LXVIII. Informix Functions (PDO_INFORMIX)

Úvod

PDO_INFORMIX is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to Informix databases.

Instalace

To build the PDO_INFORMIX extension, the Informix Client SDK 2.81 UC1 or higher must be installed on the same system as PHP. The Informix Client SDK is available from the » IBM Informix Support Site.

PDO_INFORMIX is a » PECL extension, so follow the instructions in 7 – „Installation of PECL extensions“ to install the PDO_INFORMIX extension. Issue the configure command to point to the location of your Informix Client SDK header files and libraries as follows:


   bash$ ./configure --with-pdo-informix=/path/to/SDK[,shared]

The configure command defaults to the value of the INFORMIXDIR environment variable.

Scrollable cursors

PDO_INFORMIX supports scrollable cursors; however, they are not enabled by default. To enable scrollable cursor support, you must either set ENABLESCROLLABLECURSORS=1 in the corresponding ODBC connection settings in odbc.ini or pass the EnableScrollableCursors=1 clause in the DSN connection string.

Solved the issue with PHP 5.2.4 and others.



The embedded PDO in php since 5.1+ is INCOMPATIBLE with the latest PDO_MYSQL and PDO_INFORMIX, etc.  I just spent 2 days working on this.  This solution works on numerous versions of Linux I've tried as well as SunOS and HPUX.



The basic issue, getting this message when running PHP with PDO and trying

to get PDO_INFORMIX working, but having a version conflict:



"PHP Fatal error: PDO: driver informix requires PDO API version 20060409;

this is PDO version 20060511 in Unknown on line 0"



The "embedded" PDO that is within PHP since version 5.1 CONFLICTS with the

PDO the  PEAR/PECL modules are expecting.



1) Rebuild PHP with no pdo (--disable-pdo) (and you can't have

  any stuff like --with-mysql-pdo, either)

2) Then use PEAR/PECL to install PDO:  pear install pdo

3) then use PEAR/PECL to install PDO_INFORMIX:

              pear install --alldeps pdo_informix

4) make sure your php.ini extensions_dir points to the directory

   where these are placed

5) then add these references to php.ini:

    extensions=pdo.so

    extensions=pdo_informix.so

    extensions=pdo_mysql.so (etc.)



6) run php -v now and you should not see any errors.



7) run "pear list" and "pecl list" to see the installed modules



8) run php -i |egrep "pdo|PDO" to see:



php -i |egrep "pdo|PDO"

Configure Command =>  './configure'  '--disable-pdo'

'--with-apxs2=/usr/local/apache2/bin/apxs' '--with-openssl=/usr'

'--enable-force-cgi-redirect' '--with-gd' '--with-jpeg-dir=/usr/lib'

'--with-zlib' '--enable-bcmath' '--enable-mbstring=all' '--with-curl'

PDO

PDO support => enabled

PDO drivers => mysql, informix

pdo_informix

pdo_informix support => enabled

pdo_mysql

PDO Driver for MySQL, client library version => 5.0.51a



I would have tried the embedded PDO and then also --with-informix-pdo=shared but as an earlier post here showed, the --with-informix... is unknown.  Please correct my mistake if I am mistyping it.



GOOD LUCK!

Take care, with php-5.2.4 --with-pdo-informix=shared,/home/informix

 doesn't work, just says: 

Notice: Following unknown configure options were used:

--with-pdo-informix=shared,/home/informix

IIUG (International Informix Users Group) has made the Windows driver available on its site (wwww.iiug.org), as it is not included in v5.1.2.
