这是我用来解码的代码

function b() {
    $string = file_get_contents("/home/linux/Public/test/a.json");
    $json_a = json_decode($string, true);
    print_r($json_a);
        foreach ($json_a as $person_name) {
        print_r($person_name);
    }
}

它将Invalid argument supplied for foreach()打印为错误。 我删除了仅使用一个响应的所有响应，然后工作正常。

Answer 1

如果使用换行符分隔每个json，则可以执行

foreach (file($file_name) as $json_plain) {
    print_r(json_decode($json_plain, true));
}

file()可以将文件分割成行的数组，因此您可以解码每行。

Answer 2

 <?php

$file_name = 'a.json';
foreach (file($file_name) as $json_plain) {
    print_r(json_decode($json_plain, true));
 }
?>

您可以使用它。
