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

Description

array oci_fetch_array ( resource $statement [, int $mode ] )

Returns an array, which corresponds to the next result row.

For details on the data type mapping performed by the oci8 driver, see the datatypes supported by the driver

It should be mentioned here, that oci_fetch_array() is insignificantly slower, than oci_fetch_row(), but much more handy.

Parameters

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.

Default mode is OCI_BOTH.

Return Values

Returns an array with both associative and numeric indices, or FALSE if there are no more rows in the statement .

Note: This function sets NULL fields to the PHP NULL value.

Note: Oracle returns all field names in uppercase and associative indices in the result array will be uppercased too.

Examples

Example #1 oci_fetch_array() with OCI_BOTH example

<?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>";
}
?>

Example #2 oci_fetch_array() with OCI_NUM example

<?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)) {
    echo $row[0]."<br>";
    echo $row[1]."<br>";
    echo $row[2]->read(100)."<br>";  //this will output first 100 bytes from LOB
}
?>

Example #3 oci_fetch_array() with OCI_ASSOC example

<?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_ASSOC)) {
    echo $row['ID']."<br>";
    echo $row['NAME']."<br>";
    echo $row['LOB_FIELD']."<br>";  //this will output "Object id #1"
}
?>

Example #4 oci_fetch_array() with OCI_RETURN_LOBS example

<?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
}
?>
