update config.php with variables

I have this php setup of writing a config file directly and i would like to update the variable in the file instead of writing the whole file. Can anyone point me in the right direction?

  $allowedExts = array(".jpg", ".jpeg", ".gif", ".png");
  $extension = strrchr ($_FILES["logoFile"]['name'], '.');

  if (($_FILES["logoFile"]["size"] < 2000000)
  && in_array($extension, $allowedExts))
  {
if ($_FILES["logoFile"]["error"] > 0)
{
    echo "Return Code: " . $_FILES["logoFile"]["error"] . "<br />";
}
else
{

move_uploaded_file($_FILES["logoFile"]["tmp_name"],"../../upload/logo".$extension);



$path= "./upload/logo".$extension;

//update logo settings variable

$data = file_get_contents('../settings/settings.php'); // grab data
$data = str_replace("/'LOGO_IMAGE_PATH', '[^']+'/", "'LOGO_IMAGE_PATH', '$path'", $data); // replace that section
file_put_contents('../settings/settings.php', $data); // save data


}
}
else
{
    echo "Invalid file";
}

And the rest of the variables are from the saveSettings.

case "saveSettings":

        //Logo settings
        $showLogo=$_REQUEST["showLogoOption"];
        $roundOption=$_REQUEST["roundOption"];
        $siteTitle=$_REQUEST["siteTitle"];
        $requireJobTypes=$_REQUEST["requireJobTypes"];
        $enableJobTypes=$_REQUEST["useJobTypes"];
        $enableMileage=$_REQUEST["enableMileage"];
        $allowViewingPayrolls=$_REQUEST["allowViewingPayrolls"];
        $trackIP=$_REQUEST["trackIP"];
        $enableMobile=$_REQUEST["enableMobile"];
        $config="<?php 
           define('USE_LOGO_IMAGE', $showLogo);
           define('ROUND_TO_QUARTERS', $roundOption);
           define('SITE_TITLE', '$siteTitle');
           define('ENABLE_JOB_TYPES', $enableJobTypes);
           define('REQUIRE_JOB_TYPES', $requireJobTypes);
           define('ENABLE_MILEAGE', $enableMileage);
           define('ALLOW_VIEW_PAYROLLS', $allowViewingPayrolls);
           define('TRACK_IP', $trackIP);
           define('MOBILE_VERSION_ENABLED', $enableMobile);
        ?>";
        $fp = fopen("../settings/settings.php", "w");
        fwrite($fp, $config);
        fclose($fp);
        break;

Thank you.

This is the function that will update settings for you, it will do it so your settings.php file is only modified once during the setup process so it won't needlessly open the file for every setting. It will save them all in one swoop.

function save_settings($settings) // function to update settings to file
{
    $data = file('../settings/settings.php', FILE_SKIP_EMPTY_LINES); // grab current settings file

    foreach ($data as $key => $line) // loop through lines in file
    {
        foreach ($settings as $name => $value) // loop through settings that are being modified
        {
            if (strcasecmp('true', $value) && strcasecmp('false', $value)
            && '0' !== $value && '1' !== $value)
            {
                $value = "'" . htmlspecialchars($value, ENT_QUOTES) . "'"; // quote non-boolean, also escape quotes
            }

            if (FALSE !== strpos($line, $name)) // if exists update it
            {
                $data[$key] = "define('" . $name . "', " . $value . ");\n"; 
            }
        }
    }
    file_put_contents('../settings/settings.php', implode('', $data)); // save it all
}

Put this line at the beginning of our setup process

// run this line BEFORE you begin to set values in settings.php to initialize the settings array
$settings = array();

You then modify settings like so:

// update settings easily by doing the below anywhere you like
// as long as it is after the above line and before you run save_settings()
$settings['LOGO_IMAGE_PATH']        = $path;
$settings['USE_LOGO_IMAGE']         = $_POST['showLogoOption'];
$settings['ROUND_TO_QUARTERS']      = $_POST['roundOption'];
$settings['SITE_TITLE']             = $_POST['siteTitle'];
$settings['ENABLE_JOB_TYPES']       = $_POST['requireJobTypes'];
$settings['REQUIRE_JOB_TYPES']      = $_POST['useJobTypes'];
$settings['ENABLE_MILEAGE']         = $_POST['enableMileage'];
$settings['ALLOW_VIEW_PAYROLLS']    = $_POST['allowViewingPayrolls'];
$settings['TRACK_IP']               = $_POST['trackIP'];
$settings['MOBILE_VERSION_ENABLED'] = $_POST['enableMobile'];

Then when you are all done you finalize the settings file by saving it with the updated settings:

// run this line at the end to save ALL settings AFTER you are done setting their values
save_settings($settings);

you can do something like this.

// Pass the array to update

function update_config($myConfig) {
  $myConfig = json_encode($myConfig);
  $fp = fopen('my_config.ini', 'a');
  fwrite($fp, $myConfig);
  return 'success';
}

// update config when you need

$myConfig = array();
$myConfig['section_1'] = "a";
$myConfig['section_2'] = "b";
$myConfig['section_3'] = "c";
echo update_config($myConfig)
