What I need Is to go thru a directory that contains subdirectories. In each second level directory has a third level directory that contains a file with same file name for every second level directory.

In each of those files made in PHP there Is a variable that contains like: appversion = 'YYYYMMDD'. I need to modify this date for each appearance To eg appversion = '20190301'.

How to do this In Shell or with PHP?

Edit: sorry for the malformed question, this is what defines better what I need to do really

I am afraid the question was a little malformed.
What I need to do is:
1. To find in all subdirectories a file called "productver.php".
2. In each "productver.php" file find a variable called 'appversion'.
3. Replace the value with a given value that i provide.
Example: I provide a date that is "20190324" and I want to change this to the value of all 'appversion' variables. E.g. 'appversion = 20180121' ==> 'appversion = 20190324'. For this reason, I am afraid simple replace is not enough as I only need to replace the part which is on the right side of the "=" character. And I cannot seek for a specific date, because the dates of this variable change. All I know is that I need to replace those dates, on the right side of the "=" sign of variable 'appversion'.

  is it a one time issue or you need an automation? This can be done using IDE (Search and Replace or Refactor..). Otherwise a shell script using sed would be perfect.

  PHP str_replace('YYYYMMDD', '20190301', $string), sed could be used in shell.
