What is the significance of the error message "Trying to get property of non-object" in PHP?

The error message "Trying to get property of non-object" in PHP occurs when you are trying to access a property of a variable that is not an object. This often happens when trying to access an object property on a variable that is not initialized or did not return an object as expected. To solve this issue, you should first check if the variable is an object before trying to access its properties. 

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