Arrays in PHP
Some notes about arrays in PHP over here: PHP: Frankenstein arrays. I was already aware of most of that but I thought the notes at the bottom about supporting JSON were handy:
If you want to enforce an array to encode to a JSON list (all array keys will be discarded), use:
json_encode(array_values($array));
And if you want to enforce an array to encode to a JSON object, use:
json_encode((object)$array);
Also array_is_list is available as of PHP 8.1.
PDOStatement::fetchAll()
I’m reading the source code for PDOStatement::fetchAll().
sizeof PHP data structures zval and zend_value
sizeof( zval ) == 16; sizeof( zend_value ) == 8;

The relevance of PHP
Seen today: Yes, PHP is Worth Learning/Using in $CURRENT_YEAR. There’s some good discussion on some of the more recent PHP language features and other notes about what’s available in the broader ecosystem.
Factory specialization
I just knocked this up to confirm my thinking was right:
<?php
class StdFeature {
}
class AppFeature extends StdFeature {
}
class FactoryBase {
public function new_feature() : StdFeature { return new StdFeature; }
}
class Factory extends FactoryBase {
public function new_feature() : AppFeature { return new AppFeature; }
}
$factory = new Factory();
$feature = $factory->new_feature();
assert( is_a( $feature, 'AppFeature' ) );
