What's New

Two new kits for CSWS_PHP V1.3 are now available – one for OpenVMS I64 Version 8.2 and higher, and one for OpenVMS Alpha 7.3-2 and higher. For more information about PHP, see http://www.php.net/.

New features included in CSWS_PHP V1.3 are as follows:

· CSWS_PHP V1.3 is intended to work with the Secure Web Server Version 2.1 and 1.3-1. It does not work with SWS Version 2.0.

· Based on PHP 4.3.10. (CSWS_PHP V1.2-1 was based on PHP 4.3.2.)

PHP 4.3.10 includes over 30 non-critical bug fixes and addresses several serious security issues. See http://www.php.net/release_4_3_10.php for more information.

· PHP_GD extension, which allows you to create and manipulate image files in a variety of different image formats, including gif, png, jpg, wbmp, and xpm. PHP can also output image streams directly to a browser. See http://us2.php.net/manual/en/ref.image.php for more information.

New features included in CSWS_PHP V1.2-1 are as follows:

· CSWS_PHP V1.2-1 works with the Secure Web Server Version V1.3-1.

· Based on PHP 4.3.2.

· Includes MySQL extension, which allows you to access MySQL database servers. More information about MySQL can be found at http://www.mysql.com/.

· Includes OpenVMS extension, which performs several functions such as converting filenames and showing uptime. See the OpenVMS sample script for more information.

· Includes updated OpenSSL extension, based on HP SSL Version 1.2 for OpenVMS (OpenSSL 0.9.7D).

Software Prerequisites

Documentation

For more information about PHP, see http://www.php.net/.

Installing CSWS_PHP for OpenVMS

Important: If you are upgrading from an earlier version of CSWS_PHP and you modified PHP.INI, copy the file to another directory before you begin the installation. After the installation is complete, compare your old PHP.INI with the newly installed version and modify the new file as necessary.

Before you install CSWS_PHP (or any optional module), shut down the Secure Web Server. You can restart the server when the installation is complete.

To install the CSWS_PHP for HP Secure Web Server for OpenVMS kit, enter the following command.

Note: You must install the CSWS_PHP kit into the same device and directory where you installed the HP Secure Web Server for OpenVMS.

For example:

$ SHOW LOGICAL APACHE$ROOT

"APACHE$ROOT" = "DISK1:[WEB_SERVER.APACHE.SPECIFIC.hostname.]

= "APACHE$COMMON:"

1 "APACHE$COMMON" = "DISK1:[WEB_SERVER.APACHE.]

$ PRODUCT INSTALL CSWS_PHP/DESTINATION=DISK1:[WEB_SERVER]

For a description of PRODUCT INSTALL commands, see the POLYCENTER Software Installation Utility User's Guide.

As the installation procedure for CSWS_PHP 1.3 progresses, the system displays the following information.

The following product has been selected:

CPQ AXPVMS CSWS_PHP V1.3 Layered Product

Do you want to continue? [YES]

The following product has been installed:

CPQ AXPVMS CSWS_PHP V1.3 Layered Product

CPQ AXPVMS CSWS_PHP V1.3

Post-installation tasks are required for PHP for OpenVMS.

The release notes give detailed directions.

This information is a brief checklist.

This installation modifies APACHE$ROOT:[CONF]HTTPD.CONF to

enable MOD_PHP. Check HTTPD.CONF for accuracy. The line

"Include /apache$root/conf/mod_php.conf" should be the only

difference. Also study the MOD_PHP configuration file

(APACHE$ROOT:[CONF]MOD_PHP.CONF) for options required for your

site.

The Apache server must be shut down and restarted to make these

changes to HTTPD.CONF file take place. Test that MOD_PHP

is working by accessing the sample script from a browser:

http://<your web server host>/php/php_rules.php

Thank you for using Apache for OpenVMS.

After the installation is complete, start the Secure Web Server by entering the following command:

    $ @SYS$STARTUP:APACHE$STARTUP

Removing CSWS_PHP for HP Secure Web Server for OpenVMS

You can remove the CSWS_PHP kit by using the PRODUCE REMOVE command. The HP Secure Web Server must be shut down before you remove CSWS_PHP.

To remove CSWS_PHP, enter the following commands:

$ @SYS$STARTUP:APACHE$SHUTDOWN

$ PRODUCT REMOVE CSWS_PHP

The PRODUCT REMOVE command removes all files created by this installation. It also attempts to remove the directories defined by this installation.

Using Extensions

CSWS_PHP 1.3 includes the extensions listed in the PHP.INI file shown below. There are two ways to load a PHP extension: using the dl() function and using the PHP.INI file. These methods are as follows:

· The dl() function allows the loading of extensions within a PHP script if the extension resides in the default extension_dir. Extension_dir is defined as PHP_ROOT:[EXTENSIONS] directory (APACHE$COMMON:[PHP.EXTENSIONS]).

· The PHP.INI file provided with the CSWS_PHP kit resides in the PHP_ROOT:[000000] directory (APACHE$COMMON:[PHP]). PHP.INI contains the extension statement to automatically load the extension for every PHP script executed. To enable the loading of the extension for every PHP script, uncomment the "extension=" statement as shown in the following example, and restart the Secure Web Server.

