Remotely connect to Oracle using PHP in Linux

The OCI package is required for PHP to remotely connect to Oracle. This package is provided by oracle. You can directly install the Oracle InstantClient to obtain this package.

Easy to install
Rpm-Uvh oracle-instantclient-basic-10.2.0.3-1.i386.rpm
Rpm-Uvh oracle-instantclient-devel-10.2.0.3-1.i386.rpm

After the installation is complete, you can view the installed library file in/usr/lib/oracle.

After the need to re-compile php, coupled with -- with-oci8 = share, instantclient,/usr/lib/oracle/10.2.0.3/client/lib parameters, as follows:
./Configure -- with-mysql -- with-apxs2 =/usr/local/apache2/bin/apxs -- with-oci8 = share, instantclient,/usr/lib/oracle/10.2.0.3/client/lib

Test code:

<? Php
$ Conn = OCILogon ('username', 'Password', '192. 168.1.2/test ');
If (! $ Conn ){
$ E = oci_error ();
Print htmlentities ($ e ['message']);
Exit;
}
Else
{
Echo "Successfully connected to Oracle! \ N ";
Ocilogoff ($ conn );
}
?>

There is also the oci compilation parameters in php. You can see the README of ext/oci8 in the php original code Directory, which has an explanation.
