What potential issue can arise from not checking if the parent object is present in the PHP script?

If the parent object is not checked for presence in a PHP script, it can lead to errors or unexpected behavior if the parent object is not initialized or does not exist. To solve this issue, you should always check if the parent object is present before attempting to access its properties or methods. 

// Check if the parent object is present before accessing its properties or methods
if(isset($parentObject)) {
    // Access parent object properties or methods here
    $parentObject->someMethod();
} else {
    // Handle the case where the parent object is not present
    echo "Parent object is not initialized.";
}
