• Facebook API: photos only getting some tagged photos and no videos

  To start with, my Facebook app is still in development and has not gone through the review yet.

  I have a PHP script which grabs all photos but it's only grabbing some of the tagged photos.

  It's also not grabbing any videos from my Facebook profile even though I'm only grabbing my own data as an admin test user in the app.

  Here is my code to instantiate the Facebook API:

  $this->fb = new Facebook([
      "app_id"                => $this->fbAppId,
      "app_secret"            => $this->fbAppSecret,
      "default_graph_version" => "v2.7",
  ]);
  

  Here is my API call:

  $userRawData = $this->fb->get("/me?fields=feed{message,attachments,created_time},name,videos,photos{created_time,id,images},albums{name,photos{created_time,id,images}}", $this->fbAccessToken);
  
• Class 'PDF' not found - Laravel 5.4

  I am trying to generate a PDF report in my application using the barryvdh/laravel-dompdf package, but I'm receiving an error:

  Class 'PDF' not found

  I have followed steps from previous answers to similar questions, but they don't seem to help me.

  I added the following lines in my composer.json file:

  "barryvdh/laravel-dompdf": "^0.8.0",
  "dompdf/dompdf": "0.8.0 as 0.6.2"
  

  Then, I ran composer update. Afterwards, I included the following lines in my config/app.php:

  Barryvdh\DomPDF\ServiceProvider::class,
  'PDF' => Barryvdh\DomPDF\Facade::class,
  

  And finally, I ran the following commands in my terminal:

  php artisan cache:clear
  php artisan config:cache
  

  Controller

  Use PDF;
  
  $pdf = PDF::loadView('app.feestdreportprint',compact('datas','rdata','stdinfo','institute'));
          return $pdf->stream('student-Payments.pdf');
  

  But I am still getting the same error. What can I do to solve this issue? My laravel version is 5.4.
• Routing with Json file

  I make a website site in PHP with the MVC model and I want to choose the name of each route. Therefore my URLs are not like this website.com/controller/function/params.

  My URLs in my JSON file look like this :

  {
    "homepage":{
      "url":"/",
      "controller":"HomeController",
      "function":"index",
      "title":"Homepage"
    },
    "user_profile":{
      "url":"/profile/{username}",
      "controller":"UserController",
      "function":"user_profile",
      "title":"User profile"
    }
  }
  

  When I go to the website, my Application.php load the JSON file to do a foreach to search if url exist. In this loop, I use the function preg_match to know if the URL match with the url of the JSON file.

  The problem is that with the foreach, each page load can be very slow if the site contains a lot of pages. But I can't use the key of my JSON file because some pages have one or more parameters (example: website.com/profile/toto).

  How can I solve this problem by keeping 100% custom URLs without loop?
• How can I add optional validation patten in preg_match?

  I'm try to use preg_match to parse the line. But, couldn't get the result correctly.

  I want to parse those lines with optional // char.

  Basic idea is some lines may contain //0016OIXXXXXXX (//4 digit and 9 str) and some line may not contain (//4 digit and 9 str).

  Next line \n is mandatory.

  Here are some sample lines;

  Line 1

  1812121212DD2220,31NTRFNONREF 502?102330

  Line 2

  1811091109CD20693,12NTRFRMSOIC110871941//0016RFXXXXXXX 206?000801

  Here is my patten;

  /(\d{6})((\d{2})(\d{2}))?(C|D)([A-Z]?)([0-9,]{1,15})([A-Z]{1,4})([A-Z a-z 0-9]{1,16})(\/\/)([0-9A-Z]{1,16})(\s*\n)([0-9]{1,3})(\?)([0-9]{0,6})/

  Current patten can only work with //. If without //, patten is broken and can't parse the line.

  I don't know how should I add (\/\/)([0-9A-Z]{1,16}) as optional patten.

  Thanks in advance :)
• PHP Check if a string has at least two specific words in it

  I'm using preg_match to check if a string has a specific word in it:

  $string = 'This string contains a few words that are in an array!';
  $arr = ['string', 'few', 'words'];
  
  if(preg_match('['.implode('|', $arr).']', $string)){
      //do something if there is at least one word from the array inside that string
  }
  

  This is working quite nice but it will return true if there is at least one word and i need it to return true if there are at least two words from the array inside that string.

  Can that be done in one step? If not, which way should i go from here to obtain that result?

  Thank you!:D
• converting command from ereg

  I'm struggling to convert a command from ereg to preg_match. This is the command:

  ereg("([0-9]+)[ \t]+(.+)[ \t]*$", $data, $regs);

  I was expecting to use :

  preg_match("/([0-9]+)[ \t]+(.+)[ \t]*$/", $data, $regs);
  

  But the results of $regs is wrong. Can anyone advise the best way to do this and why the above is wrong ?

  Thanks
