How can PHP developers prevent threading issues when using LAST_INSERT_ID in MySQL queries within a PHP application?
When using LAST_INSERT_ID in MySQL queries within a PHP application, PHP developers can prevent threading issues by ensuring that the LAST_INSERT_ID value is retrieved immediately after executing the INSERT query within the same database connection. This ensures that the correct value is returned and avoids potential conflicts with other queries that may have been executed in parallel.
// Execute the INSERT query
mysqli_query($connection, "INSERT INTO table_name (column_name) VALUES ('value')");
// Retrieve the LAST_INSERT_ID immediately after executing the INSERT query
$result = mysqli_query($connection, "SELECT LAST_INSERT_ID() as id");
$row = mysqli_fetch_assoc($result);
$last_insert_id = $row['id'];
