how to pull out php code that contain certain words in ruby

问题

Say if i have lots of php file (.php) and I'm only want to pull out block of code that contain certain words e.g. $this->te Any idea how I do it? using ruby would be better?

if ($attachments && count($attachments) > 0) {
 echo "\n\n{$this->te('Attachments')}:\n";
 ...

回答1:

You can just use grep for it:

grep '$this->te' -R *.php -n

If you want to do similar thing with Ruby, you can use something like:

Dir.glob('*.php').each do |x|
  File.read(x).split("\n").each_with_index do |line, n|
    puts "Found at #{x}:#{n+1}" if line["$this->te"]
  end
end
