oci_fetch_array
(PHP 5, PECL oci8:1.1-1.2.3)
oci_fetch_array — 結果データからの次の行を連想配列または配列、またはその両方で返す
説明
array oci_fetch_array ( resource $statement [, int $mode] )次の結果行に相当する配列を返します。
oci8 ドライバによるデータ型マッピングの 詳細については、ドライバが サポートするデータ型 を参照ください。
ここで言っておくべき事は、oci_fetch_array() は oci_fetch_row() よりも 無意味に 遅い、ということですが、非常に使いやすい関数です。
パラメータ
- statement
有効な OCI ステートメント ID。
- statement
オプションの第2引数は、次の定数の組み合わせが可能です。
OCI_BOTH - 連想配列と配列の両方を返します (OCI_ASSOC + OCI_NUM と同等)。 これはデフォルトの動作です。 OCI_ASSOC - 連想配列を返します (oci_fetch_assoc() と同等)。 OCI_NUM - 配列を返します (oci_fetch_row() と同等)。 OCI_RETURN_NULLS - フィールドが NULL の場合、 空の要素を返します。 OCI_RETURN_LOBS - ディスクリプタの LOB の値を返します。 デフォルトの mode は OCI_BOTH です。
返り値
連想配列あるいは配列の両方を返します。 失敗時あるいは結果行がない場合は FALSE を返します。
注意: この関数は、 NULL フィールドに PHPの NULL 値を設定します。
注意: Oracle は全てのフィールド名を大文字で返し、 結果の連想配列のインデックスも大文字になります。

例 1594. OCI_BOTH を使った oci_fetch_array() の例
<?php
$connection = oci_connect("apelsin", "kanistra");
$query = "SELECT id, name FROM fruits";
$statement = oci_parse ($connection, $query);
oci_execute ($statement);
while ($row = oci_fetch_array ($statement, OCI_BOTH)) {
echo $row[0]." and ".$row['ID']." is the same<br>";
echo $row[1]." and ".$row['NAME']." is the same<br>";
}
?>
例 1595. OCI_NUM を使った oci_fetch_array() の例
<?php

oci_execute ($statement);
while ($row = oci_fetch_array ($statement, OCI_NUM)) {
echo $row[0]."<br>";
echo $row[1]."<br>";
echo $row[2]->read(100)."<br>"; //this will output first 100 bytes from LOB
}

oci_execute ($statement);
while ($row = oci_fetch_array ($statement, OCI_ASSOC)) {
echo $row['ID']."<br>";
echo $row['NAME']."<br>";
echo $row['LOB_FIELD']."<br>"; //this will output "Object id #1"
}
?>
例 1597. OCI_RETURN_LOBS を使った oci_fetch_array() の例
<?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_NUM+OCI_RETURN_LOBS))) {
echo $row[0]."<br>";
echo $row[1]."<br>";
echo $row['LOB_FIELD']."<br>"; //this will output LOB's content
}

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.
