PHP 8.4.0 RC2 available for testing

oci_fetch_assoc

(PHP 5, PHP 7, PHP 8, PECL OCI8 >= 1.1.0)

oci_fetch_assocReturns the next row from a query as an associative array

说明

oci_fetch_assoc(resource $statement): array|false

Returns an associative array containing the next result-set row of a query. Each array entry corresponds to a column of the row. This function is typically called in a loop until it returns false, indicating no more rows exist.

Calling oci_fetch_assoc() is identical to calling oci_fetch_array() with OCI_ASSOC + OCI_RETURN_NULLS.

参数

statement

有效的 OCI8 报表标识符 由 oci_parse() 创建,被 oci_execute()REF CURSOR statement 标识执行。

返回值

Returns an associative array. If there are no more rows in the statement then false is returned.

示例

示例 #1 oci_fetch_assoc() Example

<?php

$conn
= oci_connect('hr', 'welcome', 'localhost/XE');
if (!
$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

$stid = oci_parse($conn, 'SELECT department_id, department_name FROM departments');
oci_execute($stid);

while ((
$row = oci_fetch_assoc($stid)) != false) {
echo
$row['DEPARTMENT_ID'] . " " . $row['DEPARTMENT_NAME'] . "<br>\n";
}

oci_free_statement($stid);
oci_close($conn);

?>

Here's a simple example of using the oci_fetch_assoc function for anyone who would like to see it.

<?php
$oconn
= oci_connect('ora_user','ora_pass','ora_inst');
if (!
$oconn){
$msg = "Cannot connect to Oracle ".oci_error();
} else {
$msg = "Connected to Oracle";
}

$select_stmt = "select username from user_table";

$stid = oci_parse($oconn, $select_stmt);
oci_execute($stid);

echo
"<table border='1'>\n";

while (
$row = oci_fetch_assoc($stid)) {
echo
"<tr>\n";
echo
"<td>". $row["USERNAME"] . "</td>\n";
echo
"</tr>\n";
}

echo
"</table>\n";

oci_free_statement($stid);
oci_close($oconn);
?>

Make sure you capitalize the column name for referencing the item in the associative array. Of course, this is just a simple example and you might want to do some processing on the data prior to output, but you get the idea here.

Unlike oci_fetch_all(), after using oci_fetch_assoc(), LOB columns (CLOB, BLOB) are NOT returned as strings but as Oci-Lob objects. You have to use Oci-Lob->read() or load() method in order to read column content.
