A brief analysis of the specific meaning of PHP object_PHP tutorial

Everyone knowsPHP object initialization: To initialize an object, use the new statement to instantiate the object into a variable.

1. < ?php
2. class foo
3. {
4. function do_foo()
5. {
6. echo "Doing foo.";
7. $bar
8. = new
9. foo;
10. $bar->do_foo(); ?>
11. Convert to PHP object: If you convert an object to an object, it will not change anything. If a value of any other type is converted to an object, an instance of the built-in class stdClass will be created. If the value is NULL, the new instance is empty. For any other value, the member variable named scalar will contain the value.
