连接 php 和 oracle 11gr2 express

Question

我一直在开发一个需要 oracle 数据库和 php 的新项目，我使用 Xampp 我已经下载并安装了所有必要的配置，但我收到以下错误无论我在网上找到并尝试了多少解决方案，都被证明是忙碌的，我该如何解决这个问题

Warning: oci_connect(): ORA-12514: TNS:listener does not currently know of service requested in connect descriptor in C:\xampp\htdocs\Dos\index.php on line 3

Warning: oci_parse() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\Dos\index.php on line 6

Warning: oci_error() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\Dos\index.php on line 8

Fatal error: in C:\xampp\htdocs\Dos\index.php on line 9

我的连接代码

<?php

$conn = oci_connect('blue','password','localhost/XE');

// Prepare the statement
$stid = oci_parse($conn, 'SELECT * FROM  persons');
if (!$stid) {
    $e = oci_error($conn);
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

// Perform the logic of the query
$r = oci_execute($stid);
if (!$r) {
    $e = oci_error($stid);
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

// Fetch the results of the query
print "<table border='1'>\n";
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
    print "<tr>\n";
    foreach ($row as $item) {
        print "    <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : "&nbsp;") . "</td>\n";
    }
    print "</tr>\n";
}
print "</table>\n";

我是 oracle 的新手，请帮助我解决这个问题..谢谢

Answer 1

您在 tnsnames.ora 中的数据库名称是 XE，而不是 localhost/XE，这意味着您的连接线可能是；

$conn = oci_connect('blue','password','XE');

此外，在 tnsnames.ora 中，数据库的主机设置为 JACKSOM.COM 并且可能应该是 127.0.0.1 以连接到本地主机上的 XE，即；

XE =
 (DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1522))
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = XE)
   )
 )
