Question

通过使用下面的PHP输出下面的值。但是因为我无法控制API输出，所以我想尝试将数据添加到另一个输出中，例如{"id":0,"name":"Begin","description":"this is my description","url":"http://domain.com"}

有人可以帮忙吗？

PHP

<?php
$jsonurl = "/api/styles";
$json = file_get_contents($jsonurl);

echo $json;
?>

OUTPUTS

[{"id":1,"name":"Pale","description":"this is my description","url":"http://domain.com"},{"id":2,"name":"Dawn","description":"this is my description","url":"http://domain.com"}]

Answer 1

这是你的想法吗？

<?php
$jsonurl = "/api/styles";
$json = file_get_contents($jsonurl);
$json = '[{"id":0,"name":"Begin","description":"this is my description","url":"http://domain.com"},' . substr($json, 1);
echo $json;
?>

输出：

[{"id":0,"name":"Begin","description":"this is my description","url":"http://domain.com"},{"id":1,"name":"Pale","description":"this is my description","url":"http://domain.com"},{"id":2,"name":"Dawn","description":"this is my description","url":"http://domain.com"}]

Answer 2

$jsonurl = "/api/styles";
$json = file_get_contents($jsonurl);
$begin = '{"id":0,"name":"Begin","description":"this is my description","url":"http://domain.com"}';

$data = json_decode($json);
array_unshift($data, json_decode($begin));

echo json_encode($data);

Answer 3

如果它真的是json，解析它（decode_json（））并打印它，无论如何。

Answer 4

我不确定你想要“prepend”的是什么，但是你可以把它变成一个PHP数组，反过来然后将新元素推到数组上。

$json = file_get_contents($jsonurl);
$array = json_decode($json, true);
$reversed = array_reverse( $array );
$reversed[] = ['id' => 0, 'name' => 'Something];

将其反转并编码。

PHP前置一个数组
