Removing string characters form mysqli database and utilize two variables derived from database

hope this fix your issue You can first explode on the basis of "/" then you can substr(string,0,-1) to remove the last character from the string. After getting both upload speed and download speed you can convert them into Mb. I didn't convert it into Mb because you did not mention it is Kb or GB?
code :
$str = "10240k/10240k";
$str = explode("/",$str);
$UploadSpeed = substr($str[0], 0, -1);
$DownloadSpeed = substr($str[1], 0, -1);

To fix the issue you can do By default Codeigniter shopping cart class uses its built-in session functions. Session class in CI can be configured to use cookie or database, which means the shopping cart will EITHER use database or cookie to store session variables. , There are two methods possible.
code :
function product_insert() {   
  if(true) {
  } else {

This might help you Despite the fact that given the comments your code is insecure and you are ok with that, columns to be updated should not be separated by the AND operator in an UPDATE statement.
code :
UPDATE [LOW_PRIORITY] [IGNORE] table_reference
    SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
    [WHERE where_condition]

Kotlin-Firebase-cannot utilize the string read from database further down in the code

like below fixes the issue Data is loaded from Firebase asynchronously, as it may take some time before you get a response from the server. To prevent blocking the application (which would be a bad experience for your users), your main code continues to run while the data is being loaded. And then when the data is available, Firebase calls your onDataChange method.
What this means in practice is that any code that needs the data from the database, needs to be inside the onDataChange method or be called from there. So any code that requires selectedbrand needs to be inside onDataChange or called from there (typically through a callback interface).
