" Vim syntax file
" Language:     PHP 4/5
" Maintainer:   Peter Hodge <toomuchphp-vim@yahoo.com>
" Last Change:  May 7, 2008
"
" URL:      http://www.vim.org/scripts/script.php?script_id=1571
" Version:  0.9.7
"
" ================================================================
"
" Note: If you are having speed issues loading or editting PHP files, try
"       disabling some of the options.  In your .vimrc, try adding:
"         :let php_folding = 0
"         :let php_strict_blocks = 0
"
"       Also, there is a 'large file' mode which can disable certain options
"       if a PHP file is too big (see php_large_file below).
"
" ================================================================
"
" Note: If you are using a colour terminal with a dark background, you will
"       probably find the 'elflord' colorscheme will give you the most
"       distinctive colors.
"
" ================================================================
"
" OPTIONS:
"
"    Many of these default to 1 (On), so you would need to set
"	 them to 0 to turn them off. E.g., in your .vimrc file:
"      let php_special_vars = 0
"      let php_special_functions = 0
"      let php_alt_comparisons = 0
"      etc.
"    If the variables do not exist, the default value will be used.
"
"
"    All options can be set globally or on a per-file basis by using
"    global or buffer-local variables.  For example, you could turn on
"    automatic folding for all PHP scripts in your .vimrc:
"      let g:php_folding = 3
"
"    Then you could turn it off in only one file using this command:
"
"      :let b:php_folding = 0 | setfiletype php
"
"
"   -- PHP FEATURES --
"
"         let php_sql_query = 1/0  [default 0]
"             ... for SQL syntax highlighting inside strings
"
"         let php_htmlInStrings = 1/0  [default 0]
"             ... for HTML syntax highlighting inside strings
"
"         let php_baselib = 1/0  [default 0]
"             ... for highlighting baselib functions
"
"         let php_special_vars = 1/0  [default 1]
"             ... to highlight superglobals like $_GET, $_SERVER, etc.
"               * always on if using php_oldStyle
"
"         let php_special_functions = 1/0  [default 1]
"             ... to highlight functions with special behaviour
"                 e.g., unset(), extract()
"
"         let php_alt_comparisons = 1/0  [default 1]
"             ... to highlight comparison operators in an alternate colour
"               * always on if using php_oldStyle
"
"         let php_alt_assignByReference = 1/0  [default 1]
"             ... to highlight '=&' in '$foo =& $bar' in an alternate colour.
"                 This also applies to a function which returns by-reference,
"                 as well as a function argument which is by-reference.
"
"         let php_smart_members = 1/0  [default 0]
"             ... syntax works out whether -> indicates a property or method.
"                 Otherwise method colours may be used on properties, for
"                 example:
"                   $object->__get[] = true;
"                 '__get' would be highlighted as a special method, even
"                 thought it is clearly a property in this context.
"                 Note: turning this OFF can improve the highlighting speed on
"                 object-oriented code
"
"         let php_alt_properties = 1/0  [default 0]
"             ... use a different color for '->' based on whether it is used
"                 for property access, method access, or dynamic access (using
"                 '->{...}')
"               * requires php_smart_members
"
"         let php_highlight_quotes = 1/0  [default 0]
"             ... makes quote characters the same colour as the string
"                 contents, like in C syntax.
"
"         let php_show_semicolon = 1/0  [default 1]
"             ... to make the semicolon (;) more visible
"
"         let php_smart_semicolon = 1/0  [default 1]
"             ... semicolon adopts the color of a 'return' or 'break' keyword
"               * requires php_show_semicolon
"                 Note: this also includes the ':' or ';' which follows a
"                 'case' or 'default' inside a switch
"
"         let php_alt_blocks = 1/0  [default 1]
"             ... colorize { and } around class/function/try/catch bodies
"                 according to the type of code block.
"               * requires php_strict_blocks
"
"         let php_alt_arrays = 0/1/2  [default 1]
"             ... to colorize ( and ) around an array body, as well as '=>'
"               * requires php_strict_blocks
"                 Setting this to '2' will highlighting the commas as well.
"                 Commas are not highlighted by default because it's too much
"                 color.
"
"         let php_alt_construct_parents = 0/1  [default 0]
"             ... to colorize the ( and ) around an if, while, foreach, or switch
"                 body.
"               * requires ... what?
"                 TODO: work out dependencies, code them correctly
"
"         let php_show_spl = 1/0  [default 1]
"             .. to colorize methods which are defined by PHP default interfaces
"                TODO: work out what these interfaces are part of: SPL or just
"                PHP
"
"         let php_show_pcre = 1/0  [default 1]
"                 (was: 'php_show_preg')
"             ... to highlight regular expression patterns inside calls
"                 to preg_match(), preg_replace(), etc.
"
"
"   -- FINDING ERRORS --
"
"         let php_parent_error_close = 1/0  [default 1]
"             ... for highlighting parent error ] or ) or }
"               * requires php_strict_blocks
"
"         let php_parent_error_open = ?
"             ... for skipping a php end tag, if there exists an
"                 open ( or [ without a closing one
"                 Note: this option is now enabled permanently (unless
"                 php_strict_blocks is disabled).
"               * requires php_strict_blocks
"
"         let php_empty_construct_error = 0/1  [default 1]
"             ... highlights ';' as an error if it comes immediately after
"                 an if/else/while/for/foreach/switch statement (the
"                 logical constructs should have a body).
"               * requires php_strict_blocks

