How can developers avoid ignoring text input in PHP forms when saving data to a database?

Developers can avoid ignoring text input in PHP forms when saving data to a database by checking if the input is not empty before inserting it into the database. This can be done using the `empty()` function or by checking the length of the input using `strlen()`. By ensuring that the input is not empty, developers can prevent unintentionally saving incomplete or missing data into the database. 

// Check if the text input is not empty before saving it to the database
if (!empty($_POST['text_input'])) {
    $text_input = $_POST['text_input'];
    // Insert the text input into the database
    // Add your database connection and query here
} else {
    // Handle the case where the text input is empty
    echo "Text input cannot be empty";
}
