PHP 5.4.32 Released

Fonctions Informix (PDO_INFORMIX)

Introduction

PDO_INFORMIX est un pilote qui implémente l'interface de PHP Data Objects (PDO) pour autoriser l'accès à PHP aux bases de données Informix.

Installation

Pour compiler l'extension PDO_INFORMIX, le SDK Client Informix 2.81 UC1 ou supérieur doit être installé sur le même système que PHP. Le SDK Client Informix est disponible sur le » Site de Support IBM Informix.

PDO_INFORMIX est une extension » PECL, alors suivez les instructions dans Installation d'extensions PECL pour installer l'extension PDO_INFORMIX. Écrivez la commande configure pour pointer au chemin de vos fichiers d'en-têtes SDK Client Informix ainsi que les bibliothèques comme suit :

   bash$ ./configure --with-pdo-informix=/path/to/SDK[,shared]
La commande configure utilise par défaut la variable d'environnement INFORMIXDIR.

Curseurs flottants

PDO_INFORMIX supporte les curseurs flottants; cependant, ils ne sont pas activés par défaut. Pour activer le support des curseurs flottants, vous devez soit fixer ENABLESCROLLABLECURSORS=1 dans les configurations de la connexion ODBC correspondante dans odbc.ini ou passer la clause EnableScrollableCursors=1 dans la chaîne de caractères de connexion DSN.

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!

I noticed that SQLite is installed by php by default...oh and it happens to use PDO. So dont forget to use --without-sqlite.

My successful config looks like this:

./configure --with-mysql --with-apxs=/usr/local/apache/bin/apxs --with-curl --with-xsl --disable-pdo --without-sqlite

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

I've just built PHP 5.2.11 with pdo_informix support on Slackware 13.0.  I had to use the following options in order to disable pdo from being compiled in (notice the difference in the --without-pdo-sqlite option from previous post):

--disable-pdo option --without-pdo-sqlite option

I also could not use the --with-sigchild option which caused problems with phpize.

This fixed the informix -11001 error that I was getting.  I was also getting an informix -23101 error (something about locale mismatches), but it was because I was not completely removing the compiled in pdo support.

I then had to;

rm -rf /usr/lib/php/.channels
pear update-channels
pecl install --alldeps pdo_informix pdo_mysql pdo_sqlite.

There were other, smaller issues, but that is the lion's share.

tip: in fedora 16 you must set INFORMIXDIR  in /etc/sysconfig/httpd
example:
INFORMIXDIR=/home/informix
export INFORMIXDIR