"         let php_show_semicolon_error = 1/0  [default 1]
"             ... highlights certain cases when ';' is followed by an
"                 operator such as '+'.
"               * requires php_show_semicolon
"
"         let php_nested_functions = 0/1  [default 0]
"             ... Whether or not to allow contiaining one function inside
"                 another.  This option is mostly for speeding up syntax
"                 highlighting - { } blocks can by inserted much faster while
"                 editting a large class.
"                 Note: this is the only option which might break valid PHP
"                 code, although only if you define one function inside
"                 another, which is usually discouraged.
"               * only relevant when using php_strict_blocks
"
"   -- OTHER OPTIONS --
"
"         let php_large_file = 0/?  [ default 3000 ]
"             ... If a PHP script has more lines than this limit (e.g., more
"                 than 3000 lines), some options are automatically turned off
"                 to help it load faster.  These options are:
"                   php_strict_blocks = 0
"                   php_smart_members = 0
"                   php_smart_semicolon = 0
"                   php_show_pcre = 0
"                   php_folding = 0
"                 Note: If you set this option to '0', then this feature will
"                 be disabled; thus you can use:
"                   :let b:php_large_file = 0 | setfiletype php
"                 to reload the current file with the disabled syntax options
"                 re-activated.
"
"         let php_strict_blocks = 1/0  [default 1]
"             ... to match together all {} () and [] blocks correctly. This is
"                 required by some of the other options for finding errors and
"                 applying correct colors to { } blocks, etc.  However, it may
"                 cause Vim to slow down on large files.
"
"         let php_asp_tags = 1/0  [default 0]
"             ... for highlighting ASP-style short tags: <% %>
"
"         let php_noShortTags = 1/0  [default 0]
"             ... don't sync <? ?> as php
"               * This has been deprecated in favour of php_short_tags (which
"                 has the opposite meaning)
"
"         let php_short_tags = 1/0  [default 1]
"             ... highlight <?...?> blocks as php. If this is OFF, you need to
"                 use the longer <?php...?>
"
"         let php_oldStyle = 1
"             ... for using old colorstyle
"
"         let php_folding = 1/2/3  [default 0]
"             ... 1: for folding classes and functions
"                 2: for folding all { } regions
"                 3: for folding only functions

"
" ================================================================
"
" TODO LIST:
"
" PRIORITY:
"   - document the phpControlParent feature, make sure it works fully, or not
"     at all
"   - what to do about 'iskeyword' containing '$'?
"   - test syntax against older Vims (6.4, 6.0, 5.7)
"   - concat rid of lines beginning with '\'
"   - allow turning off all semicolon errors
"   - fix bug in highlighting of pattern: /[\\\]/ and /[\\]]/
"   - fix bug in highlighting of pattern: "/\$/" should make the '$' match the
"     end-of-pattern
"   - case/default syntax items don't work inside a switch/endswitch
"     although it's still OK using {...}
"
" PHP Syntax:
"   - review support for PHP built-in superglobals:
"     - ensure all PHP 5.2 superglobals are recognized
"   - review support for PHP built-in constants, make sure I've got them all
"   - make support for PHP built-in class methods optional.
"   - review highlight links to ensure maximum readability on GUI
"     and color terminal using colorschemes 'elflord' and 'default'
"   - new group phpReservedFunction, because some parts of
"     phpSpecialFunction can be used as a method name.
"   - what is php_oldStyle? is it still needed?
"   - use 'nextgroup' to highlight errors when a ']' or ')' is followed by
"     a constant/variable or function call.  This will also help find when
"     a closing ')' is missing.
"   - Review syncing searches, see if there is anything we can add to help the
"     syncing process.
"   - make ';' on the end of a while() NOT a problem unless it is followed by
"     a '{'
"
" PCRE Syntax:
"   - fix problem: in regex "/(...)\1/", '\1' does NOT refer to a backreference!
"     this is caused by incorrect matching of escape sequences in
"     double-quoted strings where the double-quote escape sequences should
"     take precedence
"   - fix problem: this line breaks folding
"   		preg_match("#^require MODULES_PATH \. (['\"])main\.inc\.php\\1;$#m", '', $m))
"
"   - decide on terminology: 'PCRE' or 'PREG'
"   - Review effects of paired delimiters when combined with other
"     PCRE complex atoms using those symbols
"   - decide on better colors for the
"     (?(?=lookahead/lookbehind)conditional|sub-pattern)
"
"
" Future Plans:
"   - option to choose PHP4 or PHP5 compatibility
"   - differentiate between an interface block and a class block
"   - add ability to highlight user-defined functions and keywords
"     using any of the following means:
"       1) a comma-separated string of user functions
"       2) a file containing user functions
"       3) using names from the tags file(s)
"           (this may be better as a separate plugin)
"   - add support for phpDocumentor comment blocks and tags
"   - add support for POSIX Regex patterns
"   - allow easy embedding of the PHP syntax using 'contains=@phpClTop' or
"     'syn region phpRegion ...'
"   - automatically select best colors by examining the colorscheme
"   - check to see if 'baselib' needs to be highlighted still
"   - Add support 2nd parameter to preg_replace and highlight
"     "\1" and other confusing sequences as errors ("\1" is "\x01")
"   - Add support for class constants (foo::bar)
"
" Difficult To Implement:
"   - Highlight expressions without operators or commas, such as:
"       echo $a $b;
"     These expressions are *really* difficult to find efficiently.
"   - Folding around 'case' blocks.
"
"
"
" ================================================================
"
" Note:
" - syntax case is 'ignore' unless explicitly set to 'match'
"   for a single item.

" For version 6.x: Quit when a syntax file was already loaded
