Informix (PDO_INFORMIX) İşlevleri


PDO_INFORMIX, PHP Veri Nesneleri Arayüzünün (PDO) Informix veritabanlarına erişimini mümkün kılmak için gerçeklenmiş bir sürücüdür.


PDO_INFORMIX eklentisini kurmak için PDO_INFORMIX'i derlediğiniz makineye Informix Client SDK 2.81 UC1 veya üstünü kurmuş olmalısınız. Informix Client SDK » IBM Informix destek sitesinden temin edilebilir.

PDO_INFORMIX bir » PECL eklentisi olduğundan kurulum için PECL eklentilerinin kurulması bölümüne bakınız. Informix Client SDK başlık dosyalarının bulunduğu yeri belirtmek için configure komutunu şöyle kullanabilirsiniz:

   bash$ ./configure --with-pdo-informix=/bir/yol/SDK[,shared]
configure komutu öntanımlı değer olarak INFORMIXDIR ortam değişkenindeki değeri kullanır.

Kaydırılabilir göstericiler

PDO_INFORMIX kaydırılabilir göstericileri desteklemekle birlikte öntanımlı olarak etkin değildir. Kaydırılabilir gösterici desteğini etkin kılmak için odbc.ini dosyasındaki ilgili ODBC bağlantı ayarlarına ENABLESCROLLABLECURSORS=1 atamalı ya da DSN bağlantı dizgesinde EnableScrollableCursors=1 yan tümcesini belirtmelisiniz.

Informix PDO needs the INFORMIXDIR system variable available to the script running under the webserver, in my case apache 2.4.

Using setenv did not work, so I added in the systemd startup script /lib/systemd/system/apache2.service the following:


in the [Service] section.

Of course, the installation directory of your informix libraries may be different than /opt/Informix_Software_Bundle....

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: (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 support => enabled
PDO drivers => mysql, informix
pdo_informix support => enabled
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.

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

In case that you loaded the extension, in solaris systems, and you are getting something similar to this:
PHP Warning: PHP Startup: Unable to load dynamic library '/opt/php547/lib/php/extensions/no-debug-non-zts-20100525/' - php: fatal: DF_1_NOOPEN tagged object may not be dlopen()'ed in Unknown on line 0

In this case set the following Environment variables:
export INFORMIXDIR=/path/to/Informix/CSDK/

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.
