JSON循环给出的数组超出预期

Question

我的PHP代码有一个奇怪的情况。
基本上我想输出目录中所有JSON文件的JSON，但是出于意想不到的原因，它给了我两个 JSON数组，一个是错误的，一个是正确的。
下面的代码：

$files = glob("players/*"); 
$nFiles = count($files); 

foreach($files as $file){ 

    $jsonArray[] = array(

    "name" => "a name", 
    "reason" => "a reason", 
    "date" => "a date" 

); 

    echo json_encode($jsonArray); 
} 

输出：

[{"name":"a name","reason":"a reason","date":"a date"}] -- here the loop stops (idk why) and it begins again -- [{"name":"a name","reason":"a reason","date":"a date"},{"name":"a name","reason":"a reason","date":"a date"}]

你应该把echo语句foreach循环之外：

$files = glob("players/*"); 
$nFiles = count($files); 

foreach($files as $file){ 

    $jsonArray[] = array(

    "name" => "a name", 
    "reason" => "a reason", 
    "date" => "a date" 

); 
} 
    echo json_encode($jsonArray);
