What is the size of a bool in PHP?
For an int, it's easy to determine
echo PHP_INT_SIZE;
I got 4 so 8 bytes or 32 bits. What about for a bool type? Thanks.
回答1:
The size of a bool can be found by looking at the php source directory Zend/zend_types.h:
typedef unsigned char zend_bool;
With the size of unsigned char being 1 byte.
