用Eclipse PDT开发PHP时，Eclipse会自动创建几个系统文件。这些文件在Git提交时可以忽略。
使用git status可以看到这些文件(.project, .buildpath和.settings)：
$ git status # On branch master # Untracked files: # (use "git add <file>..." to include in what will be committed) # # .buildpath # .project # .settings/ # includes/ # index.php nothing added to commit but untracked files present (use "git add" to track)
怎么忽略呢？方法是创建.gitignore文件，将需要略过的文件名和目录名添加到.gitignore：
$ cat .gitignore .project .buildpath .settings
再用git status查看，就看不到这几个文件了：
$ git status # On branch master # Untracked files: # (use "git add <file>..." to include in what will be committed) # # .gitignore # includes/ # index.php nothing added to commit but untracked files present (use "git add" to track)
