PHP Switch Statement

If you want to select one of many blocks of code to be executed, use the Switch statement.

The switch statement is used to avoid long blocks of if..elseif..else code.

switch (expression)
case label1:
code to be executed if expression = label1;
case label2:
code to be executed if expression = label2;
code to be executed if expression is different from both label1 and label2;
This is how it works

A single expression (most often a variable) is evaluated once.

The value of the expression is compared with the values for each case in the structure.

If there is a match, the code associated with that case is executed.

After a code is executed, break is used to stop the code from running into the next case.

The default statement is used if none of the cases are true.

switch ($x)
case 1:
echo "Number 1";
case 2:
echo "Number 2";
case 3:
echo "Number 3";
echo "No number between 1 and 3";
