pg_fetch_row is faster than pg_fetch_assoc when doing a query with * as the select parameter. Otherwise, with declared columns, the two are similar in speed.

Note, that when you retrieve some PG boolean value, you get 't' or 'f' characters which are not compatible with PHP bool.

I wondered whether array values of PostgreSQL are converted to PHP arrays by this functions. This is not the case, they are stored in the returned array as a string in the form "{value1 delimiter value2 delimiter value3}" (See http://www.postgresql.org/docs/8.0/interactive/arrays.html#AEN5389).

Get downlines, put them into arrays.

function get_downlines($my_code){

global $link;

$sql = "select user_id, name from tb_user where parentcode = $my_code";

$res = pg_query($link,$sql);

if(!$res){

echo "Error: ".$sql;exit();

}

$num_fields = pg_num_fields($res);

$info_rows = 0;

$num_rows = pg_num_rows($res);

while($arr = pg_fetch_row($res)){

$info_offset = 1;

$info_columns = 0;

while ($info_offset <= $num_fields) {

$info_elements[$info_rows][$info_columns] = $arr[$info_columns];

$info_offset++; $info_columns++;

}

$info_rows++;

}

return $info_elements;

}

Note that the internal row counter is incremented BEFORE the row is retrieved. This causes an off by one error if you try to do:

pg_result_seek($resid,0);

pg_fetch_row($resid);

you will get back the SECOND result not the FIRST.

I use the following code to assigning query result to an array.

while ($row = pg_fetch_row($result)) $newArray[] = $row[0];

print_r($newArray);

a way to do this with 2 loops to insert data into a table...

$num = pg_numrows($result);

$col_num = pg_numfields($result);

for ($i=0; $i

$line = pg_fetch_array($result, $i, PGSQL_ASSOC);

print "\t

\n";

for ($j=0; $j

list($col_name, $col_value) =each($line);

print "\t\t

$col_value\n";

}

echo "
";

}
