If you do not name more >than one element, this means that some data is overwritten as the keys are the same such as in: It is not correct that an empty string is used. The index 1 is used. var_dump(unpack('V', 'abcd')); array(1) { [1]=> int(1684234849) } (It could not be inferred that the documentation means an empty string with "1" appended, because the number is not appended to a lone entry's name:) var_dump(unpack('Vname', 'abcd')); array(1) { ["name"]=> int(1684234849) } Here's a clearer way to write it: >If you do not name an element, numeric indices starting from 1 are used. Be aware that if you >have more than one unnamed element, some data is overwritten because the numbering restarts from 1 >for each element. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61169&edit=1
