Without this change it's not possible to override a file on FTP by calling Filesystem::copy($originFile, $targetFile, true) as PHP/FTP server responds with error like:

fopen(ftp://...@ftp/file.txt): failed to open stream: Remote file already exists and overwrite context option not specified FTP server reports 213 166440 []

TODO: Write an integration tests? How? Use some real FTP server?

This fix improves the constant-time algorithm used to compare strings, as it removes the `%` operator inside the loop.

[FrameworkBundle] PhpExtractor bugfix and improvements

PhpExtractor currently only handles simple strings which match an overly-specific token sequence.

This change adds support for
- heredoc / nowdoc
- inconsistent whitespace when parsing
- escaped sequences in strings
- `transChoice`
