Git commit commands

In my Git repo, I changed some files. I want to stage all of them. But is there a difference between commands:

git add file1.php file2.php

git add .

Does the second command stage only modified files, or all files from project? Or these commands are equal?

git add file1.php file2.php stages the files file1.php and file2.php.

git add . stages all files in the directory and all subdirectories, including uncommitted ones. (As long as they're not ignored by your .gitignore)

Either command will only stage a file if it's been modified, however.

If file1.php and file2.php are the only files that have changed or are untracked the two commands are equivalent, because unchanged files can't be staged anyway.

As explained by Sebastian P., these commands are not equavalent.

To stage all modified files, you can use git add -u

Also, for a quick commit of all modified files, you can use git commit -a which is equivalent to git add -u ; git commmit
