Make a script of button which gets value of UI.Toggle and stores it in a file

I'd be glad to help you, but you have to write your script by yourself if you want to learn anything.

For easily storing values, you can use PlayerPrefs.SetInt. To get the toggles' values, use Toggle.isOn. To get references to your toggles, the easiest way be would be to set them by drag and drop in the inspector, by either making them public or using the Serializefield attribute, like so :

 public class Save : MonoBehaviour
 {
     [SerializeField]
     Toggle JavaScriptToggle;
     [SerializeField]
     Toggle PHPToggle;
 
     // etc...
 }

Attach this script to your save button. Then in the editor, drag and drop your JavaScript toggle on the script's JavaScriptToggle field, etc. That way, in your script you can know if your toggle is on with JavaScriptToggle.isOn, and use PlayerPrefs.SetInt to save it (0 for false, 1 for true). Then when the game starts, you get all those saved values with PlayerPrefs.GetInt, and assign them to the toggles using Toggle.isOn again.

Finally, just set the save button's onClick event to call a function of your Save script, say, SaveToggles(), in which you will use PlayerPrefs to store all those values. In order to be able to call this function with the button's onClick, your method has to be public. So what you need is :

 public void SaveButtons()
 {
         PlayerPrefs.SetInt("JavaScript", JavaScriptToggle.isOn ? 1 : 0);
         // etc...
 }

In case you don't know what JavaScriptToggle.isOn ? 1 : 0 means, it is a ternary operator. It means : "if JavaScriptToggle is true, then return 1. Else return 0".

Try to understand all this, and you'll have no problem writing your script.
