Debian上的PHP和Informix – 如何安装/配置PDO

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让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？我安装了以下PHP包;

PHP5 PHP5-dev PHP5-cli

很感谢任何形式的帮助.

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 set.
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ODBC ……只有纯PDO ……

所有都是用户root执行的
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
Zend Module Api No:      20090626
Zend Extension Api No:   220090626
configure.in:3: warning: prefer named diversions
configure.in:3: warning: prefer named diversions

3)执行./configure

哎呀..这是Opensuse的错误,不确定Debian是否也会发生…
需要在./configure中更正PHP_pdo_driver.h的路径并重新运行.

$grep PHP_pdo_driver.h configure
if test -f $abs_srcdir/include/PHP/ext/pdo/PHP_pdo_driver.h; then
elif test -f $abs_srcdir/ext/pdo/PHP_pdo_driver.h; then

as_fn_error $? "Cannot find PHP_pdo_driver.h." "$LINENO" 5

$locate PHP_pdo_driver.h

4)编译PDO

----------------------------------------------------------------------
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,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：

并检查apache是否识别出Informix变量：

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);

?>
