BASH doesn't have boolean types. The existence of a program named 'true' doesn't change this.
BASH doesn't have associative arrays, either. You can't use words as array indexes.
That's a bit of a problem. Doing

man bash
in section arrays, says that Bash provides one-dimensional indexed and associative array variables. Should work from bash 4.0 onward.
ksh should have associative arrays and can use the same logic. What would be the alternative to the true/false scheme I used. For single variables, the true/false should work. Or am I wrong in the conclusion. I tried it and did not encounter a problem.

sqlsrv_fetch_array
SQLSRV_FETCH_ARRAY(3)SQLSRV_FETCH_ARRAY(3)sqlsrv_fetch_array - Returns a row as an arraySYNOPSIS
array sqlsrv_fetch_array (resource $stmt, [int $fetchType], [int $row], [int $offset])
DESCRIPTION
Returns the next available row of data as an associative array, a numeric array, or both (the default).
PARAMETERS
o $stmt
- A statement resource returned by sqlsrv_query or sqlsrv_prepare.
o $fetchType
- A predefined constant specifying the type of array to return. Possible values are SQLSRV_FETCH_ASSOC, SQLSRV_FETCH_NUMERIC, and
SQLSRV_FETCH_BOTH (the default). A fetch type of SQLSRV_FETCH_ASSOC should not be used when consuming a result set with multiple
columns of the same name.
o $row
- Specifies the row to access in a result set that uses a scrollable cursor. Possible values are SQLSRV_SCROLL_NEXT, SQL-
SRV_SCROLL_PRIOR, SQLSRV_SCROLL_FIRST, SQLSRV_SCROLL_LAST, SQLSRV_SCROLL_ABSOLUTE and, SQLSRV_SCROLL_RELATIVE (the default). When
this parameter is specified, the $fetchType must be explicitly defined.
o $offset
- Specifies the row to be accessed if the row parameter is set to SQLSRV_SCROLL_ABSOLUTE or SQLSRV_SCROLL_RELATIVE. Note that the
first row in a result set has index 0.
RETURN VALUES
Returns an array on success, NULL if there are no more rows to return, and FALSE if an error occurs.
EXAMPLES
Example #1
Retrieving an associative array.
<?php
$serverName = "serverNameinstanceName";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo );
if( $conn === false ) {
die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT FirstName, LastName FROM SomeTable";
$stmt = sqlsrv_query( $conn, $sql );
if( $stmt === false) {
die( print_r( sqlsrv_errors(), true) );
}
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
echo $row['LastName'].", ".$row['FirstName']."<br />";
}
sqlsrv_free_stmt( $stmt);
?>
Example #2
Retrieving a numeric array.
<?php
$serverName = "serverNameinstanceName";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo );
if( $conn === false ) {
die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT FirstName, LastName FROM SomeTable";
$stmt = sqlsrv_query( $conn, $sql );
if( $stmt === false) {
die( print_r( sqlsrv_errors(), true) );
}
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_NUMERIC) ) {
echo $row[0].", ".$row[1]."<br />";
}
sqlsrv_free_stmt( $stmt);
?>
NOTES
Not specifying the $fetchType or explicity using the SQLSRV_FETCH_TYPE constant in the examples above will return an array that has both
associative and numeric keys.
If more than one column is returned with the same name, the last column will take precedence. To avoid field name collisions, use aliases.
If a column with no name is returned, the associative key for the array element will be an empty string ("").
