Using PostgreSQL 7.2 and PHP 4.1.2 in Linux, I found that some code is
becoming similar with the MySQL+PHP. For instance, you don't need to know the
numrows first to do a loop that display a query result.
New PostgreSQL+PHP way:
while($display=pg_fetch_array($getquery))
{
...
}
MySQL way :
while($display=mysql_fetch_array($getquery))
{
...
}
You can also use pg_numrows() instead of pg_num_rows() and some other 'new'
syntax that are like mysql way.
