创建数组：
在 PHP 中， array() 函数用于创建数组
count() 函数用于返回数组的长度
索引数组：

<?php
$cars=array("Volvo","BMW","SAAB");
echo "I lik101; " . $cars[0] . ", " . $cars[1] . " and " . $cars[2] . ".";
?>

遍历关联数组:

<?php
$age=array("Bill"=>"35","Steve"=>"37","Peter"=>"43");

foreach($age as $x=>$x_value) {
  echo "Key=" . $x . ", Value=" . $x_value;
  echo "
";
}
?>

运行结果:
Key=Bill, Value=35
Key=Steve, Value=37
Key=Peter, Value=43
多维数组:

<?php
$cars = array
   (
   array("Volvo",33,20),
   array("BMW",17,15),
   array("Saab",5,2),
   array("Land Rover",15,11)
   );
   
for ($row = 0; $row <  4; $row++) {
   echo "<p><b>行数 $row</b></p>";
   echo "<ul>";
   for ($col = 0; $col <  3; $col++) {
     echo "<li>".$cars[$row][$col]."</li>";
   }
   echo "</ul>";
}
?>

运行效果：
行数 0

Volvo
33
20
行数 1

BMW
17
15
行数 2

Saab
5
2
行数 3

Land Rover
