3. Stack area: fast running, small size, saving basic types

4. Heap area: slow running speed, large submission, saving complex types

5. The process of instantiation is the process of allocating memory space

6. The object is saved in the heap area and the address of the heap area is saved to the stack area.

Analyze the code structure:

Class Student {public $name; public $sex; public function show () {echo 'man';}} $stu1 = new Student; / / allocate memory in the heap area, put the memory address in the stack area $stu2 = new Student; var_dump ($stu1); / / there are only attributes in the object variable, and there is no method $stu1- > show () / / Thank you for reading this article carefully.
