No. (well, yes you could, but it makes little sense as general approach) Sample code to serialize a zval: #include "ext/standard/smart_str.h" #include "ext/standard/php_var.h" zval *data; /* data to be serialized */ php_serialize_data_t var_hash; /* temporary data */ smart_str buf = {0}; /* result will be stored in there */ PHP_VAR_SERIALIZE_INIT(var_hash); php_var_serialize(&buf, &data, &var_hash TSRMLS_CC); PHP_VAR_SERIALIZE_DESTROY(var_hash); buf.c then has the data as char*, buf.len the length. In case of a problem buf.c will be NULL. The var_hash thing is needed as the serializer supports serializing different related zvals in sequence. (This was needed for sessions and register_globals ...) Serializing looks like that: unsigned char *data; /* serialized data */ int data_len; /* length of the serialized data */ php_unserialize_data_t var_hash; PHP_VAR_UNSERIALIZE_INIT(var_hash); if (!php_var_unserialize(&return_value, &data, data + data_len, &var_hash TSRMLS_CC)) { PHP_VAR_UNSERIALIZE_DESTROY(var_hash); /* error handling */ } else { PHP_VAR_UNSERIALIZE_DESTROY(var_hash); /* success, return_value is filled */ } You can also check the implementation of (un)serialize in ext/standard, this was from some other code I had at hand right now. hope it helps johannes
