oci_fetch_array
(PHP 5, PECL oci8:1.1-1.2.4)
oci_fetch_array — Returns the next row from the result data as an associative or numeric array, or both
Opis
array oci_fetch_array
( resource $statement
[, int $mode
] )
Returns an array, which corresponds to the next result row.

It should be mentioned here, that oci_fetch_array() is insignificantly slower, than oci_fetch_row(), but much more handy.
Parametry
- statement
-
A valid OCI statement identifier.
- statement
-
An optional second parameter can be any combination of the following constants:
- OCI_BOTH - return an array with both associative and numeric indices (the same as OCI_ASSOC + OCI_NUM). This is the default behavior.
- OCI_ASSOC - return an associative array (as oci_fetch_assoc() works).
- OCI_NUM - return a numeric array, (as oci_fetch_row() works).
- OCI_RETURN_NULLS - create empty elements for the NULL fields.
- OCI_RETURN_LOBS - return the value of a LOB of the descriptor.
Zwracane wartości
Returns an array with both associative and numeric indices, or FALSE if there are no more rows in the statement .
Informacja: Ta funkcja ustala wartość pól NULL na NULL.
Informacja: Oracle returns all field names in uppercase and associative indices in the result array will be uppercased too.

As Robert Hicks mentioned back in August 2004 there is an error in examples 3 and 4 of this page. The error in example 3 is what dwhitaker and stry_cat address in their notes of 20 May 2005 and 9 June 2005 respectively.
The correct form of example 4 should read:
<?php
$connection = oci_connect("user", "password");
$query = "SELECT id, name, lob_field FROM fruits";
$statement = oci_parse ($connection, $query);
oci_execute ($statement);
while ($row = oci_fetch_array ($statement, OCI_RETURN_LOBS)) {
echo $row[0]."<br>";
echo $row[1]."<br>";
echo $row['LOB_FIELD']."<br>"; //this will output LOB's content
}
?>
This really should be corrected in the actual documentation...

If you want to get both nulls and an assoc array, you have to ADD the values like this:
$row = oci_fetch_array($stmt, OCI_RETURN_NULLS + OCI_ASSOC);
This really should be noted in the text of the manual.

OCI_BOTH is the default.
If you just need to return all fields, you can leave out OCI_NUM & OCI_ASSOC.
EXAMPLE:
<?php
$connection = ocilogon("user", "password", "dbname");
$query = "SELECT id, name, lob_field FROM fruits";
$statement = oci_parse ($connection, $query);
oci_execute ($statement);
while ($row = oci_fetch_array ($statement)) {
$id = $row['ID'];
$name = $row['NAME'];
$lob_field = $row['LOB_FIELD'];
echo $id.' '.$name.' '.$lob_field;
}
?>

Example 3 above is incorrect...
OCI_NUM should be OCI_ASSOC
So it should read something like this:
<?php
$connection = ocilogon("user", "password", "dbname");
$query = "SELECT id, name, lob_field FROM fruits";
$statement = oci_parse ($connection, $query);
oci_execute ($statement);
while ($row = oci_fetch_array ($statement, OCI_ASSOC)) {
$id = $row['ID'];
$name = $row['NAME'];
$lob_field = $row['LOB_FIELD'];
echo $id.' '.$name.' '.$lob_field;
}
?>

OCI_NUM should be changed in the various scripts to the appropriate call to the OCI_*. For example the script to show the OCI_ASSOC call still has OCI_NUMS in it.
