Get ID of Last Entery in MSSQL Server via PHP - php

Question

Hello i need a little Help.
I have a MSSQL Server and i need the ID of the Last Entery.
My PHP Code is:
$conn = sqlsrv_connect( $serverName, $connectionInfo);
$sqlnextid = "Select IDENT_CURRENT('dbo.Person')";
echo $sqlnextid;
$nextid = sqlsrv_query( $conn, $sqlnextid );
echo $nextid;
Unfortunately $nextid only returns "Resource id#3" and not the correct ID in the SQL Management Studio. The sql query "Select IDENT_CURRENT('dbo.Person')" works fine an give the correct answer - (33).
Where is my mistake? Thanks in advance :)

You need to fetch the data from the executed query uisng sqlsrv_fetch_array(). As is explained in the documentation, the function sqlsrv_query() returns a statement resource or false if the statement cannot be created and/or executed.
As a side note, always check the result from the sqlsrv_connect() and sqlsrv_query() calls.
<?php
...
// Connection
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false ) {
echo "Error (sqlsrv_connect): ".print_r(sqlsrv_errors(), true);
exit;
}
// Query
$sqlnextid = "SELECT IDENT_CURRENT('dbo.Person') AS [CurrentIdent]";
$stmt = sqlsrv_query( $conn, $sqlnextid );
if( $stmt === false ) {
echo "Error (sqlsrv_query): ".print_r(sqlsrv_errors(), true);
exit;
}
// Data
$ident = 0;
while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
$ident = $row["CurrentIdent"];
}
echo $ident;
...
?>

sqlsrv_query returns returns a statement resource on success and FALSE if an error occurred.
You can access the result using sqlsrv_fetch_object.
$sqlnextid = "SELECT IDENT_CURRENT('dbo.Person') AS LastId"
$result = sqlsrv_query($conn, $sqlnextid);
$row = sqlsrv_fetch_object($result)
echo $row->LastId;
