actually, pval (defined in php.h) is only an alias of zval (defined in zend.h), which in turn refers to _zval_struct. this is a most interesting structure. _zval_struct is the "master" structure, containing the value structure, type, and reference information. the substructure zvalue_value is a union that contains the variable's contents. depending on the variable's type, you'll have to access different members of this union. for a description of both structures, see 표 32-2, 표 32-3 and 표 32-4.
