I believe it is just a naming issue. Not even sure that PHP devs have agreed on how to name the type. Internally, PHP calls them both arrays and hash tables if I understand correctly. In Zend/zend_types.h[1] of PHP source: typedef struct _zend_array zend_array;
typedef struct _zend_array HashTable;
struct _zend_array {
...
};
That being said AFAICT, HashTable and zend_array are used interchangeably throughout the source. I am not a C programmer, but I did write a couple of PHP extensions and that was my general understanding. Perhaps it is a compatibility issue or just used to abstract types differently in various areas of the C API.Check out [2] for a deeper understanding of how arrays are handled internally in PHP.
