My basic skills are not solid, so I have to try classes, subclasses, inheritance, virtual, abstract, and override today. Rule 1: override a function with the same name as the parent class to use new, and override to override the function.RelatedCode:Class{Public void AAA (){}} Class B:{Public void AAA (){}}Error message: the keyword new is required on "B. AAA

/xxx/xxx/xxx/xxx/ "), then the path in front of our code can be omitted. 1 php 2 set_include_path ("xxx/xxx/xxx/xxx/xxx /xxx/xxx/xxx/xxx/xxx/xxx/" 3 include ("test1.php" 4 include ("test2.php" 5 include ("test3.php" 6 require ("test4.php" 7 require ("test5.php" 8 ? The Set_include_path function can also set multiple path variables to be used under Linux: Delimited, under windows, and delimited. Like what:1PHP2 Define(' A ', ' xxx/xxx/xxx/xxx/xxx/xxx/xxx/xxx/');3 Define(' B ',

common backdoor method (although the method is very retarded ......).There is another interesting thing about the full name: create an account zzz using the net user, change the password zzz to zxc in the user account. After that, I created a new account named zxc with the password zxc, and logged out. It was speechless:1. Username zzz and password

The order has the following altogether:(1) Enable secretEnable secret 0 password plaintextEnable secret 5 cipher cipher (MD5 encryption)(2) Enable passwordEnable password 0 password plaintextEnable password 7 cipher cipher (CISCO private algorithm encryption)Note: Parameter 0 can also not writeUsage:(1) Enable secretAfter you execute the Enable secret 0 zzz command, you can log in using the password zzzHowever, after you execute the Enable secret 5zzz

makefile or modify the path variable definition to see what happens. 5.2.3 prevents environment variables from being overwritten You can use the-e option to prevent an environment variable from being overwritten with a variable of the same name, such as the-e option: Make-f ENVI.MK-E Terminal printing: Def 5.2.4 command line variable Unlike environment variables, the command-line variables specified when you execute make will overwrite the definition of a variable with the same name in mak
