# JOE syntax highlight file for PHP

# TODO:
#  * octal escape sequences
#  * heredoc support (as good as possible)
#  * highlight variables
#  * highlight function and class names?

# Define no. sync lines
# You can say:
# -200     means 200 lines
# -        means always start parsing from beginning of file when we lose sync
#          if nothing is specified, the default is -50

# Define colors
