<p>我正在尝试将我的数组格式化成这样的形式：姓名是John，年龄是30。这是我的示例数组和代码：</p>
<pre class="brush:php;toolbar:false;">$user = array(
'name' => 'John',
'age' => 35
);
echo key($user)." is ".($user[key($user)]).","; // prints "name is John,"</pre>
<p>如果没有更多的结果要打印出来，逗号(,)将会消失。<br /><br />我对逻辑不太擅长，但你能帮我吗？这将是一个很大的帮助！提前谢谢。</p><p><br /></p>

$user = array( 'name' => 'John', 'age' => 35 ); // echo key($user)." is ".($user[key($user)]).","; $counter = count($user); $i = 1; $res = ''; foreach ($user as $key => $value) { $res .= $key. " is ". $value; if ($counter != $i) { $res = $res .", "; } $i = $i + 1; } echo $res;$values =[]; foreach ($user as $key => $value) { $values[] = "{$key} is {$value}"; } echo implode(', ', $values);或者
$values = array_map(fn($key, $value) => "{$key} is {$value}", array_keys($user), $user); echo implode(', ', $values);
