Possible disadvantages of PHP

  • Error Handling
    Error handling in PHP is less efficient and more cumbersome compared to modern languages like Python or JavaScript.

  • Old Codebases
    Many older PHP applications use outdated coding practices, making maintaining and updating them more difficult and costly.

  • PHP's Biggest Problem
    The PHP website is indeed one of the worst parts of the whole ecosystem. Just look at the landingpage (https://php.net) and compare it with those of other languages. There's not a single piece of PHP code on the page. No "what is PHP", no "why should I use it", and no "that's why PHP is great". It's just a news page showing the latest releases, and a small section for downloading PHP. And speaking of the website:... - Source: Hacker News / 2 months ago

Vigilant is written in PHP using the Laravel framework, for queuing it uses Laravel Horizon. This is a queuing system built on top of Redis. All monitoring tasks in Vigilant are executed on this queue, it allows for multiple queues... - Source: dev.to / 8 months ago
  • The Lost Art of Reading Documentation
    I remember being 15 (18 years ago ๐Ÿฅฒ) and learning PHP. Stack Overflow wasnโ€™t as big yet, and finding answers often meant digging through forums filled with half-baked solutions, each dependent on specific hosting configurations. There was no universal standard, some hosts supported certain php.ini settings while others didnโ€™t. The only reliable resource? The official PHP documentation: php.net. - Source: dev.to / over 1 year ago
  • Using named arguments in php8 and up
    That's the first I've heard of it, and I like it! I can't tell you the number of trips to php.net to look at argument order for a function. Is it haystack/needle, or needle/haystack? Of course it could turn into the same thing w/ argument names (is it whole_name or full_name?), but I'm going to use it. Source: about 3 years ago
