How can PHP developers handle special characters like double quotes in form input values to avoid truncation?

Special characters like double quotes in form input values can cause truncation issues when storing them in a database or processing them in PHP. To handle this, developers can use the addslashes() function to escape special characters before inserting the input values into the database. This function adds a backslash before special characters, including double quotes, to prevent any issues with the input values. 

// Get form input value
$input_value = $_POST['input_field'];

// Escape special characters
$escaped_value = addslashes($input_value);

// Insert escaped value into database
$query = "INSERT INTO table_name (column_name) VALUES ('$escaped_value')";
// Execute query
