Hello all,
I am fairly new to Linux/PHP so please bear with me. I have an awfully
awkward problem to solve - a stop gap solution for the next 6 months until
we have out in-house servers set up and running. I also have a very short
timeframe to sort this out. I am using PHP on a remotely hosted Linux web
server to build my website, however I have been given a MS Access database
to use! Despite my best efforts (and two days Google trawling) I haven't
found a suitable solution so I am turning to your collective knowledge.
First things first - I do not run the server and cannot install any new
tools on to it (I cannot access the folders above my web root). There are
lots of suggestions on the net about installing MDBTools and UnixODBC RPM
(http://bryanmills.net:8086/archives/000099.html) - but that involves the
admin who won't do it! I can, of course, put scripts that may help in the
actual web folder and reference them if anyone has any ideas.
I know I must use a DSN-less connection. I first tried connecting directly
to the mdb file using:
$conn = new COM("ADODB.Connection") or die ("Cannot create ADODB
Connection object.");
//$connstr =
"PROVIDER=MSDASQL;DBQ=/prices/mydb.mdb;"."DRIVER={Microsoft Access Driver
(*.mdb)};"
//$connstr = "Provider=Microsoft,.Jet.OLEDB.4.0; Data Source=".
realpath("prices/mydb.mdb") ." ;";
// I've never got the above two connection strings to work but I
include them for completeness and in case any realises they might help me!
$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=".
realpath("prices/mydb.mdb") ." ;";
$conn->open($connstr);
This worked on my localhost running IIS 5 (unsurprisingly) but fell over
immediately on the Linux box. I am told this is because COM support in PHP
before version 4.3.x is buggy (he PHP version installed on the server is
4.1.2). Is this true? Will upgrading to version 4.3.x solve all my
problems?
Also, I heard that converting the .mdb file to a .dbf file might help - but
how do I connect to that with PHP? The PHP manual says this about dbase
functions:
"These functions allow you to access records stored in dBase-format (dbf)
databases. There is no support for indexes or memo fields."
That's no good because I have long text fields in the Access database that
are of type "memo"!
The Manual also says "we recommend that you do not use dBase files as your
production database" - eek! It's only a small database (one table with
about 50 records, each with no more than 20 fields) so hopefully it will
suffice.
Am I right in thinking I have very few options? I don't want to move over
to ASP (would that even help?) because it means learning VBScript and I
don't have a lot of time. Also, I can't use another database (e.g. MySQL)
cos the server admin is NOT helping me and won't install anything new.
I know 99% of you will want to tell me to just back out of this horrible
tangle and take a different route, but is there one person out there who can
help me get through this nightmare?
Thank you!
