What steps can be taken to troubleshoot a "Fatal error: Attempt to assign property on null" message in PHP?

To troubleshoot a "Fatal error: Attempt to assign property on null" message in PHP, you need to ensure that the variable you are trying to access is not null before attempting to assign a property to it. You can do this by checking if the variable is set using isset() or !empty() before trying to access its properties.

// Check if the variable is not null before assigning a property
if(isset($variable)) {
    $variable->property = 'value';
} else {
    // Handle the case where the variable is null
    echo 'Variable is null';
}
