You can add three modifiers to the members (properties, methods, class constants) in the class for permission access.

The location where access is requested can be divided into:

  1. Internal of a certain class
  2. Internal of a parent/child class with inheritance relationship
  3. External of a certain class

public public, shared, public {1, 2, 3}

  • Accessible from anywhere

protected The {1}

  • cannot access the private members of the parent class on a protected basis
').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i

').text(i)); }; $numbering.fadeIn(1700); }); });

The above introduces the access modifiers of PHP, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
