PHP Encoder

bencoder is a script to automate the encoding task using bcompiler.

bcompiler has the capability to encode entire script in a proprietary PHP application.

But the encoding task needs to be done manually, by calling the functions provided by bcompiler,
such as bcompiler_write_header(), bcompiler_write_file() and bcompiler_write_footer() functions.

bencoder can do these for you, it’s very similar to the encoder script provided by eAccelerator.

bencoder is an open source software. It applies GPL license.

Usage

bencoder [-f] [-q] [-t] -o FILE    file1.php
bencoder [-f] [-q] [-t] -o OUTDIR  file1.php file2.php ...
bencoder [-f] [-q] [-t] -o OUTDIR  -s SRCDIR  [-e SUFFIX] [-r] [-c] [-l]

  -o FILE   : the file name to write the encoded script
              (default to '-encoded.XXX' suffix)
  -o OUTDIR : the directory to write all encoded files

  -s SRCDIR
  -a SRCDIR : encode all files from this source directory

  -r        : encode directories recursively (no by default)
  -f        : force overwriting even if the target exists
  -t        : truncate/keep only the basename of the file into the bytecode
  -e SUFFIX : encode the files with the SUFFIX extension only (default: php)
              (regular expression allowed, ex: "php|inc")
  -c        : copy files those shouldn't be encoded (no by default)
  -l        : follow symbolic link (no by default)
  -q        : do not print the file name while encoding or copying
  -b
  -bz2      : compress the encoded files with bz2 (needs bzip2-extension)
