After 20+ years working with PHP, I am still discovering useful and/or funny things about it!
- You can insert an exclamation into the
DateTime::createFromFormat()method call to reset all of the remaining time units.
// 2021-10-12 21:48:07.0 DateTime::createFromFormat('Y-m-d', '2021-10-12'); // 2021-10-12 00:00:00.0 DateTime::createFromFormat('!Y-m-d', '2021-10-12');
- You can increment ASCII strings with
$x = 'a'; $x++;// $x is now 'b' $x = 'ab'; $x++;// ac $x = 'zz'; $x++;// aaa $x = 'ы';// cyrillic 'y', unicode $x++;// ы (remains the same)
I think this is a horrible feature, and a very inconsistent one. Decrement doesn’t work, and neither does
echo $x + 1;, after
$x = '1'; $x++;$x is no longer a string but int. Overall it looks like a totally bad idea to rely on this feature. But, hail to BC, it’s still here in PHP 8.
