pg_fetch_rowCarica una tupla in un array


array pg_fetch_row ( resource $result , int $tupla )

pg_fetch_row() carica un record dal risultato della query associato alla risorsa identificata da result. La riga (record) è restituia sotto form di array. Ogni campo è identificato da un indice numerico, che inizia da 0.

Restituisce un array che corrisponde alla riga caricata, oppure FALSE se non ci sono altre tuple.

Example #1 Postgres fetch row

pg_pconnect ("dbname=editori");
if (!
$conn) {
"Si è verificato un errore.\n";

$result pg_query ($conn"SELECT * FROM autori");
if (!
$rrisultato) {
"Si è verificato un errore.\n";

while (
$row pg_fetch_row($risultato$i)) {
  for (
$j=0$j count($row); $j++) {



Vedere anche pg_query(), pg_fetch_array(), pg_fetch_object() e pg_fetch_result().


Dalla versione 4.1.0, row è opzionale. La chiamata a pg_fetch_row() incrementa il puntatore alle tuple di 1.

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

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.

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

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>";

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:


you will get back the SECOND result not the FIRST.

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,$sql);
        echo "Error: ".$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++;
return $info_elements;

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

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