使用magento

Question

我想用脚本更新我的local.xml。我想使用自定义脚本在xml中更改我的用户名，数据库名称和密码。我正在创建脚本。它可以显示节点的值并更新值但是它不能用节点中的值设置CDATA 代码： -

$xml = simplexml_load_file('app/etc/local.xml'); // connection details are inside of CDATA
$conn = $xml->global->resources->default_setup->connection;
echo $user =  $conn->username;
 $pass =  $conn->password;
 $pass =  $conn->dbname;
// create CDATA section

echo $conn->username = '<'.'![CDATA['.'user'.']]'.'>';
echo $conn->password = '<'.'![CDATA['.'pass'.']]'.'>';
echo $conn->dbname = '<'.'![CDATA['.'bdname'.']]'.'>';


$xml->asXML('app/etc/local.xml');

我想在xml中添加带有我的值的CDATA。像这样

<connection>
                    <host><![CDATA[localhost]]></host>
                    <username><![CDATA[root]]></username>
                    <password><![CDATA[ghrix321]]></password>
                    <dbname><![CDATA[bachatbay]]></dbname>
                    <initStatements><![CDATA[SET NAMES utf8]]></initStatements>
                    <model><![CDATA[mysql4]]></model>
                    <type><![CDATA[pdo_mysql]]></type>
                    <pdoType><![CDATA[]]></pdoType>
                    <active>1</active>
                </connection>

请建议我，我该怎么办？

Answer 1

尝试以下代码，并改变你想要的任何内容。

<?php
    $xmlFile = file_get_contents('Magen/app/etc/local.xml');// File you want to alter
    $xmlNodes = new SimpleXMLExtended($xmlFile);
    $xmlNodes->global->resources->default_setup->connection->dbname  = NULL;
    $domNode = dom_import_simplexml($xmlNodes->global->resources->default_setup->connection->dbname);
    $ownerNode   = $domNode->ownerDocument;
    $domNode->appendChild($ownerNode->createCDATASection('your_host_name')); //values you want to change
    $xmlNodes->asXML('Magen/app/etc/local.xml'); 
?>

注意：您可以通过迭代对象和数组来获取任何节点。

这是最终的代码。工作正常

$xmlFile = file_get_contents('app/etc/local.xml');
    $xmlNodes = new SimpleXMLElement($xmlFile);

    $xmlNodes->global->resources->default_setup->connection->dbname = NULL;
    $node = dom_import_simplexml($xmlNodes->global->resources->default_setup->connection->dbname);
    $no = $node->ownerDocument;
    $node->appendChild($no->createCDATASection($databasename));

    $xmlNodes->global->resources->default_setup->connection->username = NULL;
    $node = dom_import_simplexml($xmlNodes->global->resources->default_setup->connection->username);
    $no = $node->ownerDocument;
    $node->appendChild($no->createCDATASection($username));

    $xmlNodes->global->resources->default_setup->connection->password = NULL;
    $node = dom_import_simplexml($xmlNodes->global->resources->default_setup->connection->password);
    $no = $node->ownerDocument;
    $node->appendChild($no->createCDATASection($password));
    if($xmlNodes->asXML('app/etc/local.xml')){
        echo 'your local.xml is updated';   
    }else{
        echo 'Your local.xml is not updated';
    }
