How can PHP developers effectively troubleshoot and debug SQL queries in PHP when using sqlsrv_fetch_array()?

When using sqlsrv_fetch_array() in PHP to retrieve data from SQL queries, developers can effectively troubleshoot and debug by checking for errors returned by the sqlsrv_query() function and using functions like sqlsrv_errors() to get detailed error information. Additionally, developers can echo out the SQL query being executed to ensure it is correct and examine the data returned by sqlsrv_fetch_array() to identify any discrepancies. 

// Execute SQL query
$query = "SELECT * FROM table_name";
$result = sqlsrv_query($conn, $query);

// Check for errors
if($result === false) {
    die(print_r(sqlsrv_errors(), true));
}

// Debug SQL query
echo "SQL Query: " . $query . "<br>";

// Fetch data
while($row = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC)) {
    // Process data
}
