Based on Hal Helms' QuerySim.cfm ColdFusion - custom tag available at halhelms.com. - - - - - - - - Extensive revision that is backwardly compatible but eliminates the - need for a separate .sim file. - - - Rewrote in PHP as an extention to the PEAR DB API. - Functions supported: - connect, disconnect, query, fetchRow, freeResult, - numCols, numRows, getSpecialQuery - David Huyck (bombusbee.com) added ability to escape special - characters (i.e., delimiters) using a '\'. - Extended PEAR DB options[] for adding incoming parameters. Added - options: columnDelim, dataDelim, eolDelim - - - Added the ability to set the QuerySim options at runtime. - Default options are: - 'columnDelim' => ',', // Commas split the column names - 'dataDelim' => '|', // Pipes split the data fields - 'eolDelim' => chr(13).chr(10) // Carriage returns split the - // lines of data - Affected functions are: - DB_querysim(): set the default options when the - constructor method is called - _parseQuerySim($query): altered the parsing of lines, column - names, and data fields - _empty2null: altered the way this function is called - to simplify calling it - - - Added error catching for malformed QuerySim text. - Bug fix _empty2null(): altered version was returning unmodified - lineData. - Cleanup: - PEAR compliant formatting, finished PHPDocs and added 'out' to - Fusedoc 'io'. - Broke up _parseQuerySim() into _buildResult() and _parseOnDelim() - to containerize duplicate parse code. - - - Edited the _buildResult() and _parseOnDelim() functions to improve - reliability of special character escaping. - Re-introduced a custom setOption() method to throw an error when a - person tries to set one of the delimiters to '\'. - - - Added '/' delimiter param to preg_quote() in _empty2null() and - _parseOnDelim() so '/' can be used as a delimiter. - Added error check for columnDelim == eolDelim or dataDelim == eolDelim. - Renamed some variables for consistancy. - - - Removed protected function _empty2null(). Turns out preg_split() - deals with empty elemants by making them zero length strings, just - what they ended up being anyway. This should speed things up a little. - Affected functions: - _parseOnDelim() perform trim on line here, instead of in - _empty2null(). - _buildResult() remove call to _empty2null(). - _empty2null() removed function. - - - Ported to PEAR MDB2. - Methods supported: - connect, query, getColumnNames, numCols, valid, fetch, - numRows, free, fetchRow, nextResult, setLimit - (inherited). - - - - Changed default eolDelim to a *nix file eol, since we're trimming - the result anyway, it makes no difference for Windows. Now only - Mac file eols should need to be set (and other kinds of chars). - - - Got WAY too long. See querysim_readme.txt for instructions and some - examples. - io section only documents elements of DB_result that DB_querysim uses, - adds or changes; see MDB2 and MDB2_Driver_Common for more info. - io section uses some elements that are not Fusedoc 2.0 compliant: - object and resource. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -*/ - -/** - * MDB2 QuerySim driver - * - * @package MDB2 - * @category Database - * @author Alan Richmond - */ -class MDB2_Driver_querysim extends MDB2_Driver_Common -{ - // {{{ properties - var $escape_quotes = "\\";
