Please review someone more initiated in PHP, PDO code.
This fix an old frustrating bug in blob param binding.
Also include proper handling when NULL is passed.

case SQL_BLOB:
case SQL_BLOB: {
if (Z_TYPE_P(parameter) == IS_NULL) {
// Check if this field allow NULL values

Anatol, please close also #61895.
It is also related to this fix. Stack trace show that engine hangs on param_dtor.
I examined db metadata / php script and they have blob fields and parameters: TB_NIOKR / ACOMMENT DOM_TEXT.
