Nope, still doesn't work...for the moment I'll just preset the variables
and use double quotes for the query string. The actual insert statement
should be like this:
INSERT INTO gtest VALUES (city, GeomFromText('POINT(lon lat)', 4326))
where lon and lat are decimal numbers, and I wanted to replace city,
lon, lat with different values each time I insert...
It seems like any $var after a single quote, even with \', gets ignored?
I also tried using double quotes and escaping $, but doesn't work either..
Thanks though.

Hi,
I'm trying to set up a prepared sql statement with 3 parameters and
then execute with array of 3 elements (this is to a postgresql
database with postgis):
$result = pg_prepare($dbconn, "my_query", 'INSERT INTO gtest VALUES ($1,
GeomFromText(\'POINT($2 $3)\', 4326))');
$result = pg_execute($dbconn, "my_query", array("phptest", "23", "24"));
But when I ran it, it gave me this error:
Warning: pg_execute(): Query failed: ERROR: bind message supplies 3
parameters, but prepared statement "my_query" requires 1 in
/home/dlamoris/phptest.php on line 15
Probably because of the single quotes around the point() function.
Try the heredoc type syntax suggested on http://php.net/pg_prepare:
$my_query = <<<MYQRY
INSERT INTO gtest VALUES($1, GeomFromText('POINT('$2, $3')', 4326));
MYQRY;
Also I'd suggest naming the columns in the first part:
insert into gtest(col1, col2, col3) values (....);
so it's always in the same order and you're not relying on any
behaviour. If you add a column in the middle of your table later on,
this is going to break a lot of your code because the columns will be
out of order.
