>&#13;     The Informix driver for Informix (IDS) 7.x, SE 7.x, Universal
     Server (IUS) 9.x and IDS 2000 is implemented in "ifx.ec" and
     "php3_ifx.h" in the informix extension directory.  IDS 7.x support
     is fairly complete, with full support for BYTE and TEXT
     columns. IUS 9.x support is partly finished: the new data types
     are there, but SLOB and CLOB support is still under construction.

       You need a version of ESQL/C to compile the PHP Informix driver.
       ESQL/C versions from 7.2x on should be OK. ESQL/C is now part of
       the Informix Client SDK.
      </P
><P
>&#13;       Make sure that the "INFORMIXDIR" variable has been set, and that
       $INFORMIXDIR/bin is in your PATH before you run the "configure"
       script.

   Make sure that the Informix environment variables INFORMIXDIR and
   INFORMIXSERVER are available to the PHP ifx driver, and that the
   INFORMIX bin directory is in the PATH. Check this by running a
   script that contains a call to <A
HREF="function.phpinfo.html"
><B
CLASS="function"
>phpinfo()</B
></A
>
   before you start testing. The <A
HREF="function.phpinfo.html"
><B
CLASS="function"
>phpinfo()</B
></A
>
   output should list these environment variables. This is <TT
CLASS="constant"
><B
>TRUE</B
></TT
> for
   both CGI php and Apache mod_php. You may have to set these
   environment variables in your Apache startup script.
  </P
><P
>&#13;   The Informix shared libraries should also be available to the
   loader (check LD_LIBRARY_PATH or ld.so.conf/ldconfig).

>Some notes on the use of BLOBs (TEXT and BYTE columns): </B
>
   BLOBs are normally addressed by BLOB identifiers.  Select queries
   return a "blob id" for every BYTE and TEXT column.  You can get
   at the contents with "string_var = ifx_get_blob($blob_id);" if
   you choose to get the BLOBs in memory (with :
   "ifx_blobinfile(0);").  If you prefer to receive the content of
   BLOB columns in a file, use "ifx_blobinfile(1);", and
   "ifx_get_blob($blob_id);" will get you the filename.  Use normal
   file I/O to get at the blob contents.
  </P
><P
>&#13;   For insert/update queries you must create these "blob id's"
   yourself with "<A
HREF="function.ifx-create-blob.html"
><B
CLASS="function"
>ifx_create_blob()</B
></A
>;". You then
   plug the blob id's into an array, and replace the blob columns
   with a question mark (?) in the query string.  For
   updates/inserts, you are responsible for setting the blob
   contents with <A
HREF="function.ifx-update-blob.html"
><B
CLASS="function"
>ifx_update_blob()</B
></A
>.
  </P
><P
>&#13;   The behaviour of BLOB columns can be altered by configuration
   variables that also can be set at runtime :
  </P
><P
>&#13;   configuration variable : ifx.textasvarchar
  </P
><P
>&#13;   configuration variable : ifx.byteasvarchar
  </P
><P
>&#13;   runtime functions :
  </P
><P
>&#13;   ifx_textasvarchar(0) : use blob id's for select queries with TEXT
   columns
  </P
><P
>&#13;   ifx_byteasvarchar(0) : use blob id's for select queries with BYTE
   columns
  </P
><P
>&#13;   ifx_textasvarchar(1) : return TEXT columns as if they were
   VARCHAR columns, so that you don't need to use blob id's for
   select queries.
  </P
><P
>&#13;   ifx_byteasvarchar(1) : return BYTE columns as if they were
   VARCHAR columns, so that you don't need to use blob id's for
   select queries.
  </P
><P
>&#13;   configuration variable : ifx.blobinfile
  </P
><P
>&#13;   runtime function :
  </P
><P
>&#13;   ifx_blobinfile_mode(0) : return BYTE columns in memory, the blob
   id lets you get at the contents.
  </P
><P
>&#13;   ifx_blobinfile_mode(1) : return BYTE columns in a file, the blob
   id lets you get at the file name.
  </P
><P
>&#13;   If you set ifx_text/byteasvarchar to 1, you can use TEXT and BYTE
   columns in select queries just like normal (but rather long)
   VARCHAR fields.  Since all strings are "counted" in PHP, this
   remains "binary safe".  It is up to you to handle this
   correctly. The returned data can contain anything, you are
   responsible for the contents.
  </P
><P
>&#13;   If you set ifx_blobinfile to 1, use the file name returned by
   ifx_get_blob(..) to get at the blob contents.  Note that in this
   case YOU ARE RESPONSIBLE FOR DELETING THE TEMPORARY FILES CREATED
   BY INFORMIX when fetching the row.  Every new row fetched will
   create new temporary files for every BYTE column.
  </P
><P
>&#13;   The location of the temporary files can be influenced by the
   environment variable "blobdir", default is "." (the current
   directory).  Something like : putenv(blobdir=tmpblob"); will ease
   the cleaning up of temp files accidentally left behind (their
   names all start with "blb").
