How to insert multiple rows from array using CodeIgniter framework?

I'm passing a large dataset into a MySQL table via PHP using insert commands and I'm wondering if it's possible to insert approximately 1000 rows at a time via a query other than appending each value on the end of a mile-long string and then executing it. I am using the CodeIgniter framework so its functions are also available to me.

Do you mean like this?

Assembling one INSERT statement with multiple rows is much Faster in MySQL Examples than one INSERT statement per row.

That said, it sounds like you might be running into string-handling problems in PHP, which is really an algorithm problem, not a language one. Basically, when working with large strings, you want to minimize unnecessary copying. Primarily, this means you want to avoid concatenation. The fastest and most memory-efficient way to build a large string, such as for inserting hundreds of rows at one, is to take advantage of the implode() function and array assignment.
$sql = array();
foreach( $data as $row ) {
    $sql[] = '("'.mysql_real_escape_string($row['text']).'", '.$row['category_id'].')';
mysql_query('INSERT INTO table (text, category) VALUES '.implode(',', $sql));

The advantage of this approach is that you don't copy and re-copy the SQL statement you've so far assembled with each concatenation; instead, PHP does this once in the implode() statement. This is a big win.

If you have lots of columns to put together, and one or more are very long, you could also build an inner loop to do the same thing and use implode() to assign the values clause to the outer array.

I don't recommend using mysql_* functions, this has been deprecated since PHP 5.5 and removed in PHP 7.0.
The insertBatch() is maintained and available on multiple drivers supported by CodeIgniter4.

To insert multiple rows from array using the CodeIgniter framework, you can use the insert_batch() function of the CI_DB class. The insert_batch() function takes an array of arrays as its argument. Each array in the array represents a row of data to be inserted into the database. The insert_batch() function will then execute a single SQL query to insert all of the rows into the database.

For example, the following code would insert two rows into the user's table:

PHP Code:
$data = [
        'name' => 'John Doe',
        'email' => '[email protected]',
        'password' => 'password123'
        'name' => 'Jane Doe',
        'email' => '[email protected]',
        'password' => 'password456'


The insert_batch() function will return the number of rows that were successfully inserted into the database. If any rows were not inserted, the function will return an error message.
