How can circular referencing issues between tables be resolved in PHP when using SQL 5 for database queries?

Circular referencing issues between tables can be resolved by carefully designing the database schema to avoid such dependencies. If circular referencing is unavoidable, you can use foreign key constraints with the `ON DELETE CASCADE` option to automatically delete related records when a parent record is deleted. 

// Example code snippet to create tables with foreign key constraints to resolve circular referencing issues
$sql = "CREATE TABLE table1 (
    id INT PRIMARY KEY,
    name VARCHAR(50)
);

CREATE TABLE table2 (
    id INT PRIMARY KEY,
    table1_id INT,
    FOREIGN KEY (table1_id) REFERENCES table1(id) ON DELETE CASCADE
);";
