🚨 Massive surge in automated #botnet activity
→ Targeting PHP servers, IoT devices & cloud gateways
→ Mirai, Gafgyt, Mozi exploiting known CVEs
→ AWS & Google Cloud used to hide source
Experts warn: even low-skilled attackers can now wreak havoc with public exploit kits.

The keyword “final” for #PHP classes offers many reasons for discussion. There may be valid use cases, and there are other cases where it makes other people's work more difficult.
Dear #TYPO3 extension developers, what's the reason for marking a service class with “final” and not adding a single PSR-14 event? It's great that you've made your extension public. But suddenly I'm stuck in a dead end that you've put me in for no reason, just because it seems to be trendy to mark classes as “final” 🙄

I love you #FreshRSS but wow is there one feature I wish existed and would turbocharge my ability to read and keep up on #RSS...
Please add grouping by day...
Opened a Feature Request issue for it https://github.com/FreshRSS/FreshRSS/issues/8168
(Also hey if any #PHP wizards wanna contribute and take this one on... I'd love you!).
(Some basic grouping is already done so I can't imagine why this couldn’t ostensibly be extended a tiny bit further...)

Ever wondered whether it's faster to directly cast a variable versus invoke a casting function in PHP?
I wondered, so I wrote a script that calls (bool) $int 1000 times, then invokes boolval($int) 1000 times. It turns out that boolval() is between 15% and 250% faster than an explicit cast.
I'll bet the same is true for intval(), floatval(), and strval().
(There may be weird PHP optimizations going on, so this is not necessarily scientific.)

#php #ai болваны разочаровывают. Писал задачу про безопасность - есть в проекте CVE. Мало того, что нужно в проекте повысить версии пакетов в composer.lock что-бы убрать CVE. Надо еще обновить compose.json что бы версии были не ниже текущих исправленных. 3 ai вообще теряются как джуны на собеседованиях. А я точно помню, что я такое слышал на конфе... толи от Александра Макарова (yii), возможно от Валентина Удальцова.... короче главные по php тусе.
Ожидаешь от ai более широкого кругозора, что он все помнит. А вот нифига.
