Question

这个问题似乎被问了很多，答案似乎随着时间的推移而改变。我花了一个周末的时间来获取用于Informix的IBM Client SDK在Debian上运行（因为缺少这个过程的大多数方向，所以这需要一个周末来解决。）我现在可以使用isql连接并运行查询到远程Informix服务器- 没问题。现在我需要PHP连接，以便我可以将输出呈现给apache。这个语法;

<?php
try {
    $dbh = new PDO("informix:DSN=InformixDB", "username", "password");
    }
catch (PDOException $e)
    {
    echo $e->getMessage();
    }
 ?>

在网页上产生“找不到驱动程序”错误（这是通用语法 - 我当然填写了信息）。根据我的阅读，需要安装php Informix PDO驱动程序，但我找不到操作方法。过去它是用PECL（？）安装的，现在不是。有人知道吗？我已经安装了以下PHP包;

php5 php5-dev php5-cli

非常感谢任何帮助。

Answer 1

这个答案是我在OpenSuse 12.3中配置和安装Informix PDO的方法我认为它们也应该适用于Debian，除了apache设置如果要添加一些关于Debian的详细信息，请随意编辑或添加评论。

观察：这里没有使用任何ODBC ......只有纯PDO ......

全部以用户root执行 1）下载最新版本的PDO

$ mkdir pdo
$ cd pdo
$ wget http://pecl.php.net/get/PDO_INFORMIX-1.3.1.tgz
--2013-11-12 12:21:51--  http://pecl.php.net/get/PDO_INFORMIX-1.3.1.tgz

2013-11-12 12:21:52 (1.57 MB/s) - `PDO_INFORMIX-1.3.1.tgz' saved [67566/67566]

2）解压缩

$ tar zxf PDO_INFORMIX-1.3.1.tgz
$ cd PDO_INFORMIX-1.3.1/

3）设置你的INFORMIXDIR

$ export INFORMIXDIR=/myifx/csdk

3）执行phpize

$ phpize
Configuring for:
PHP Api Version:         20090626

----------------------------------------------------------------------
Libraries have been installed in:
   /root/pdo/PDO_INFORMIX-1.3.1/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

Build complete.
Don't forget to run 'make test'.

5）安装PDO

$ make install
Installing shared extensions:     /usr/lib64/php5/extensions/

$ ls -ltr /usr/lib64/php5/extensions/ | tail
-rw-r--r-- 1 root root   85720 Jul 16 08:19 sqlite.so
-rw-r--r-- 1 root root   49840 Jul 16 08:19 sqlite3.so
-rw-r--r-- 1 root root   48048 Jul 16 08:19 sockets.so
-rw-r--r-- 1 root root   35760 Jul 16 08:19 xmlreader.so
-rw-r--r-- 1 root root   18928 Jul 16 08:19 tokenizer.so
-rw-r--r-- 1 root root   14864 Jul 16 08:19 sysvshm.so
-rw-r--r-- 1 root root   40224 Jul 16 08:19 zlib.so
-rw-r--r-- 1 root root  102264 Jul 16 08:19 zip.so
-rw-r--r-- 1 root root   52016 Jul 16 08:19 xmlwriter.so
-rwxr-xr-x 1 root root  164722 Nov 12 12:29 pdo_informix.so

6）在PHP上激活PDO

$ cd /etc/php5/conf.d
$ echo "extension=pdo_informix.so" > pdo_informix.ini

7）“激活”Apache的INFORMIX变量。在这里，debian可能会有所不同。

$ cd /etc/sysconfig/

$ tail apache2
#
# If mod_status is used, include extended information about the server, like
# CPU usage, in the status report. It is a server-wide setting, and it can cost
# some performance!
#
APACHE_EXTENDED_STATUS="off"

INFORMIXDIR=/myifx/csdk
LD_LIBRARY_PATH=/myifx/csdk/lib:/myifx/csdk/lib/esql:/myifx/csdk/lib/client:/myifx/csdk/lib/cli:$LD_LIBRARY_PATH

8）重启apache

$ systemctl restart apache2.service

9）然后我可以使用这个PHP访问...

$ cd /srv/www/htdocs
$ cat ifx.php
<?php

$db = new PDO("informix:host=myifx_ifxhom; service=11205; database=xyz; server=idsbkp_soc; protocol=onsoctcp; EnableScrollableCursors=1", "cesar", "cesar");

print "Connection Established!\n\n";

$stmt = $db->query("select * from systables");
$res = $stmt->fetch( PDO::FETCH_BOTH );
$rows = $res[0];
echo "Table contents: $rows.\n";

?>

您可以检查apache是否使用php_info加载了Informix PDO： php_info pdo_informix 并检查apache是否识别出Informix变量： phpinfo environment variables 使用此代码：

$ cat phpinfo.php
<?php

// Show all information, defaults to INFO_ALL
phpinfo();

// Show just the module information.
// phpinfo(8) yields identical results.
phpinfo(INFO_MODULES);

?>

Answer 2

我收到此错误：SQLSTATE=HY000, SQLDriverConnect: -23101 [Informix][Informix ODBC Driver][Informix]Unspecified System Error = -23101

我尝试在apache配置上使用INFORMIXDIR，DB_LOCALE和CLIENT_LOCALE，但不起作用。

Apache Environment

这是我的连接字符串：

$instance = new PDO("informix:host=$host;service=$port;database=$db;server=ol_standard;protocol=onsoctcp;client_locale=en_US.819;db_locale=en_US.819;EnableScrollableCursors=1;OPTIMIZEAUTOCOMMIT=1", "informix", "");
