Ok, I don't use SQLite in PHP or elsewhere, but I just spent a lot of
time researching the available SQLite interfaces in PHP, so pardon me
if some of the below is already self-explanatory to you; it wasn't to
me and I want to write it out to make sure I got it right.
PHP offers two built-in interfaces for accessing SQLite databases: a
procedural API and an object-oriented interface using PDO (PHP Data
Objects). If you install the php5 port with the +sqlite3 variant, you
get both of them. The procedural API is documented here and includes
such functions as sqlite_open():
The PDO interface is documented here and involves you using a PDO
The catch is that the procedural API is only for SQLite 2 databases.
The only built-in interface for using SQLite 3 databases is via PDO.
There is also a PECL extension, php-sqlite3, which was developed
during 2008, currently at version 0.6. This is what the php5-sqlite3
port installs. But it does not provide the sqlite3_open function you
are seeking. Rather, it gives you an object-oriented interface based
around three classes: SQLite3, SQLite3Stmt and SQLite3Result. It is
described here, rather incompletely, notably the installation
instructions are totally missing:
There is also the PECL page about the extension, but it doesn't have
any documentation at all:
As far as I can tell, to use it, you add the line "extension =
sqlite3.so" to your php.ini.
I finally found the sqlite3_open function you're trying to use in
another extension which is also called php-sqlite3. This one was
developed from 2005 to 2007 and is currently at version 0.5:
We don't have a MacPorts port for this extension.
So after all that, if this is a web app you are making, then I
suggest you use the built-in PDO SQLite3 interface since it is well-
supported and doesn't require installing an extension. If this is
someone else's web app and you're not in a position to rewrite it to
use PDO SQLite3 and you can't convince its developer to do so, then
you'll have to either write a port for this earlier php-sqlite3
extension (though I'm not sure what we would call the port) or
install it manually.
