Lab3.1 - Arrays in PHP
<?php
// put your code here
$numbers = array(1, 2, 3, 4, 5, 6, 7, 8);
$numbers = [1, 2, 3, 4, 5, 6, 7, 8];
array_push($numbers, 9);

}
echo "<br/>";
echo"Contents of integer array using foreach<br/>";
foreach ($numbers as $value) {
echo"$value ";
}
echo"<br/>";
array_pop($numbers);
echo"Contents of integer array using print_r function<br/>";
print_r($numbers);
echo"<br/>";
echo"Contents of integer array using var_dump function<br/>";
var_dump($numbers);
echo"<br/>";
$numbers = [];
for ($index = 0; $index < 6; $index++) {
$numbers[] = rand(1, 45);
}
echo "Contents of tattslotto numbers array<br/>";
foreach ($numbers as $value) {
echo"$value ";
}
echo "<br/>";
sort($numbers);
echo "Contents of tattslotto numbers array after sorting<br/>";
foreach ($numbers as $value) {
echo "$value ";
}
echo "<br/>";
?>
运行结果：
创建数组方法：
- $numbers = array(1, 2, 3, 4, 5, 6, 7, 8);
- $numbers = [1, 2, 3, 4, 5, 6, 7, 8];
添加数组元素：
- array_push($numbers, 9);
- $numbers[] = 10;
输出数组：
- for循环
- foreach函数
- print_r（）
- var_dump（）
Lab3.2 - Associative Arrays in PHP
<?php
// put your code here

"author" => "Riot Games",
"ranking" => 1,
"players" => 11500000];

foreach ($game as $key => $value) {
echo"$key : $value <br/>";
}
echo "<br/>";
$games = [
["title" => "League of lengends",
"author" => "Riot Games",
"ranking" => 1,
"players" => 11500000],
["title" => "Counter Strike Go",

"players" => 4.82]
];
echo"Displaying the contents of games <br/><br/>";
foreach ($games as $game) {
foreach ($game as $key => $value) {
echo "$key : $value <br/>";
}
echo"<br/>";
