The function executes a statement and returns all of the returned rows in an array or false if the statement execution fails, or if only 1 column is requested in the SQL statement. If no records match the provided SQL statement, an empty array is returned.

The presentation of certain aspects of the returned data can be modified by the constant ADODB_ASSOC_CASE (see below for examples).

For a detailed description of the SQL and bind parameters passed, see execute().

In addition it should be noted that the presentation of the returned data is modified by the number of columns requested in the SQL statement and the setting of the optional parameters $forceArray and $first2Cols.

When 2 columns are requested, the first column becomes the key and the second the value.

/*
 * DB2 Connection assumed
*/
$ar = $db->getAssoc("SELECT ACTNO,ACTDESC FROM ACT");
 
/*
 * $ar returns:
Array
(
    [10] => MANAGE/ADVISE
    [20] => ESTIMATE COST
    [30] => DEFINE SPECS
    [40] => LEAD PROGRAM/DESIGN
 ......
)
*/
 

When more than 2 columns are requested, the first column becomes the key, all other columns become a numeric array beneath that key.

/*
 * DB2 Connection assumed
*/
$ar = $db->getAssoc("SELECT * FROM ACT");
 
/*
 * $ar returns:
Array
(
    [10] => Array
        (
            [0] => MANAGE
            [1] => MANAGE/ADVISE
        )
 
    [20] => Array
        (
            [0] => ECOST
            [1] => ESTIMATE COST
        )
 
    [30] => Array
        (
            [0] => DEFINE
            [1] => DEFINE SPECS
        )
 
 ......
)
*/
 

When 2 columns are requested and the $forceArray boolean is set, the first column becomes the key and the second becomes an array beneath that key.

/*
 * DB2 Connection assumed
*/
$ar = $db->getAssoc("SELECT ACTNO,ACTDESC FROM ACT",false,true);
 
/*
 * $ar returns:
   Array
(
    [10] => Array
        (
            [0] => MANAGE/ADVISE
        )
 
    [20] => Array
        (
            [0] => ESTIMATE COST
        )
 
    [30] => Array
        (
            [0] => DEFINE SPECS
        )
 ......
)
*/
 

When more than 2 columns are requested, and the $first2cols flag is set, the behaviour is the same as the default configuration. The $forceArray flag is ignored. All columns after the first two are discarded.

/*
 * DB2 Connection assumed
*/
$ar = $db->getAssoc("SELECT * FROM ACT",false,false,true);
 
/*
 * $ar returns:
Array
(
    [10] => MANAGE/ADVISE
    [20] => ESTIMATE COST
    [30] => DEFINE SPECS
    [40] => LEAD PROGRAM/DESIGN
 ......
)
*/
 

In certain instances, the ADODB_ASSOC_CASE constant changes the casing of inner keys. The casing of outer keys is never affected, so in this first example, the data will always be returned as it appears in the database

/*
* Connection to mysql 'employees' database assumed.
*/
$SQL = "SELECT first_name,last_name from employees";
$r = $db->getAssoc($SQL);
print_r($r);
/*
* Returns: 
Array
(
    [Georgi] => Wielonsky
    [Bezalel] => Ranon
    [Parto] => Kambil
    ........
)
*/

Setting ADODB_ASSOC_CASE to ASSOC_CASE_LOWER:

/*
* Connection to mysql 'employees' database assumed.
*/
$SQL = "SELECT first_name,last_name,emp_no from employees";
$r = $db->getAssoc($SQL);
print_r($r);
/*
* Returns: 
Array
(
    [Georgi] => Array
        (
            [last_name] => Wielonsky
            [emp_no] => 499814
        )
 
    [Bezalel] => Array
        (
            [last_name] => Ranon
            [emp_no] => 499846
        )
 
    [Parto] => Array
        (
            [last_name] => Kambil
            [emp_no] => 499529
        )
    .......
 )
*/ 

Setting ADODB_ASSOC_CASE to ASSOC_CASE_UPPER:

/*
* Connection to mysql 'employees' database assumed.
*/
$SQL = "SELECT first_name,last_name,emp_no from employees";
$r = $db->getAssoc($SQL);
print_r($r);
/*
* Returns: 
Array
Array
(
    [Georgi] => Array
        (
            [LAST_NAME] => Wielonsky
            [EMP_NO] => 499814
        )
 
    [Bezalel] => Array
        (
            [LAST_NAME] => Ranon
            [EMP_NO] => 499846
        )
 
    [Parto] => Array
        (
            [LAST_NAME] => Kambil
            [EMP_NO] => 499529
        )
    .......
 )
*/ 

The method can also be used as a recordset method

$ar = $db->Execute("SELECT * FROM ACT")->getAssoc();
