PHP数组问题？

Question

当数组在回显时显示其内容时，尝试停止重复单词has been entered。

这是代码。

echo "$array[$x] has been entered";

Answer 1

echo implode(", ", $array) . " has been entered";

Answer 2

呃，echo $array[$x];？

Answer 3

...

怎么样

echo $array[$x]." has been entered";

Answer 4

更新后的评论：

您可以使用类似

的内容

foreach ($array as $a) {
  echo $a;
}

echo "has been entered";

Answer 5

至于我能得到你的问题;尝试以下代码：

foreach($array as $key => $value)
{
  // if this is the first item
  if ($key === 1)
  {
    echo "$array[$key] has been entered";
  }
  else
  {
    echo $array[$key];
  }
}

Answer 6

使用单引号而不是双引号：

echo implode(', ', $array) . ' has been entered';