PHP.INI

;

; Uncomment for the automatic loading of extensions

;

;extension=php_bcmath.exe

;extension=php_bzip2.exe

;extension=php_calendar.exe

;extension=php_ctype.exe

;extension=php_dba.exe

;extension=php_exif.exe

;extension=php_ftp.exe
;extension=php_gd.exe

;extension=php_iconv.exe

;extension=php_ldap.exe

;extension=php_mhash.exe

;extension=php_openssl.exe

;extension=php_openvms.exe

;extension=php_oracle.exe

;extension=php_pcre.exe

;extension=php_posix.exe

;extension=php_session.exe

;extension=php_sockets.exe

;extension=php_xml.exe

;extension=php_zip.exe

;extension=php_zlib.exe

ODBC Extension

The ODBC extension works with any ODBC V2.5 capable server. The ODBC.PHP script works with Attunity Connect "On Platform" Package for OpenVMS Alpha using the RMS demo.

Add the following lines to the beginning of the APACHE$COMMON:[000000]LOGIN.COM file to enable the script to work with Attunity Connect:

$ !

$ ! Run the Attunity login if we find it

$ !

$ IF F$SEARCH ("NAVROOT:[BIN]NAV_LOGIN.COM") .NES. ""

$ THEN

$ @NAVROOT:[BIN]NAV_LOGIN.COM

$ DEFINE APACHE$ODBC_SHR ODNAVSHR

$ DEFINE APACHE$ODBC_PFX NV

$ ENDIF

The two logicals required to make the ODBC extension functional are APACHE$ODBC_SHR and APACHE$ODBC_PFX. These logicals are defined as follows:

· APACHE$ODBC_SHR
This logical defines the ODBC shareable image to be used for the ODBC access.

· APACHE$ODBC_PFX
This logical defines, if needed, any ODBC API prefix.

OCI Extension

Add the following lines to the beginning of the file APACHE$COMMON:[000000]LOGIN.COM:

For Oracle 8i:

$ !

$ ! Define the OCI extension logicals if we find the OCI client shareable

$ !

$ IF F$SEARCH ("ORA_ROOT:[UTIL]ORACLIENT_V817.EXE") .NES. ""

$ THEN

$ DEFINE APACHE$OCI_SHR ORA_ROOT:[UTIL]ORACLIENT_V817.EXE

$ ENDIF

For Oracle 9i:

$ !

$ ! Define the OCI extension logicals if we find the OCI client shareable

$ !

$ IF F$SEARCH ("ORA_ROOT:[LIB32]LIBCLNTSH.SO") .NES. ""

$ THEN

$ DEFINE APACHE$OCI_SHR ORA_ROOT:[LIB32]LIBCLNTSH.SO

$ ENDIF

The two logicals required to make the OCI extension functional are APACHE$OCI_SHR and APACHE$OCI_PFX. These logicals are defined as follows:

· APACHE$OCI_SHR
This logical defines the OCI8 shareable image to be used for the OCI8 access.

· APACHE$OCI_PFX
This logical defines, if needed, any OCI8 API prefix.

Release Notes

This section contains notes on the current release of CSWS_PHP.

· PHP$ logical names changed to APACHE$

In Version 1.2 and higher of CSWS_PHP for HP Secure Web Server, the prefix of the PHP$ logical names was changed to APACHE$. This change allows other Secure Web Server-based scripting languages (such as Perl) to use the database connectivity features. The changed logical names are as follows:

Old Logical Name New Logical Name
(1.0 and 1.1) (1.2 and higher)

       PHP$ODBC_SHR            APACHE$ODBC_SHR
       PHP$ODBC_PFX             APACHE$ODBC_PFX
       PHP$OCI_SHR                APACHE$OCI_SHR
       PHP$OCI_PFX                 APACHE$OCI_PFX

· Add logical names to PHP_SETUP.COM for extended file name support

If you are using CSWS_PHP alone or with HP Secure Web Server Version 1.3 or higher, and you have ODS-5 files with extended file names such as grab_globals.lib.php (which has multiple dots), the files will not be processed correctly.

To solve this problem, add the following logical definitions to the end of PHP_SETUP.COM located in APACHE$COMMON:[000000]:

$ DEFINE /NoLog DECC$EFS_CASE_PRESERVE ENABLED

$ DEFINE /NoLog DECC$EFS_CASE_SPECIAL ENABLED

$ DEFINE /NoLog DECC$EFS_CHARSET ENABLED

$ DEFINE /NoLog DECC$FILE_SHARING ENABLED

Using the commands SET PROCESS/PARSE=EXTENDED and SET PROCESS/PARSE=EXTENDED/CASE=SENSITIVE does not work in this situation.

· Configuring CSWS_PHP not required

During the installation, the file PHP_SETUP.COM is added to the APACHE$ROOT directory, and an include for MOD_PHP.CONF is added to the end of HTTPD.CONF. When you start the Secure Web Server, PHP_SETUP.COM is run and PHP is loaded into the server. You do not need to configure CSWS_PHP.

· PHP DNS functions supported only with TCP/IP Services for OpenVMS

This version of CSWS_PHP supports the CHECKDNSRR and GETMXRR functions only on systems using HP TCP/IP Services for OpenVMS. These functions may be supported with other TCP/IP products in a future CSWS_PHP kit.

· PHP LINK functions not supported

This version of CSWS_PHP does not support the LINK, LINKINFO, SYMLINK, and READLINK functions. These functions may be supported in a future CSWS_PHP kit.
