PHP return the error:
Notice: Uninitialized string offset: 1 in show.php on line 4
How could I know the values of the text? without modify example.html
The easiest way would be to modify example.html and change each instance of
name=text to name=text[]. However, since you say you cannot do that, try
echoing $_SERVER['QUERY_STRING']. If that contains all 3 then you can parse
that to get the values out.
