use output in sql code example

Example 1: sql insert inserted id

-- Never use @@identity or scope_identity()
-- they can not always be relied upon

DECLARE @Ids_tbl TABLE ([id] INT); -- Requires table. use variable for scope
INSERT INTO [sometable] ([ColA],[ColB])
OUTPUT INSERTED.ID INTO @Ids_tbl(id)
VALUES ('valA','valB');

SELECT [id] FROM @Ids_tbl; -- <-- Id(s) in here

Example 2: output data in sql

<?php
	/* Connect to your database */
	$con = mysqli_query("hostname", "username", "pwd", "database");
    /* Select Columns from table*/
    $sql = "SELECT * FROM `TABLE`";
    /* Query your SQL code to SQLDatabase */
    $result = mysqli_query($con, $sql);
    /* Find rows in table*/
    $check = mysqli_num_rows($result);
    if($check > 0){
    while($data= mysqli_fetch_assoc($result)){
    /* Print all of your data*/
    echo $data["ColName"];
    }
    }
?>
