Обсуждение: pg_query undefined?

Does anyone know why trying to run a simple demo script (the one that came
with EZ_SQL from php.justinvincent.com) would be giving me an error saying
that pg_query() is an undefined function? It's a standard function built
into PHP, isn't it? It's listed in the manual...

I know the installation of PHP at our web host does have PostgreSQL support,
because when I ran phpinfo() it seemed to say all the right things about it,
so this is really confusing me.

Hi Lynna

> because when I ran phpinfo()
If you run phpinfo() you can see the PHP version.

pg_query() is supported since PHP 4.2.0

If your PHP is older than this use pg_exec() instead.

pg_query was new in PHP 4.2:

   http://us3.php.net/manual/en/function.pg-query.php
   "pg_query
    (PHP 4 >= 4.2.0)
    Note:  This function used to be called pg_exec(). pg_exec() is still
    available for compatibility reasons but users are encouraged to use
    the newer name."

What version does phpinfo say your host is running?

Also make sure that pgsql is installed in php. By checking the phpinfo()
function u can verify your php version (4.2+) and if pgsql has been
compiled into php.

If you have 4.2 or higher than u might need to compile pgsql into php.

Hi all,
best to use for simple statements is PEAR::DB. you can write code
abstract. i found this out while convert a DB from mysql to pgsql, now
we'll wrap table and field names. then we are always sureto write
universal code. the problem was the following:
mysql table and field names are sometimes uppercase
while converting with my2pg.pl all names changed to lowercase
alterante: quote tables and fields, but then quote it in your code to.
if you try to run this quoted code on mysql you'll get errors.
when we have all wrapped, i hope it will run under several RDBMS.
excuse my bad english, it's to long ago i learned it and not often spoken.
have fun, Gerd

Aha - that would be it! Thank you! I just checked phpinfo and it says it's
4.1.2.

I can do a global find and replace to turn all instances of pg_query into
pg_exec in the ez_sql script I downloaded, but now I wonder if there will be
other functions that have changed between versions as well. Guess the only
way to find out is to try.

*sigh* Yet another reason to loathe and despise the web host I'm stuck with
here. I could ask them to upgrade their PHP installation, but given that
they never answered my request to upgrade PostgreSQL a month ago (they're
still running 7.2), or my *four* requests (well, the same request sent four
times) for a working cgi-bin directory, or about 75% of any other tech
support requests I've sent them, I'm not holding out too much hope for this
one.

Can anyone recommend a *good* web host that supports PHP and PostgreSQL? One
that's affordable enough for a small non-profit art gallery?

Thanks,

Lynna

2.4.2 doesn't support 7.3, go get phppgadmin 3.0.

Thats not your problem, but you're not going to get too far until you
switch to 3.0.  Check your postgresql log for a FATAL message when you
try and connect, it should give a little better explanation of what went
wrong.

Subject: [PHP] phpPgAdmin 2.4.2

Installed postgreql 7.3.3 and phpPgAdmin 2.4.2 in different machines. Defined password for postgres superuser. Entry is created in the pg_shadow table for the same user. Keeping the access method in pg_hba.conf file as "trust", I do not have any problem. However when changed the access method to "password"  and tried managing the database using the phpPgAdmin tool I get

 

Error - /var/www/pgadmin.intranet/htdocs/lib.inc.php -- Line: 303

PostgreSQL said:
Your query:
Unable to connect with settings: host=host_name' port='post_num' dbname='template1' user='user_id' password='xxxxx'

 

The pg_hpa.conf file has an entry

"host    all         all         ip_address  ip_mask   password"

 

Any idea why this is happening.

Salah
