This example describes how to traverse all elements in the php class. Share it with you for your reference. The specific analysis is as follows:

All elements in the php class can be output as key-value.

Class MyTestClass {const TESTVAR1 = 1001; const TESTVAR2 = 1002; const TESTSTR1 = 'hello';} $ rc = new ReflectionClass ('mytestclass '); $ v = $ rc-> getConstants (); asort ($ v); // sort by value // ksort ($ v ); // sort by keyforeach ($ v as $ name = >$ value) {echo "$ name = >$ value \ n ";}
