Edit report at https://bugs.php.net/bug.php?id=67782&edit=1 ID: 67782 Updated by: stas@php.net Reported by: joelm@php.net Summary: Internal Cursors Status: Open Type: Bug Package: PHP Language Specification -PHP Version: Irrelevant +PHP Version: PHP-5.6 Block user comment: N Private report: N New Comment: I'm not sure this has a place in the spec, as this is largely an implementation detail, also one that changes somewhat between 5.6 and 7. Previous Comments: ------------------------------------------------------------------------ [2014-08-05 17:11:59] joelm@php.net Description: ------------ https://github.com/php/php-langspec/blob/master/spec/12-arrays.md#arrays The concept of an array's internal cursor or an object's internal cursor is never mentioned. The state of the internal cursor of an array or object can be witnessed via the current(), key(), next(), prev(), reset(), end(), and each() library functions. While it's technically library functions that expose the state of the cursor to the programmer, you can find code deep in the core array/object implementation of PHP5 that deals with and maintains internal cursors. Also, internal cursors get mentioned in various parts of the php.net documentation, including the documentation for "foreach", so internal cursors are arguably a language feature. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67782&edit=1
