How write arrays name while parsing an ini file in PHP? - php

Question

I am using parse_ini_file to parse an ini file using PHP.
Now I first upload an INI file to my server then open it and allow user to mak custom changes to the file.
Now once users has edited the file i get the data from post and save the file back to server. But Now i dont get my sections. INIdetails,Dialplan in the updated file so when i also want to write that to file how to do that?
This is the code :
$this->data['parameters'] = parse_ini_file($path.$filename,true);
/*Getting Our POST DATA from View*/
$data = 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'),
'Param_1' => $this->input->post('Param_1'),
'Param_2' => $this->input->post('Param_2')
);
/*Creating New file with the name of customer loggedin*/
$name = $this->session->userdata('username');
$ext = $this->session->userdata('extension');
$custom_file = fopen('uploads/'.$name.'_'.$ext.'.ini', 'w');
fwrite($custom_file, "[INIDetails]\n");
foreach ($data as $key => $value)
{
fwrite($custom_file, " $key = $value\n");
}
fclose($custom_file);
/*Setting path to New CUSTOM file with customer name as prefix*/
$file = $path.$custom_file;
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($fp);
}
}
/*Creates ini file, dumps array to string and creates .INI file*/
write_php_ini($data,$file);

Answer 1

The culprit from your previous code is that your array is not formatted correctly, it should be array of arrays to achieve what you want.
Try below code:
// First read the ini file that the user was editing
// Your idea to read the existing ini file is good, since it will generate you the structured array
$previous_data = parse_ini_file($path . $filename, true);
// Overwrite/edit the previous_data using user's post data
$previous_data['INIDetails']['SipUserName'] = $this->input->post('SipUserName');
$previous_data['INIDetails']['Password'] = $this->input->post('Password');
$previous_data['INIDetails']['Domain'] = $this->input->post('Domain');
$previous_data['INIDetails']['Proxy'] = $this->input->post('Proxy');
$previous_data['INIDetails']['Port'] = $this->input->post('Port');
$previous_data['INIDetails']['SipAuthName'] = $this->input->post('SipAuthName');
$previous_data['INIDetails']['DisplayName'] = $this->input->post('DisplayName');
$previous_data['INIDetails']['ServerMode'] = $this->input->post('ServerMode');
$previous_data['INIDetails']['UCServer'] = $this->input->post('UCServer');
$previous_data['INIDetails']['UCUserName'] = $this->input->post('UCUserName');
$previous_data['INIDetails']['UCPassword'] = $this->input->post('UCPassword');
$previous_data['DialPlan']['DP_Exception'] = $this->input->post('DP_Exception');
$previous_data['DialPlan']['DP_Rule1'] = $this->input->post('DP_Rule1');
$previous_data['DialPlan']['DP_Rule2'] = $this->input->post('DP_Rule2');
$previous_data['DialPlan']['OperationMode'] = $this->input->post('OperationMode');
$previous_data['DialPlan']['MutePkey'] = $this->input->post('MutePkey');
$previous_data['DialPlan']['Codec'] = $this->input->post('Codec');
$previous_data['DialPlan']['PTime'] = $this->input->post('PTime');
$previous_data['DialPlan']['AudioMode'] = $this->input->post('AudioMode');
$previous_data['DialPlan']['SoftwareAEC'] = $this->input->post('SoftwareAEC');
$previous_data['DialPlan']['EchoTailLength'] = $this->input->post('EchoTailLength');
$previous_data['DialPlan']['PlaybackBuffer'] = $this->input->post('PlaybackBuffer');
$previous_data['DialPlan']['CaptureBuffer'] = $this->input->post('CaptureBuffer');
$previous_data['DialPlan']['JBPrefetchDelay'] = $this->input->post('JBPrefetchDelay');
$previous_data['DialPlan']['JBMaxDelay'] = $this->input->post('JBMaxDelay');
$previous_data['DialPlan']['SipToS'] = $this->input->post('SipToS');
$previous_data['DialPlan']['RTPToS'] = $this->input->post('RTPToS');
$previous_data['DialPlan']['LogLevel'] = $this->input->post('LogLevel');
// Set Name of New file with the name of customer logged in
$name = $this->session->userdata('username');
$ext = $this->session->userdata('extension');
$custom_file = "$name_$ext.ini";
$new_filename = $path . $custom_file;
// Write the INI file
write_php_ini($data, $new_filename);
function write_php_ini($array, $new_filename)
{
$res = array();
foreach ($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 : '"' . $val . '"');
}
}
safefilerewrite($new_filename, implode("\r\n", $res));
}
function safefilerewrite($new_filename, $dataToSave)
{
if ($fp = fopen($new_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);
}
}
From your previous code, there are bunch of inappropriate codes which I remove. Also, too many inconsistencies like Method naming, variable naming etc.
If your function was named Camel cased then through out your code it must be named as camel-cased. If your variables are with underscore, then through out your code, they must have underscore for two or more worded variable.
I didn't edit the naming convention of your code so you won't be confused but i suggest to have a consistent naming convention through out your project.
UPDATED:
based on your answer, it seems like you changed your whole code. I would like to provide another way using nested foreach and passing by reference that save couple of lines:
$this->data['params'] = $this->parameter_m->get();
$this->data['parameters'] = parse_ini_file($path . $filename, true);
foreach ($this->data['parameters'] as $key_header => &$value_header) {
foreach ($value_header as $key_item => &$value_item) {
$value_item = $this->input->post($key_item);
}
}
$this->load->helper('file');
$this->load->library('ini');
$file = $path . $filename;
$ini = new INI($file);
$ini->read($file);
$ini->write($file, $this->data['parameters']);

Answer 2

Finally i got an answer:
I will loop through what i get from POST and will get each array's key. And then i will give the resultant to my Write Method
$this->data['params'] = $this->parameter_m->get();
/*Getting the parameters to display on view*/
$this->data['parameters'] = parse_ini_file($path.$filename,true);
while (current($this->data['parameters']) )
{
$param_set = current($this->data['parameters']);
$param_type = key($this->data['parameters']);
foreach ($param_set as $key =>$value)
{
$this->data['parameters'][$param_type][$key] = $this->input->post($key);
}
next($this->data['parameters']);
}
$this->load->helper('file');
$this->load->library('ini');
$file = $path.$filename;
$ini = new INI($file);
$ini->read($file);
$ini->write($file, $this->data['parameters']);
