php多分支语句,PHP中的分支及循环语句

这次实践的都是PHP7的语法。

感觉是以前的5差别不是那么大，只是希望越来越快吧。

$looking = isset($_GET['title']) || isset($_GET['author'])

?>

BookStore

echo "Befor the conditional.
";

if (2 > 2) {

echo "Inside the conditional.
";

} elseif ( 2 == 2) {

echo "Print when 2 == 2.
";

} elseif ( 2 < 2) {

echo "Not evaluted.
";

} else {

echo "Inside the else.
";

}

echo "After the conditional.
";

$title = 'Harry Potter';

switch ($title) {

case 'Harry Potter':

echo 'Nice story. a bit too long.';

break;

case 'Load of the Rings':

echo 'A classic!';

break;

default:

echo 'Dunno that one.';

break;

}

echo "
";

$i = 1;

while ($i < 4) {

echo $i . "
";

$i++;

}

echo "
";

$i = 1;

do {

echo $i . "
";

$i++;

} while ($i < 0);

for ($i = 1; $i < 10; $i++) {

echo $i . "
";

}

$names = ['Harry', 'Ron', 'Hermione'];

for ($i = 0; $i < count($names); $i++) {

echo $names[$i] . "
";

}

foreach ($names as $name) {

echo $name . "
";

}

foreach ($names as $key => $name) {

echo $key . ' -> ' . $name . "
";

}

?>

输出：

Befor the conditional.

Print when 2 == 2.

After the conditional.

Nice story. a bit too long.
