message "Notice: Trying to get property of non-object" occurs when trying to access a property of a variable that is not an object. To resolve this issue, you should first check if the variable is an object before trying to access its properties. This can be done using the `is_object()` function in PHP.

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