- PHP 배열과 키 값
<!DOCTYPE html>
<html>
<body>
<?php
$age=array("Peter"=>"35","Ben"=>"37","Joe"=>"43");
echo "Peter is " . $age['Peter'] . " years old.";
?>
</body>
</html>
(예제 출처: PHP Arrays)
(실행 결과)
Peter is 35 years old.
(같은 결과 다른 소스)
<!DOCTYPE html>
<html>
<body>
<?php
$age['Peter']="35";
$age['Ben']="37";
$age['Joe']="43";
echo "Peter is " . $age['Peter'] . " years old.";
?>
</body>
</html>
- PHP 배열과 키 값 그리고 반복문
<!DOCTYPE html>
<html>
<body>
<?php
$age=array("Peter"=>"35","Ben"=>"37","Joe"=>"43");
foreach($age as $x=>$x_value)
{
echo "Key=" . $x . ", Value=" . $x_value;
echo "<br>";
}
?>
</body>
</html>
(예제 출처: PHP Arrays)
(실행 결과)
Key=Peter, Value=35
Key=Ben, Value=37
Key=Joe, Value=43
- PHP 다차원 배열
<!DOCTYPE html>
<html>
<body>
<?php
// A two-dimensional array
$cars = array
(
array("Volvo",100,96),
array("BMW",60,59),
array("Toyota",110,100)
);
echo $cars[0][0].": Ordered: ".$cars[0][1].". Sold: ".$cars[0][2]."<br>";
echo $cars[1][0].": Ordered: ".$cars[1][1].". Sold: ".$cars[1][2]."<br>";
echo $cars[2][0].": Ordered: ".$cars[2][1].". Sold: ".$cars[2][2]."<br>";
?>
</body>
</html>
(예제 출처: PHP Multidimensional Arrays)
(실행 결과)
