If you use PHP5, the currently advised approach to natively (ie, without using a third party
library) interfacing with sqlite3 databases is through the use of a PDO object:
<?php
$dbh = new PDO('sqlite:yourdatabase.db');
?>
Any execution of functions and commands supported by sqlite3 can then be called through the PDO
query and exec functions. For instance, a broad select would be achieved as follows:
<?php
foreach($dbh->query('SELECT * FROM table WHERE column = criterium') as $row)
{
ãforeach($row as $key=>$val)
ã {
ã ã// PDO has no built in fetch_assoc equivalent
ã ãif(!is_numeric($key)) print "$key: $val\n";
ã }
}
?>
when done consulting or administrating a database that relies on PDO access, it is generally a good
idea to either issue a
<?php $dbh = null; ?>
or
<?php unset($dbh); ?>
statement, as the PDO class does not come with a function for closing a connection, and so any PDO
connection will sit idle until you explicitly dispose of it.
