Read the Session Data from Session Storage File

Read the session data from session storage file

If you want to decode session data, use session_decode (see the manual). unserialize only decodes single variables, not session data.

You can do something like:

$file = '/var/www/html/products/var/session/sess_ciktos8icvk11grtpkj3u610o3';
$contents = file_get_contents($file);
session_start();
session_decode($contents);
print_r($_SESSION);

Reading PHP's session data without loading it

I would start both sessions one by one and store $_SESSION value in local arrays.

i.e.

// Loading the first session.
session_name('first_session_name');
session_start();
// Now we have first session variables available in $_SESSION
$_FIRST_SESSION = $_SESSION;
// End current session.
session_write_close();
// Just to make sure nothing remains in the session.
unset($_SESSION);
// Now set the second session name.
session_name('second_session_name');
// Check and see if the second session name has a session id.
if (isset($_COOKIE['second_session_name']))
    // There's already a session id for this name.
    session_id($_COOKIE['second_session_name']);
else
    // We need to generate a new session id as this is the first time.
    session_id(sha1(mt_rand()));
session_start();
$_SECOND_SESSION = $_SESSION;

PHP Laravel: How to set or get Session Data?

Storing data

To store data, you can use:

Session::put('variableName', $value);

There is also another way, through the global helper:

session(['variableName' => $value]);

Getting data

To get the variable, you'd use:

Session::get('variableName');

Session Storage in js

Session storage is same as local storage but the only difference is that data stored in session storage will clear automatically once page session will expire.

Now come to your question. In your success function, do like below to store data:

success : function(data) {
    console.log(data.xhr.response);
    sessionStorage.setItem('dataStored', data.xhr.response);

}

Usage is like below:

// Save data to sessionStorage
sessionStorage.setItem('dataStored', data.xhr.response);

// Get saved data from sessionStorage
var data = sessionStorage.getItem('dataStored');

// Remove saved data from sessionStorage
sessionStorage.removeItem('dataStored');

// Remove all saved data from sessionStorage
sessionStorage.clear();

Where is sessionStorage data stored?

It's not stored on the server, since we're still in client side when you're talking about Window.sessionStorage. It's stored in a file called "sessionstore.jsonlz4". In any case, this question has an answer here.

How to store and read session (value) in AngularJs?

Your session storage code could look something like this using Javascript APIs for session storage. You will have to serialize your Javascript object as session storage only supports strings.

$scope.returnRefId = function (emp) {           
        try {
              //  test emp
              alert(emp);
              // session code here
              sessionStorage.setItem("emp-key", JSON.stringify(emp));
        }
        catch (e) {
              alert("some errror");
        }
 };

Alternatively, you can storage each property of emp in a separate storage key. Debugging should be as simple as

sessionStorage.getItem("emp-key")

Is it possible to load a variable from a JS script in another HTML file?

I can think of two easy ways.

1.) Try out sessionStorage: sessionStorage.setItem('key', variable); will store the variable value in the browser session storage. sessionStorage.getItem('key'); will return the set value of said variable.

See: https://developer.mozilla.org/de/docs/Web/API/Window/sessionStorage

2.) Add the variable value to your url www.yourdomain.com?key=value and retrieve it from your second script.

const urlString = window.location.href;
const url = new URL(urlString);
const value = url.searchParams.get("key");

See: How to get the value from the GET parameters?

Implement session storage in an Angular 8 application

For saving values while refreshing the page, you can use the localStorage or the sessionStorage for that. There is no external library or import necessary. It should work out of the box in most of the browsers.

For saving:

// clicks is the variable containing your value to save
localStorage.setItem('clickCounter', clicks);
// If you want to use the sessionStorage
// sessionStorage.setItem('clickCounter', clicks);

For loading:

const clicks = localStorage.getItem('clickCounter');
// If you want to use the sessionStorage
// const clicks = sessionStorage.getItem('clickCounter');

You can check this in Chrome using the dev tools.

How to store session data inside sessionStorage after invoking an API using PHP?

To use the SessionStorage on the browser you must use javascript that is a language executed on the client side (browser), php is a language that is going to be executed on the server side, so is not valid to do what you need.

To fix your example you can:

1. Use php to call the API and send the result to the client assigned to one variable, so it can be read from javascript ans stored in the SessionStorage.
2. Use javascript to perform the call to the API, using this way you are going to have less performance problems in the future.

I also recommend you to read something about client side/server side differences as was pointed by @jon-stirling.

Using your code, one example for case 1 could be:

$url_get_fc = 'http://apiurlhere'; 

//Send the request
$response_fc = curl_exec($ch_fc);
curl_close($ch_fc);

//Check for errors
if($response_fc === FALSE){
 die(curl_error($ch_fc));
}
// Decode the response
$responseData_fc = json_decode($response_fc, TRUE);

// sessionStorage

echo '
<html><head>
<script type="text/javascript">
    alert("'.$responseData_fc.'");
</script>
</head><body></body></html>';
