oci_fetch_array

(PHP 5, PECL oci8 >= 1.1.0)

说明

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.

参数

statement

A valid OCI statement identifier.

mode

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.

返回值

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

Note: 本函数对 PHP NULL 值设定 NULL 字段。

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

范例

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
}
?>
