I don't know the grammar error in php...

The error appears as follows:
It seems to be a grammatical error, but is it written incorrectly?

Error:
Parse error: syntax error, unexpected '$_SESSION'(T_VARIABLE), expecting', 'or'; 'in/var/www/html/php_kadai/php_kadai09/postdone.php on line48

Where applicable:

<?phpecho"<img src="$_SESSION["img_data"]"><br><br>br>";?>




<?php
require_once('functions.php');
session_start();

var_dump($_SESSION["img_data"]);

// $name = $_POST ['name'];
// $image_name = $_POST ['image_name'];
// $img_data="images/".$_FILES["img_data"]["name"];

// $dbh = connectDb();
// $sql="insert into posts(create_at, name, image_name, img_data) values
//         (now(), :name, :image_name, :img_data)";
// $stmt = $dbh->prepare($sql);
// $stmt->bindParam(":name", $name);
// $stmt->bindParam(":image_name", $image_name);
// $stmt->bindParam(":img_data", $img_data);


// $stmt->execute();

<?phpecho"<img src="$_SESSION["img_data"]">br>br>br>";?> portion

You must escape with \ to write " in the string, i.e., " and ".
So, I'll write it like this.
echo"<img src=\"$_SESSION[img_data]\">br>br>br>";

The "img_data" portion does not write " if it is embedded in a string.

"<img src="$_SESSION["img_data"]">br>br>br>br>"

Because the string enclosed by two " ("<img src=" and "<br>"<br>") and one variable ($_SESSION["img_data"]) must be combined.

"<img src=".$_SESSION["img_data"].">br>br>br>br>"
