how to trim a string into two Integers and one string (php)? -


I have a query variable example "4X9"

How can I do this in 3 different variables Can I divide an integer 4, integer 9 and string x?

I tried to use 

  $ arr = explosion ('x', $ question); $ First = $ arr [0]; $ Bbefore = str_replace ('' ',' ', $ first); $ newBefore = (int) $ first; `  
 and for later.  
 
 
  list ($ first, $ x, after $) = str_split (str_replace ('' ',' ', $ question));   
 1) Explain the string using the character - 2) Use them to illustrate them. 3) If you can add integers after this line of code after  $ before  and / or  $   
  list ($ $, $ X, $ after) = str_split (str_replace ('' ',' ', $ question)); $ = (int) $ first, $ = = (int) after $;
