Title, I'm a little confused, who can say it carefully:
1, the difference between psr-0 and psr-4 in composer;
2, the difference between the psr-0 norm and the psr-4 norm;
3, composer and Php-fig, who indulge who.

PHP-generated CSV can sometimes encounter two special cases:
1, the output of the field, contains an extra long number (18 digits) such as ID: 122121197410180016, even if the output field with "", or will be recognized as a number, and loss of precision, the back of the 4 will become 0, like this look 122121197410180000
2. In the output field, a numeric string containing leading

char * c. c In char c [0] is not a pointer but an offset, this offset points to the space next to a and B, so it does not actually occupy any space. Tag4 adds this point. Therefore, if the last member of the struct pppoe_tag above is defined using char * tag_data, it will not be used unless it occupies four more byte pointer variables:Method 1: during creation, you can first allocate a memory for struct pppoe_tag and then allocate the memory for tag_
