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'.
