if (!
$conn) {
 echo
"An error occured.\n";
 exit;
}

$result = pg_query($conn, "SELECT * FROM authors");

}

$arr = pg_fetch_all($result);

var_dump($arr);

?>

This function returns NULL if the parameter is false.

pg_fetch_all, despite the app note, accepts only one argument, the resultset. It does exactly what is expected, returning a two-dimensional array of the resultset. I suspect the app note given was just copied from pg_fetch_array, which is what you want to use for a single row.

It seems like pg_fetch_all() only works on version 4.3.x. I tried it with 4.2.2 and it does not recognize the function, so I assume it won't work on 4 => 4.2.x.

I'm using PHP 5.0.1 and pg_fetch_all and here pg_fetch_all is also not recognized as function

php dot net

For versions of PHP that don't yet support the new names or newer functions I wrote a couple functions like this one
if (! function_exists("pg_fetch_all")) {
 function pg_fetch_all($res, $kind="assoc") {
   $i = 0; // this is needed for the row integer in the looped pg_fetch_array
   if ($kind == "assoc") {
     while ($row = pg_fetch_array($res, $i, PGSQL_ASSOC)) {
       $array_out[] = $row;
       $i++;
   }else{
     while ($row = pg_fetch_array($res)) {
       $array_out[] = $row;
     }
   }
   return $array_out;
 }
}

Also for those who are trying to move off oracle, pg_fetch_all returns an array with rows and columns inverted in the sense of ocifetchall. You would need to transpose this result array before your code takes the first index a column name and the second index a row index.
