How to parse and write .ini file in codeigniter PHP? - php

Question

I am uploading a INI file in Codeigniter.
I file upload a file with some parameters but its values are blank, and i store the file and file-path in database.
Now, I want to let user write some values to that file.
So i open the file and let user add some values to it.
But when i save the file its doesn't get stored the way i want.
Current Result
SipUserName = ""
SipAuthName = ""
DisplayName = ""
Password = ""
Domain = ""
Proxy = ""
Port = ""
ServerMode = ""
UCServer = 123456
UCPassword = 123456
DP_Exception = 123456
DP_Rule1 = 123456
DP_Rule2 = 123456
OperationMode = 123456
MutePkey = 123456
Codec = 123456
PTime = 123456
AudioMode = 123456
SoftwareAEC = 123456
EchoTailLength = 123456
PlaybackBuffer = 123456
CaptureBuffer = 123456
JBPrefetchDelay = 123456
JBMaxDelay = 123456
SipToS = ""
RTPToS = 123456
LogLevel = 123456
Expected Result:
[INIDetails]
SipUserName =
SipAuthName =
DisplayName =
Password =
Domain =
Proxy =
Port =
ServerMode =
UCServer = 123456
UCPassword = 123456
[DialPlan]
DP_Exception = 123456
DP_Rule1 = 123456
DP_Rule2 = 123456

Below is my code:
public function edit_ini($id)
{
/*The ID wen get from View's URI*/
$path = "./uploads/";
$site = $this->session->userdata('site');
/*Set the path to open the file*/
$this->db->select('*');
$this->db->where('site_key',$site);
$this->db->where('id',$id);
/*Here the id it the ID we got in URI from View*/
$this->db->from('base_ini');
$query = $this->db->get();
$result = $query->row();
$filename= $result->base_ini_filename;
$path= $result->file_path;
echo $this->db->last_query();
/*Setting the Path and the filename from database.*/
file_get_contents($path.$filename);
/*Get All The Contents from that file*/
$this->data['params'] = $this->parameter_m->get();
/*Getting the parameters to display on view*/
$this->data['parameters'] = parse_ini_file($path.$filename,true);
$insert = array(

function write_php_ini($array, $file)
{
$res = array();
foreach($array as $key => $val)
{
if(is_array($val))
{
$res[] = "[$key]";
foreach($val as $skey => $sval) $res[] = "$skey = ".(is_numeric($sval) ? $sval : '"'.$sval.'"');
}
else $res[] = "$key = ".(is_numeric($val) ? $val : '"'.$val.'"');
}
safefilerewrite($file, implode("\r\n", $res));
}
function safefilerewrite($fileName, $dataToSave)
{ if ($fp = fopen($fileName, 'w'))
{
$startTime = microtime(TRUE);
do
{ $canWrite = flock($fp, LOCK_EX);
// If lock not obtained sleep for 0 - 100 milliseconds, to avoid collision and CPU load
if(!$canWrite) usleep(round(rand(0, 100)*1000));
} while ((!$canWrite)and((microtime(TRUE)-$startTime) < 5));
//file was locked so now we can store information
if ($canWrite)
{ fwrite($fp, $dataToSave);
flock($fp, LOCK_UN);
}
fclose($fp);
}
}
/*Inserting The Data into .ini File*/
write_php_ini($insert,$file);
/*Back to you index page id data is submmited*/
if(isset($_POST['submit'] ))
{
redirect('customer/upload_ini/index');
}
$this->data['subview'] = 'customer/upload/edit_ini';
$this->load->view('customer/_layout_main', $this->data);
}
I want to print the sections into file.

This is not a complete solution, but some corrections to do to your code
First thing : please avoid the ternary operator, your code must always be as clear as possible, also you haven't planned the case where your value is null/empty
please try as follow
foreach($val as $skey => $sval) {
$configPrefix = $skey . ' = ';
if (!is_null($sval) && !empty($sval)) {
if (is_numeric($sval)) {
$res[] = $configPrefix . $sval;
}
else if (is_string($sval)) {
$res[] = $configPrefix . "'" .
$sval . "'" ;
}
else {
// TODO Log/throw exception for your unhandled case ...
}
}
}
Also you didn't decomposed your $insert array by sections, so use this and adapt your code to write sections in your ini file
$insert = array(
'INIDetails' => array(
'SipUserName' => $this->input->post('SipUserName'),
'SipAuthName' => $this->input->post('SipAuthName'),
'DisplayName' => $this->input->post('DisplayName'),
'Password' => $this->input->post('Password'),
'Domain' => $this->input->post('Domain'),
'Proxy' => $this->input->post('Proxy'),
'Port' => $this->input->post('Port'),
'ServerMode' => $this->input->post('ServerMode'),
'UCServer' => $this->input->post('UCServer'),
'UCPassword' => $this->input->post('UCPassword')
),
'DialPlan' => array(
'DP_Exception' => $this->input->post('DP_Exception'),
'DP_Rule1' => $this->input->post('DP_Rule1'),
'DP_Rule2' => $this->input->post('DP_Rule2')
),
'Advanced' => array(
'OperationMode' => $this->input->post('OperationMode'),
'MutePkey' => $this->input->post('MutePkey'),
'Codec' => $this->input->post('Codec'),
'PTime' => $this->input->post('PTime'),
'AudioMode' => $this->input->post('AudioMode'),
'SoftwareAEC' => $this->input->post('SoftwareAEC'),
'EchoTailLength' => $this->input->post('EchoTailLength'),
'PlaybackBuffer' => $this->input->post('PlaybackBuffer'),
'CaptureBuffer' => $this->input->post('CaptureBuffer'),
'JBPrefetchDelay' => $this->input->post('JBPrefetchDelay'),
'JBMaxDelay' => $this->input->post('JBMaxDelay'),
'SipToS' => $this->input->post('SipToS'),
'RTPToS' => $this->input->post('RTPToS'),
'LogLevel' => $this->input->post('LogLevel')
)
);

Answer 2

parse_ini_file(), and work on the associative array.
sample:
$ini_array = parse_ini_file("sample.ini", true);
print_r($ini_array);
you have to pass true as second argument to get correct format.
