sqlsrv_fetch_array — Returns a row as an array
Description
$stmt
[, int $fetchType
[, int $row
[, int $offset
]]] )Returns the next available row of data as an associative array, a numeric array, or both (the default).
Parameters
-
stmt -
A statement resource returned by sqlsrv_query or sqlsrv_prepare.
-
fetchType -
A predefined constant specifying the type of array to return. Possible values are
SQLSRV_FETCH_ASSOC,SQLSRV_FETCH_NUMERIC, andSQLSRV_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.
-
row -
Specifies the row to access in a result set that uses a scrollable cursor. Possible values are
SQLSRV_SCROLL_NEXT,SQLSRV_SCROLL_PRIOR,SQLSRV_SCROLL_FIRST,SQLSRV_SCROLL_LAST,SQLSRV_SCROLL_ABSOLUTEand,SQLSRV_SCROLL_RELATIVE(the default). When this parameter is specified, thefetchTypemust be explicitly defined. -
offset -
Specifies the row to be accessed if the row parameter is set to
SQLSRV_SCROLL_ABSOLUTEorSQLSRV_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 = "serverName\instanceName";
$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 = "serverName\instanceName";
$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 ("").

Example with an iteration ( SQLSRV_SCROLL_ABSOLUTE ).
for ($i=0; $i < sqlsrv_num_rows($stmt); $i++) {
$row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_NUMERIC, SQLSRV_SCROLL_ABSOLUTE , $i );
echo "value of column 1: '.trim($row[0]).', value of column 2: '.trim($row[1]);
}
