php 具有数组索引值的数组

Question

我试图让 $adjective 数组有一个来自 $currentCount 的值，但它给了我一个错误。

它说语法错误。 谢谢！

$currentCount = [0, 0, 0, 0, 0, 0];
$adjectives=["a","b","c","d","e"];

echo "<h1> The $adjectives[$currentCount[0]] ";

Answer 1

您应该将字符串和数组变量与索引值分开，因为它将方括号[]作为字符串读取。

$currentCount = [0, 0, 0, 0, 0, 0];
$adjectives = ["a", "b", "c", "d", "e"];

echo "<h1> The " . $adjectives[$currentCount[0]];

Answer 2

您应该使用{}将字符串中的 PHP 部分包装起来。 尝试这个

$currentCount = [0, 0, 0, 0, 0, 0];
$adjectives=["a","b","c","d","e"];

echo "<h1> The {$adjectives[$currentCount[0]]} ";
