See the Advantage PHP 40 help file topic for ads_connect for details on connection path options 41 and formatting. 42 5 - (optional) - Modify the Delphi for PHP\X.X\vcl\packages\database.packages.php 43 file and add ads to the list of strings returned when registering the 44 Database object's DriverName property. 45 46*/ 47 48// security - hide paths 49if (!defined('ADODB_DIR')) { 50 die(); 51} 52 53define("_ADODB_ADS_LAYER", 2); 54 55/*-------------------------------------------------------------------------------------- 56--------------------------------------------------------------------------------------*/ 57 58 59class ADODB_ads extends ADOConnection 60{ 61 var $databaseType = "ads"; 62 var $fmt = "'m-d-Y'"; 63 var $fmtTimeStamp = "'Y-m-d H:i:s'"; 64 var $concat_operator = ''; 65 var $replaceQuote = "''"; // string to use to replace quotes 66 var $dataProvider = "ads"; 67 var $hasAffectedRows = true; 68 var $binmode = ODBC_BINMODE_RETURN; 69 var $useFetchArray = false; // setting this to true will make array elements in FETCH_ASSOC mode case-sensitive 70 // breaking backward-compat 71 //var $longreadlen = 8000; // default number of chars to return for a Blob/Long field 72 var $_bindInputArray = false; 73 var $curmode = SQL_CUR_USE_DRIVER; // See sqlext.h, SQL_CUR_DEFAULT == SQL_CUR_USE_DRIVER == 2L 74 var $_genSeqSQL = "create table %s (id integer)"; 75 var $_autocommit = true; 76 var $_lastAffectedRows = 0; 77 var $uCaseTables = true; // for meta* functions, uppercase table names 78 79 function __construct() 80 { 81 } 82 83 // returns true or false 84 function _connect($argDSN, $argUsername, $argPassword, $argDatabasename) 85 { 86 if (!function_exists('ads_connect')) { 87 return null; 88 } 89 90 if ($this->debug && $argDatabasename && $this->databaseType != 'vfp') { 91 ADOConnection::outp("For Advantage Connect(), $argDatabasename is not used.
