I'm strongly opposed to adding any flags to is_array - keeping basic type checks simple would help in learning/reading/remembering the language, has a small impact on performance for calls that aren't unambiguously qualified (especially if using both), and it makes it harder to see issues like `is_array(really_long_multiline_call(arg1, arg2, ZERO_INDEXED))` An idea for a PECL would be `pecl_check_type($value, PREFIX_MAY_BE_ARRAY|PREFIX_MAY_BE_ARRAY_KEY_LONG|PREFIX_MAY_BE_ARRAY_OF_STRING|PREFIX_MAY_BE_ARRAY_OF_OBJECT)` to check for an array with integer keys and strings and objects as values, but I really can't imagine it getting adopted or being the main performance bottleneck in a typical php application, especially with the jit and with most arrays being small. (I don't have any interest in actually doing that) Cheers, Tyson -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
