Flow-Control Statements

49
A
switch
statement is given an expression and compares its value to all cases in the
switch; all statements in a matching case are executed, up to the first
break
keyword
it finds. If none match, and a
default
is given, all statements following the
default
keyword are executed, up to the first
break
keyword encountered.
For example, suppose you have the following:
if ($name == 'ktatroe')
// do something
elseif ($name == 'rasmus')
// do something
elseif ($name == 'ricm')
// do something
elseif ($name == 'bobk')
// do something
You can replace that statement with the following
switch
statement:
switch($name) {
case 'ktatroe':
// do something
break;
case 'rasmus':
// do something
break;
case 'ricm':
// do something
break;
case 'bobk':
// do something
break;
}
The alternative syntax for this is:
switch($name):
case 'ktatroe':
// do something
break;
case 'rasmus':
// do something
break;
case 'ricm':
// do something
break;
case 'bobk':
// do something
break;
endswitch;
Because statements are executed from the matching case label to the next
break
key-
word, you can combine several cases in a
fall-through
. In the following example,
“yes” is printed when
$name
is equal to “sylvie” or to “bruno”:
switch ($name) {
case 'sylvie': // fall-through
