Class: search_token  - X-Ref

Class to hold token/value pairs after they're parsed.

__construct($type,$value)   X-Ref
No description

search_token($type, $value)   X-Ref
Old syntax of class constructor. Deprecated in PHP7.


sanitize($userstring)   X-Ref
No description

getValue()   X-Ref
No description

getType()   X-Ref
No description

Class: search_lexer  - X-Ref

This class does the heavy lifting of lexing the search string into tokens.
Using a full-blown lexer is probably overkill for this application, but
might be useful for other tasks.

__construct(&$parser)   X-Ref
No description

search_lexer(&$parser)   X-Ref
Old syntax of class constructor. Deprecated in PHP7.


Class: search_parser  - X-Ref

This class takes care of sticking the proper token type/value pairs into
the parsed token  array.
Most functions in this class should only be called by the lexer, the
one exception being getParseArray() which returns the result.

get_parsed_array()   X-Ref

search_generate_text_SQL($parsetree, $datafield, $metafield, $mainidfield, $useridfield,$userfirstnamefield, $userlastnamefield, $timefield, $instancefield)   X-Ref
Primitive function to generate a SQL string from a parse tree
using TEXT indexes. If searches aren't suitable to use TEXT
this function calls the default search_generate_SQL() one.


search_generate_SQL($parsetree, $datafield, $metafield, $mainidfield, $useridfield,$userfirstnamefield, $userlastnamefield, $timefield, $instancefield)   X-Ref
Primitive function to generate a SQL string from a parse tree.
Parameters:

$parsetree should be a parse tree generated by a
search_lexer/search_parser combination.
Other fields are database table names to search.
