配列の要素を取得

```php
$ages = [10, 20, 30, 40, 50];
$age = $ages[$(1)];
```

```php
$colors = ['red', 'blue', 'midori', 'yellow'];
$colors[$(1)] = '$(2)';
```


```php
$colors = array('あか', 'あお', 'みどり', 'きいろ');
$colors$(1) = 'しろ';
```

```php
$colors = ['red', 'blue', 'green', 'yellow'];
$(1)($colors[$(2)]);
```

```php
$colors = ['red', 'blue', 'green', 'white', 'brown'];
array_splice($colors, $(1), $(2));
```


```php
$colors = ['red', 'blue', 'green', 'white', 'brown'];
$replaced = ['black']; 
$rep_colors = array_splice($colors, $(1), $(2), $replaced); 
```

```php
$sum = 0;
$scores = [43, 72, 80, 56, 94];
$(1)($i = $(2); $i $(3) count($scores); $i++) {
    $sum += $scores[$i] ;
}
echo $sum;
```

```php
$sum = 0;
$scores = [43, 72, 80, 56, 94];
$(1)($scores $(2) $score) {
    $sum += $score;
}
echo $sum;
```
