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; $i<$num; $i++) {

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

  print "\t<tr bgcolor=#dddddd>\n";

    for ($j=0; $j<$col_num; $j++){

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

    print "\t\t<TD ALIGN=RIGHT><FONT SIZE=1 FACE='Geneva'>$col_value</FONT></TD>\n";

    }

  echo "<br>";

  }

the mysql way....



$rows = pg_numrows($result);

for ($i=0; $i < $rows; $i++){

    list($foo,$bar) = pg_fetch_row($result,$i);



    print ("$foo , $bar)\n");

}
