How Can CodeIgniter's `insert_batch()` Function Improve MySQL Bulk Row Insertion Efficiency?

Efficient Bulk Row Insertion in MySQL Using CodeIgniter

When inserting large volumes of data into MySQL tables using PHP, performance considerations become crucial. Rather than using individual INSERT statements for each row, it is more efficient to insert multiple rows simultaneously.

CodeIgniter, a popular PHP framework, provides various methods for database manipulation. For bulk row insertion, it is recommended to use the insert_batch() function.

Example:

$data = [
    ['text' => 'row1_text', 'category_id' => 1],
    ['text' => 'row2_text', 'category_id' => 2],
    // ... additional rows
];

$this->db->insert_batch('table', $data);

Advantages of using insert_batch():

• Reduces network overhead by sending a single query instead of multiple queries.
• Improves performance by reducing the number of round-trips to the database.
• Avoids potential string concatenation issues in PHP, which can limit the number of rows that can be inserted at once.

Additional considerations:

• Ensure that your database can handle the amount of data being inserted in a single query.
• Use data preparation methods like mysql_real_escape_string() to prevent SQL injection attacks.
• Monitor your database performance to identify any potential bottlenecks or optimizations.
