Re: Safely upload a file 9 Hours Ago by Dani I realize I could have done better when coming up with a safe name. As it stands, a file uploaded that has a file name in non-Latin characters will just end up with a bunch of underscores. I’m not even sure if that suffices as a file name, but for sure there will be collisions as multiple files are attempting to be saved with the same _ name.

Dynamic Properties in PHP 8.2 6 Days Ago by Dani In my increasingly futile attempt to remain using the now-defunct CodeIgniter 3 framework, I came across something that I figure might be worth sharing in case anyone else is maintaining older PHP codebases and suddenly things start breaking after a PHP upgrade. With PHP 8.2, there’s a new warning that’s catching a lot of people off guard: … Re: Dynamic Properties in PHP 8.2 6 Days Ago by Dani Oh, and an important bit I forgot to mention: PHP's built-in stdClass has the `#[AllowDynamicProperties]` attribute already added. In fact, you can see in the [PHP docs](https://www.php.net/manual/en/class.stdclass.php) that the definition of the stdClass is "a generic empty class with dynamic properties." That means that you can always … Re: Dynamic Properties in PHP 8.2 2 Days Ago by Dani The first I agree would not make much sense to do because one would presume that the User class has its own set of getters and setters for a reason, and just creating random properties on a whim defeats the purpose of organizing and structuring your code by having the class in the first place. Nevertheless, I ran into this exact issue while trying … Re: Dynamic Properties in PHP 8.2 3 Days Ago by jkon I can't get it , why anyone would want to `$user = new User(); $user->nickname = 'Dani';` if nickname is not a public property of User , or even worse `$user = new stdClass(); $user->nickname = 'Dani';` ? Why ? Re: Dynamic Properties in PHP 8.2 2 Days Ago by Dani > This obviously does not make sense to do if you want to create or work with a User object or something of that sort. I realize that in my previous post I incorrectly gave the example of `$user = new stdClass(); $user->nickname = 'Dani';`. My intention was not to say that it was good coding practice to represent a user of the app with an … Safely upload a file 1 Day Ago by Dani Here's a quick bit of code to upload a file in PHP. Re: How to show visa info based on country selection in a travel form? 1 Day Ago by Biiim I felt like some fun, so I just put together an example for you using CDN's and bootstrap 5. From what you are talking about you probably want to put some of that logic into the Javascript and not need to send a server request for each one, I usually do this kind of thing with javascript objects/arrays (eg `settings['GB']['visa_req'] = false;… Re: How to show visa info based on country selection in a travel form? 6 Days Ago by groverharleen Hello, please use developer tool while working on HTML/PHP with AJAX. in the console you can easily track what was the POST/GET request made to PHP file and what is the responses shared by PHP file. try debugging response accordingly or if still you face any trouble, please do share screen shot of Header / Request / Response Tabs. i'll … Re: My php is showing wrong results of time difference 3 Weeks Ago by Dani I am confused when you say the HTML time picker input box can be set to 20:00 for time in and 5:00 for time out, because `<input type="time" ...>` only allows the end-user to specify a time, not a time and date combination. Should it always be assumed that if the time out is earlier than the time in, that it is the next day? … Re: My php is showing wrong results of time difference 3 Weeks Ago by Dani In other words, if you just need days or hours you can do something like `$diff->d` or `$diff->h` (All properties available [here](https://www.php.net/manual/en/class.dateinterval.php), but if you want to calculate a runner's start time and end time and then do something like "You ran the race in 08:33:56!" then you could use the `… Re: How to connect to the Pinterest API using PHP? 2 Weeks Ago by geekinformatic Hey!

Re: How do I remove the last character without breaking the string? 2 Weeks Ago by MAY_261 Use mb_substr() instead of substr(). It handles multibyte characters and emojis correctly.

That ensures that when you pull up a topic, we can retrieve all items for that topic in one request, all from one server.
