所以我用这个：
[<?php
foreach ($gPerformance as $row) {
echo json_encode($row) . ",";
}
?>]
不幸的是，这回应了这个：

你能解释一下为什么最后一个元素有{}括号吗？即使我向它添加第25个数组，第24个也保留括号，我不知道为什么。
答案 0 :(得分：6)
为了编码为数组文字而不是对象，数组必须是非稀疏的索引数组。
在您的情况下，您的最后一个数组缺少[7]，使其稀疏，因此编码为对象。
答案 1 :(得分：1)
如您所见，最后一行是具有指定键的数组：
{"0":24,"1":94,"2":96,"4":98,"5":82,"6":69,"8":97,"9":98,"10":96,"11":98,"12":97,"13":99}
为什么呢？因为你错过了键＃34; 3＆＃34;，这是你输入的输入，但不是json输出。检查输入数组和最后一行的键。
如果您不想编辑输入数组，请执行以下操作：
[<?php
foreach ($gPerformance as $row) {
echo json_encode(array_values($row)) . ",";
}
?>]
