What are the potential pitfalls of using INSERT statements with WHERE clauses in PHP?

When using INSERT statements with WHERE clauses in PHP, it is important to note that INSERT statements are typically used to add new records to a database, while WHERE clauses are used with SELECT, UPDATE, and DELETE statements to filter records. Using a WHERE clause with an INSERT statement can lead to unexpected behavior or errors. To resolve this issue, you should use the appropriate SQL statement for the task at hand, such as using an UPDATE statement instead of an INSERT statement with a WHERE clause.

// Incorrect usage of INSERT with WHERE clause
$sql = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2') WHERE condition";

// Correct usage of UPDATE statement
$sql = "UPDATE table_name SET column1 = 'new_value1', column2 = 'new_value2' WHERE condition";
