Shell命令用于计算文件中的单词

Question

I want to run a command, that will count the number of words in all file. (From the selected number of files)

If i do like, find ABG-Development/ -name "*.php" | grep "<?" | wc -l find ABG-Development/ -name "*.php" | grep "<?" | wc -l find ABG-Development/ -name "*.php" | grep "<?" | wc -l , it will search only in the filename not the file contents.

And I tried one more way like

find ABG-Development/ -name "*.php" -exec grep "<?" {} \\; | wc -l find ABG-Development/ -name "*.php" -exec grep "<?" {} \\; | wc -l , I got error.

In above example I need how many time "

Please help..
