PHP 7.4 & MySQL: caching_sha2_password Denying long (20c) passwords

由 谁说我不能喝 提交于 2019-12-23 13:31:06
问题 UPDATE: I've found out which passwords are affected. See my answer below. An answer to why long passwords are rejected would still be much appreciated. Disclaimer: I have tried about 2 hours just setting different passwords. I am absolutely confident that the password below causes the issue. It works with other passwords. I do know how to fix it: use a different password. I want to know why it does not work. Because such inconsistency is not acceptable. I am able to reproduce the issue on my

Splatpacking versus array_values() to re-index an array with numeric keys

问题 As of PHP7.4, there is a newly available technique to re-index an array with numeric keys. I'll call it " array re-packing " or maybe something fun like " splatpacking ". The simple process involves using the splat operator ( ... ) -- aka "spread operator" -- to unpack an array then fills a new array with with the contents.

How to use arrow functions in PHP?

由 主宰稳场 提交于 2019-12-04 14:29:28
问题 I got to know about arrow functions in PHP 7.4. I tried using them like <?php $num = 1; $arrowfunction = () => { return $num + 1; } echo $arrowfunction(); Because I saw the => operator in the pull request. Just like javascript. I expected '2' as the output but this didn't work! I got Parse error: syntax error, unexpected ')' in /test.php on line 3 回答1: Arrow functions in PHP are introduced in PHP 7.4. They are a little different . The fn keyword The new fn keyword is now a reserved keyword.
