如何在 CodeIgniter 中编辑上传的文件

我正在使用CodeIgniter上传一个.ini文件。

上传文件后，我使用 PHP 的 INI 解析器并将文件内容作为数组获取。

现在我想编辑该文件的内容。我该怎么做？

我的代码：

function do_upload()
{
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = '*';
    $this->load->library('upload', $config);
    $this->upload->initialize($config);
    if ( ! $this->upload->do_upload())
    {
        $error = array('error' => $this->upload->display_errors());
        $this->load->view('customer/upload/upload_ini', $error);
    }
    else
    {
        $data = array('upload_data' => $this->upload->data());
        foreach ($data as $info)
        {
            $filepath = $info['file_path'];
            $filename= $info['file_name'];
        }
        $this->data['parameters'] = parse_ini_file($filepath.$filename);
        $this->data['subview'] = 'customer/upload/upload_success';
        $this->load->view('customer/_layout_main', $this->data);
    }
}

在观点中，我做到：

<?php 
var_dump($parameters);
?>
<tr>
    <td>OTAID</td>
    <td><?php echo form_input('OTAID', set_value('OTAID', $parameters->OTAID)); ?></td>
</tr>
<tr>
    <td>SipUserName</td>
    <td><?php echo form_input('SipUserName', set_value('SipUserName', $parameters->SipUserName)); ?></td>
</tr>
<tr>
    <td>SipAuthName</td>
    <td><?php echo form_input('email2', set_value('email2', $parameters->email2)); ?></td>
</tr>
<tr>
    <td>DisplayName</td>
    <td><?php echo form_input('email2', set_value('email2', $parameters->email2)); ?></td>
</tr>
<tr>
    <td>Password</td>
    <td><?php echo form_input('email2', set_value('email2', $parameters->email2)); ?></td>
</tr>
<tr>
    <td>Password</td>
    <td><?php echo form_input('email2', set_value('email2', $parameters->email2)); ?></td>
</tr>
<tr>
    <td>Domain</td>
    <td><?php echo form_input('email2', set_value('email2', $parameters->email2)); ?></td>
</tr>
<tr>
    <td>Proxy</td>
    <td><?php echo form_input('email2', set_value('email2', $parameters->email2)); ?></td>
</tr>
<tr>
    <td>ServerMode</td>
    <td><?php echo form_input('email2', set_value('email2', $parameters->email2)); ?></td>
</tr>

从我的文件中，我得到了以下内容：

array (size=9)
    'OTAD' => string '0' (length=1)
    'PName' => string '' (length=0)
    'UName' => string '' (length=0)
    'DisplayName' => string '' (length=0)
    'Password' => string '' (length=0)
    'Domain' => string '' (length=0)
    'Proxy' => string '' (length=0)
    'Port' => string '' (length=0)
    'ServerMode' => string 'Automatic' (length=9)
