Registering and running own debug function in Symfony

I am developing a web app using Symfony 5.4 and my current goal is to define and run a function

function setTestDate(): void
{
    testdate = $_REQUEST['testdate'] ?? null;
    if ((int)$_SERVER['APP_DEBUG'] && $testdate !== null) {
        CarbonCarbon::setTestNow($testdate);  //  provided by Carbon, a real life-saver
    }
}

as early as possible, already before the Authenticators are called. I previously tried to run this during the event ‘kernel.request’ but this was already too late in the event flow: My authenticator checks the age of a certain token and without a fixed testdate my fixtures would have to be updated all the time.

I know of many bad places to insert this into (index.php, the Authenticator itself, etc), but does anybody know of a “clean” way to call that function, maybe during SymfonyComponentErrorHandlerDebug::enable()? It seems like none of the built-in events are that early and I’d hate to edit index.php. I am aware of onVoterVote(), but this testdate should be used even if no Authenticator was called.

I guess this looks like I’m over-engineering a minor problem, but I am continuously trying to improve my coding style.

Is there a way to restart reset Opcache periodically or invalidate not accessed files

I’m currently using Plesk for a shared hosting server, this allows me to give every website it’s own PHP-FPM handler. This also means that every website has it’s own seperate Opcache.

The issue with this is that every site can fill it’s own cache.
Let’s say there are 10 sites with 64 MB for Opcache, that’s 640 MB in total!
Lot’s of those sites don’t get visited regularly, so the cache could be cleared after a while.

A solution could be to restart the PHP-FPM process for every site, but this will result in errors for visitors.
Another solution would be 1 PHP-FPM handler, but the cache will get filled by the big sites.
This results in automatic Opcache restarts because the memory is full.

My question: is there a way to reset the cache periodically, or is there a way to clear the files from the cache when they haven’t been access for let’s say a week?

Uncaught Error: Non-static method Database::query() cannot be called statically [duplicate]

I am trying to execute a database query but I am getting this error. I am very frustrated.

class Database {
  //verbind met onze database
  private $host = DB_HOST; //server naam - normaal localhost
  private $dbName = DB_NAME; // Naam van de database
  private $username = DB_USER; //Pas aan als dit nodig is
  private $password = DB_PASS; //In xamppp is dit normaal leeg maar pas aan als dit nodig is.
  private $pdo;
  public $lastInsertId;
  
  function __construct() {
    $this->startConnection();
  }

 function startConnection() {
    $this->pdo = new PDO("mysql:host=".$this->host.";dbname=".$this->dbName,$this->username,$this->password); //Gebruik de variables die we eerder hebben ge-set
  }

  public function endConnection(){
    $this->pdo = null;
  }


  
  public function query($query, $params = array()) {
        $statement = $this->pdo->prepare($query);
        $statement->execute($params);
        if (explode(' ', $query)[0] == 'SELECT') {
        $data = $statement->fetchAll();
        return $data;
        }
    }

  public function lastID($query, $params = array()){
    $stmt = $this->pdo->prepare($query);
    $stmt->execute($params);
    $ID = $this->pdo->lastInsertId();
    $this->lastInsertId = $this->pdo->lastInsertId();
    return $ID;
  }

This is my database class. I of course handle my database stuff here

This is where I get my error from, this is from another page and it says: Fatal error: Uncaught Error: Non-static method Database::query() cannot be called statically in C:xampphtdocsExcellentTasteviewsReservations.php:7 Stack trace: #0

$reservations = Database::query("SELECT * from reserveringen");

PHP: Warn on undefined array write

Let’s preface this with an example of a script with typo:

$bc = getBaseConcept();
$bs['key'] = doOtherStuff($bc['key']);
return $bc;

Obviously in the middle line is a typo. It should be $bc instead of $bs. (And yes this was a legit typo of mine just minutes ago before writing this question)

This did not produce a warning.
So my question is: Is there a configuration option that lets this produce a warning?

Specifically: Writing to an array key of a name that was previously undefined.

E_ALL does not seem to help. This should not only generate the warnings for $bar but I want also a warning for $foo.

<?php 
ini_set('error_reporting', E_ALL);
echo ini_get('error_reporting'), "n";
$foo['bar'] = $bar['foo'];

Why css files working in local laravel but not in heroku?

I have Laravel app.

I am referencing a CSS file.

The file is inside a public folder, css app.

it is working fine locally when deploying to heroku, it says 404.

web: vendor/bin/heroku-php-apache2 public/

and my .htcsss

is

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteCond %{REQUEST_URI} !^public
    RewriteRule ^(.*)$ public/index.php?$1 [END,QSA]
</IfModule>

both in the root and under public folder.

How can I create m3u8 file and ts files from the uploaded mp4 by php?

I have a php web application (Using code igniter).
I want to build such features.

  1. User upload the mp4 file to the admin dashboard.
  2. On the backend (PHP), we convert the mp4 file to m3u8 and ts files.
  3. The backend save the m3u8 and ts files on the digitalocean’s Spaces.
  4. On the client side, we use “hls.js” to show the video.

I think I need to use PHP-FFMpeg, but I am not quite sure how to make it.

PHPUnit – assertCount() not returning same result

I am using assertCount() method within my Symfony project and PHPUnit Functional tests. I was refactoring a method, and suddenly I does not work any more. But I am not sure what could be a problem.

I wanted to move my method that I am using multiple times from one class:

public function testPostSuccessful(): void
{
    ... 
    // rest of the request code //

    $response = $this->client->getResponse();
    $responseBody = json_decode($response->getContent(), true);

    $this->assertArraySimilar($this->expected, $responseBody["data"][0]);

    $this->assertEquals(200, $response->getStatusCode());
}

And in my other method:

protected function assertArraySimilar(array $expected, array $array)
{
    // expected amount of key - value pairs are returned
    $this->assertCount(6, $array);
    
    ...
    // rest of the code //
}

This is throwing an error:

Failed asserting that actual size 2 matches expected size 6.

But when I dump the result like:

var_dump(count($array));die;

I get: int(6)

What could be the problem here?

Problem with fetching value out of foreach loop in php

I am having trouble fetching values from foreach loop. I always get NULL values when I try to send request in postman. Here is my code and what I have tried.

php code

$symbol = $request->symbol;
$ticker = $api->prices();

foreach ($symbol as $ticker => $pairname)
{
    echo $pairname;
}

in postman I send request like this

{
   "symbol":"BTCUSDT"
}

When I var_dump $ticker variable the response I get is as follows

array(147) {
["XRPBUSD"]=>
string(6) "0.5881"
["MKRUSDT"]=>
string(7) "2003.70"
["SRMUSDT"]=>
string(6) "2.2300"
["BTCUSDT"]=>
string(6) "37173.34" ... } and etc.

I need when I send symbol value in postman that it prints that value in foreach loop from that $ticker variable. Currently I get NULL value.

Woocommerce Payment Callback not returning the receipt page after successfull transaction

One php5.6 page doesn’t display well

I’ve got a task to put a website written in php 5.6 on a server. I used Centos 7, Apache and Mariadb. The site displays correctly but one of the pages shows only half way through no matter what I try.
So, the same page exists in a different language: the exact same code, the exact same css and js files are imported and apache shows exact same warnings about a few unidentified variables – but it shows that on every single working page because of the old php 5.6 and 5.5 functions (my guess).

Has anyone experienced anything similar?

Do I need a different server or additional php libraries?
I followed this guide https://computingforgeeks.com/how-to-install-php-on-centos-fedora/ for installing old php.

It is a bit vague, but I have to start from somewhere.

Thank you!
