How to read a file content and convert it into an array

If you have a config.txt file containing the following code;

DB_HOST=localhost
DB_NAME=demo_database
DB_USER=root
DB_PASSWORD=dbpswd15

Please use the below function to read the text file content into an array with key and values;

/**
 * Function to read the file content and return into an array separating key = value;
 * @param $filepath The Document File path to read the file contents;
 * @return array Return the files content into array by separating each lines with '=' separated with first part as key (into lowercase) and second part key's as value.
 */
function get_file_content_in_array($filepath)
{
    $fp = fopen($filepath, "r") or die("Please configure the forum database.");

    $lines = array();

    while (!feof($fp))
    {
        $line = fgets($fp);

        //process line however you like
        $line = trim($line);

        // If line empty, do continue
        if (empty($line)) continue;

        // Split the line string with '=' operator into key and value;
        list($key, $value) = explode('=', $line);

        // check the empty key
        if (!empty($key)) {
            //add to array
            $lines[trim($key)] = trim($value);
        }
    }
    fclose($fp);

    return $lines;
}

To read the file content, just call the above below script after including the above function.

// Read the file and content and convert it into an array
$config = get_file_content_in_array($filepath = "cofig.txt");

Output:

Array
(
    [db_host] => localhost
    [db_name] => demo_database
    [db_user] => root
    [db_password] => dbpswd15
)

Xampp Apache and Visual Studio Port 80 conflict

If you already install Xampp Apache running into your PC and later install the Visual Studio 2015, then there will port conflicts. Normally, Visual Studio overtake the default IIS HTTP port 80 and use it.

However, if you want both to be working by running one at a time.

To do that,
Type Services.msc from the run command prompt > scroll down to World Wide Web Publishing service.
OR go to Control Panel > Administrative Tools > Services.msc > World Wide Web Publishing service.

Then, Right click  the Web Publishing and 'Stop' it, also, Go the same Properties and set a Startup type: 'Manual'.

Then, try to restart the apache. It should be working.

On the other hand, when you need to start the Visual Studio part of service, you can do same thing manually and later disable it.


Hope that helps;
