Обсуждение: Select count

Hi there!

I could not find in documentation, how I can get the result from a query
using select "count(*)". Today I use a "select * " and after using
pg_numrows and it woks but I want to know:Is there any other way to get this
result?

Thanks in advance.

$result = pg_exec($conn, "SELECT count(*) blah blah blah");
$count = pg_result($result, 0, 0);

That gets the first variable from the first row, fast.  If you're using
fetcharray, you can also use the name 'count' I think, or if that
doesn't work, label it with "SELECT count(*) as foo" and ask for foo.
