Normally I would avoid getting into this sort of argument ( The 'OMG someone on
teh internets are
wrong!!' argument)
But in this case, the solution ( still the first result in a google search) is
far more efficient than
closing a connection so you can insert into another table.
You are correct in that the example given doesn't do exactly what you are
trying to do, but a little
imagination stretches it into exactly what you want.
Exhibit A:
Here I have created 2 test tables in 'testdb' and inserted an A into the first.
mysql> create database testdb
-> ;
Query OK, 1 row affected (0.08 sec)
mysql> connect testdb;
Connection id: 72
Current database: testdb
mysql> create table test1( t1 VARCHAR(1) );
Query OK, 0 rows affected (0.13 sec)
mysql> create table test2( t2 VARCHAR(1) );
Query OK, 0 rows affected (0.00 sec)
mysql> insert into test1 VALUES( 'A' ); insert into test2 VALUES('B');
Query OK, 1 row affected (0.08 sec)
Query OK, 1 row affected (0.00 sec)
mysql> select * from test1; select * from test2;
+------+
| t1 |
+------+
| A |
+------+
1 row in set (0.02 sec)
+------+
| t2 |
+------+
| B |
+------+
1 row in set (0.00 sec)
###
As you can see, a single statement is being used to insert into multiple rows,
a clue this can be
done with a script as well... but I digress... we will get to that.
Exhibit B
Here I have copied the final script from the page that I said contained the
answer.
Source is: http://www.hiteshagrawal.com/mysql/mysql-batch-insert-using-php
I've changed 2 things:
1. The connection info ( except the password obviously ) corresponds to my test
setup
2. The query was changed to make sense for my test setup
<?php
$batchconnection = new mysqli('localhost', 'root', 'hunter2', 'testdb');
if ($batchconnection->connect_error) {
echo "Error Occurred While Connection To DataBase";
}
$sqlStatements = "insert into test1(t1) values('1');insert into test2(t2)
values('2');";
$sqlResult = $batchconnection->multi_query($sqlStatements);
if($sqlResult == true) {
echo "Successfully Inserted Records";
} else {
echo "Some Error Occured While Inserting Records";
}
?>
So then we execute it:
co...@somethingelse:~/phpcrap$ ./tester.php
Successfully Inserted recordsco...@somethingelse:~/phpcrap$
That looks promising.
Exhibit C
Finally, lets see what our database looks like
mysql> select * from test1; select * from test2;
+------+
| t1 |
+------+
| A |
| 1 |
+------+
2 rows in set (0.00 sec)
+------+
| t2 |
+------+
| B |
| 2 |
+------+
2 rows in set (0.00 sec)
Oh wow... it worked!
Since it is your script, the way you ultimately do it is your option...
I would suggest that you do not disconnect between inserts, this is terribly
inefficient.
