PHP Control Structures

PHP control structures owned similar to other programming languages​​.
    There are 2 types of control structures, namely:
1. branching structure
2. Structural repetition

A. Branching structure
     Is a command that allows the selection of the command to be executed in accordance with certain conditions.

3 orders of branching in PHP:

a. IF
    Used to run one or more commands before checking with many given conditions, if the condition is true       then a series of statements will be made, if the condition is false then the statement will be executed for the wrong condition.

b. IF ... ELSE
     A command similar to the previous command, but the command block is used to many different conditions

c. SWITCH
      Alternative command structure for a replacement IF .. ELSE with else rather than one that makes the program easier to understand.

B. Repetition structure

     Used to repeat a command. There are 3 kinds of loop in PHP, namely:

a. FOR, used to repeat the order with a known number of repetitions.
 
b. While, used to repeat a command to a certain amount. Having a final value true or false and the loop will    continue as long as the condition is true.

c. Do ... While, almost as denagn while but looping commands will be done first and will stop when it stops search certain conditions.
