您好我正在使用Bing网络搜索API，并需要一些帮助，使用PHP将JSON转换为html。所以我想能够使用foreach（）和if（）语句打印选择性员工。我已经看过其他的主题，但我无法弄清楚这是什么问题。
这是一个JSON示例：

我想打印一些内容＆＃34; webPages＆＃34;，我使用以下php代码：
$links = json_decode($json, TRUE);
foreach ($links['webPages'] as $j => $v) {
if($j=="value"){
foreach ($v as $k => $w) {
print $k . ": " . $w;
}
}
}
我收到以下错误：
Notice: Array to string conversion
它打印出来：
0: Array
1: Array
...
7: Array
事先谢谢。
答案 0 :(得分：0)
答案 1 :(得分：0)
你打算这个？

$links = json_decode($json);
$links = objectToArray($links);
foreach ($links as $j=>$v) {
//print $j.'<br>';
if($j == "webPages"){
foreach ($v as $k) {
if (is_array($k)){
foreach ($k as $i=>$t){
if (is_array($t)){
foreach ($t as $l=>$m){
print "<b> $l </b>" .' : ' .$m.'<br>';
}
}
}
}
}
}
}
function objectToArray($stdClass) {
if (is_object($stdClass)) {
//recupera le proprietà dell'oggetto
$stdClass = get_object_vars($stdClass);
}
if (is_array($stdClass)) {
//ritorna l'array convertito in oggetto per chiamata ricorsiva
return array_map(__FUNCTION__, $stdClass);
}
else {
//ritorna l'array
return $stdClass;
}
}
同样以这种方式有一个foreach in less：）
$links = json_decode($json);
$links = objectToArray($links);
foreach ($links['webPages'] as $j => $v) {
if(is_array($v)){
foreach ($v as $k => $w) {
if (is_array($w)){
foreach($w as $t=>$l){
print '<b>'.$t."</b> : ".$l.'<br>';
}
}
}
}
}
