note 15202 added to function.pg-fetch-array

I think it should be emphasized that the second group of fields (with the field names as keys) are associative arrays and so the array you get from pg_fetch_array wont behave like a normal array. $sql = "select foo,bar from mytable"; $arr = pg_fetch_array($result); echo $arr[0]; // ex: NT echo $arr[1]; // ex: 98 echo $arr[foo]; // ex: NT echo $arr[bar]; // ex: 98 but if I do: for ($i=0;$i<count($arr);$i++){ $arr[$i] = "linux"; } you might think all 4 fields would be overwritten, but with this type of array we get: echo $arr[0]; // ex: linux echo $arr[1]; // ex: linux echo $arr[3]; // ex: linux echo $arr[4]; // ex: linux and yet... echo $arr[foo]; // ex: NT echo $arr[bar]; // ex: 98 http://www.php.net/manual/en/function.pg-fetch-array.php
