Create PHP apps using SQL Server on Windows (ok)

https://www.microsoft.com/en-us/sql-server/developer-get-started/php/windows/step/2.html

Step 2.1 Install the PHP Drivers for SQL Server

Download the Microsoft PHP Drivers for SQL Server from the download page.

Pick the appropriate dll - for example php_pdo_sqlsrv_74_nts.dll for the PDO Driver and php_sqlsrv_74_nts.dll for the SQLSRV driver.

Copy the dll files to the C:\Program Files\iis express\PHP\v7.4\ext folder.

Register the dll files in the php.ini file.Terminal

cd C:\Program^ Files\iis^ express\PHP\v7.4\ext
echo extension=php_sqlsrv_74_nts.dll >> C:\Program^ Files\iis^ express\PHP\v7.4\php.ini
echo extension=php_pdo_sqlsrv_74_nts.dll >> C:\Program^ Files\iis^ express\PHP\v7.4\php.ini Copy

Step 2.2 Create a database for your application

Create the database using sqlcmd.Terminal

sqlcmd -S localhost -U sa -P your_password -Q "CREATE DATABASE SampleDB;" Copy

Step 2.3 Create a PHP app that connects to SQL Server and executes queries

Terminal

mkdir SqlServerSample
cd SqlServerSample Copy

Using your favorite text editor, create a new file called connect.php in the SqlServerSample folder. Paste the code below inside into the new file.PHP

<?php
    $serverName = "localhost";
    $connectionOptions = array(
        "Database" => "SampleDB",
        "Uid" => "sa",
        "PWD" => "your_password"
    );
    //Establishes the connection
    $conn = sqlsrv_connect($serverName, $connectionOptions);
    if($conn)
        echo "Connected!"
?> Copy

Run your PHP script from the terminal.Terminal

php connect.php Copy

Results

Connected!

Execute the T-SQL scripts below in the terminal with sqlcmd to create a schema, table, and insert a few rows.Terminal

sqlcmd -S localhost -U sa -P your_password -d SampleDB -Q "CREATE SCHEMA TestSchema;"
sqlcmd -S localhost -U sa -P your_password -d SampleDB -Q "CREATE TABLE TestSchema.Employees (Id INT IDENTITY(1,1) NOT NULL PRIMARY KEY, Name NVARCHAR(50), Location NVARCHAR(50));"
sqlcmd -S localhost -U sa -P your_password -d SampleDB -Q "INSERT INTO TestSchema.Employees (Name, Location) VALUES (N'Jared', N'Australia'), (N'Nikita', N'India'), (N'Tom', N'Germany');"
sqlcmd -S localhost -U sa -P your_password -d SampleDB -Q "SELECT * FROM TestSchema.Employees;" Copy

Using your favorite text editor, create a new file called crud.php in the SqlServerSample folder. Paste the code below inside into the new file. This will insert, update, delete, and read a few rows.PHP

<?php
$serverName = "localhost";
$connectionOptions = array(
    "Database" => "SampleDB",
    "Uid" => "sa",
    "PWD" => "your_password"
);

//Establishes the connection
$conn = sqlsrv_connect($serverName, $connectionOptions);

//Insert Query
echo ("Inserting a new row into table" . PHP_EOL);
$tsql= "INSERT INTO TestSchema.Employees (Name, Location) VALUES (?,?);";
$params = array('Jake','United States');
$getResults= sqlsrv_query($conn, $tsql, $params);
$rowsAffected = sqlsrv_rows_affected($getResults);
if ($getResults == FALSE or $rowsAffected == FALSE)
    die(FormatErrors(sqlsrv_errors()));
echo ($rowsAffected. " row(s) inserted: " . PHP_EOL);

sqlsrv_free_stmt($getResults);

//Update Query

$userToUpdate = 'Nikita';
$tsql= "UPDATE TestSchema.Employees SET Location = ? WHERE Name = ?";
$params = array('Sweden', $userToUpdate);
echo("Updating Location for user " . $userToUpdate . PHP_EOL);

$getResults= sqlsrv_query($conn, $tsql, $params);
$rowsAffected = sqlsrv_rows_affected($getResults);
if ($getResults == FALSE or $rowsAffected == FALSE)
    die(FormatErrors(sqlsrv_errors()));
echo ($rowsAffected. " row(s) updated: " . PHP_EOL);
sqlsrv_free_stmt($getResults);

//Delete Query
$userToDelete = 'Jared';
$tsql= "DELETE FROM TestSchema.Employees WHERE Name = ?";
$params = array($userToDelete);
$getResults= sqlsrv_query($conn, $tsql, $params);
echo("Deleting user " . $userToDelete . PHP_EOL);
$rowsAffected = sqlsrv_rows_affected($getResults);
if ($getResults == FALSE or $rowsAffected == FALSE)
    die(FormatErrors(sqlsrv_errors()));
echo ($rowsAffected. " row(s) deleted: " . PHP_EOL);
sqlsrv_free_stmt($getResults);


//Read Query
$tsql= "SELECT Id, Name, Location FROM TestSchema.Employees;";
$getResults= sqlsrv_query($conn, $tsql);
echo ("Reading data from table" . PHP_EOL);
if ($getResults == FALSE)
    die(FormatErrors(sqlsrv_errors()));
while ($row = sqlsrv_fetch_array($getResults, SQLSRV_FETCH_ASSOC)) {
    echo ($row['Id'] . " " . $row['Name'] . " " . $row['Location'] . PHP_EOL);
}
sqlsrv_free_stmt($getResults);

function FormatErrors( $errors )
{
    /* Display errors. */
    echo "Error information: ";

    foreach ( $errors as $error )
    {
        echo "SQLSTATE: ".$error['SQLSTATE']."";
        echo "Code: ".$error['code']."";
        echo "Message: ".$error['message']."";
    }
}
?> Copy

Run your PHP script from the terminal.Terminal

php crud.php Copy

Results

Inserting a new row into table
1 row(s) inserted:
Updating Location for user Nikita
1 row(s) updated:
Deleting user Jared
1 row(s) deleted:
Reading data from table
2 Nikita Sweden
3 Tom Germany
4 Jake United States
