PHP Control Structure
control structure :-
Determine the flow of control in program.
there are four types of control structurs. they are
1. sequence c.s :-
are executed in the same order in which they appear in the program.
2.selection or decision control s :-
allow the computer to take a decision as which instruction or control is to be executed next.
3.Repitition or loop c.s :-
to execute the group of statements repeatedly.
4. case c.s :-
allow the computer to take a case as which instruction or control is to be executed next.
OR
PHP Control Structure:-
1. Conditional Control Structure
2. Iterative Control Structure
Sno This Expression Meaning
1 x==y x is equal to y
2 !x=y x is not equal to y
3 x<y x is less than y
4 x>y x is greater than y
5 x<=y x is less than or equal to y
6 x>=y x is greater than or equal to y

$b=$a-$b; // $b=$a/$b;
$a=$a-$b; // $a=$a/$b;
echo ” after swapping variables ”
echo $a;
echo $b;
