我正在尝试为我的项目使用非官方的IMDb api。我用了这段代码。
<form name="search-imdb" autocomplete="off" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="text" name="q" title="Type Name, Title, Character etc and hit Enter" placeholder="Type Name, Title, Character etc and hit Enter" size="50" />
<input type="submit" name="submit" title="Click to Fetch Data from IMDb" value="Search IMDb" />
</form>
<?php
if (isset($_POST['submit'])){
$user_search = $_POST['q'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "imdb.wemakesites.net/api/search?q=".$user_search);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
$array = json_decode($output, true);
print_r($array);
foreach ($array as $key => $data){
if(is_array($data)){
foreach($data as $subkey => $results){
if(is_array($results)){
foreach($results as $key => $titles){
echo $titles."<br />";
}
} else {
echo $results."<br />";
}
}
} else {
echo $data."<br />";
}
}
curl_close($ch);
} else {
}
?>
我只需要获取“titles”数组的值。 (title,id,url)这是JSON代码。
Array{
"status": "success",
"code": 200,
"message": "ok",
"term": "jQuery21409989625962002346_1459839763205&q",
"search_url":"http://www.imdb.com/find?q=batmansuperman&s=all5703b359add1b",
"data": {
"results": {
"titles": [
{
"title": "Batman",
"id": "tt0096895",
"url":"http://www.imdb.com/title/tt0096895/"
},
{
"title": "Batman",
"id": "tt0059968",
"url":"http://www.imdb.com/title/tt0059968/"
},
{
"title" :"Batman v Superman: Dawn of Justice",
"id": "tt2975590",
"url":"http://www.imdb.com/title/tt2975590/"
},
{
"title": "Batman Begins",
"id": "tt0372784",
"url":"http://www.imdb.com/title/tt0372784/
}
]
}
}
这是JSON解码后的$数组。
Array ( [status] => success [code] => 200 [message] => ok [term] => megamind [search_url] => http://www.imdb.com/find?q=megamind&s=all5703f4f88841f [data] => Array ( [results] => Array ( [titles] => Array ( [0] => Array ( [title] => Megamind [id] => tt1001526 [url] => http://www.imdb.com/title/tt1001526/?ref_=fn_al_tt_1 ) [1] => Array ( [title] => Megamind [id] => tt1785464 [url] => http://www.imdb.com/title/tt1785464/?ref_=fn_al_tt_2 ) [2] => Array ( [title] => MegaMind [id] => tt1890468 [url] => http://www.imdb.com/title/tt1890468/?ref_=fn_al_tt_3 ) [3] => Array ( [title] => Mega Mindy [id] => tt0891395 [url] => http://www.imdb.com/title/tt0891395/?ref_=fn_al_tt_4 ) [4] => Array ( [title] => Megamind [id] => tt3022564 [url] => http://www.imdb.com/title/tt3022564/?ref_=fn_al_tt_5 ) [5] => Array ( [title] => Megamind: The Button of Doom [id] => tt1847645 [url] => http://www.imdb.com/title/tt1847645/?ref_=fn_al_tt_6 ) [6] => Array ( [title] => Megamind [id] => tt3624292 [url] => http://www.imdb.com/title/tt3624292/?ref_=fn_al_tt_7 ) [7] => Array ( [title] => Megamind [id] => tt2173285 [url] => http://www.imdb.com/title/tt2173285/?ref_=fn_al_tt_8 ) [8] => Array ( [title] => Mega Mindy Versus ROX [id] => tt4706602 [url] => http://www.imdb.com/title/tt4706602/?ref_=fn_al_tt_9 ) [9] => Array ( [title] => Aa Megamisama [id] => tt0872301 [url] => http://www.imdb.com/title/tt0872301/?ref_=fn_al_tt_10 ) ) [characters] => Array ( [0] => Array ( [title] => Megamind [id] => ch0194198 [url] => http://www.imdb.com/character/ch0194198/?ref_=fn_al_ch_1 ) [1] => Array ( [title] => Megamind's Mother [id] => ch0229958 [url] => http://www.imdb.com/character/ch0229958/?ref_=fn_al_ch_2 ) [2] => Array ( [title] => Megamind's Father [id] => ch0229956 [url] => http://www.imdb.com/character/ch0229956/?ref_=fn_al_ch_3 ) ) [names] => Array ( [0] => Array ( [title] => Megamind [id] => nm6292338 [url] => http://www.imdb.com/name/nm6292338/?ref_=fn_al_nm_1 ) ) [keywords] => Array ( [0] => Array ( [title] => megami [id] => megami [url] => http://www.imdb.com/keyword/megami/?ref_=fn_al_kw_1 ) ) [companies] => Array ( [0] => Array ( [title] => Megami [id] => co0544394 [url] => http://www.imdb.com/company/co0544394/?ref_=fn_al_co_1 ) [1] => Array ( [title] => Mega Mind Media [id] => co0558438 [url] => http://www.imdb.com/company/co0558438/?ref_=fn_al_co_2 ) [2] => Array ( [title] => Elm Tree Gaming [id] => co0202064 [url] => http://www.imdb.com/company/co0202064/?ref_=fn_al_co_3 ) ) ) ) )
谁能告诉我这里我做错了什么?我收到此错误 - “数组到字符串转换”
我已经尝试解决了几个小时,我一直在寻找互联网上的答案。一些帮助将非常感谢。感谢。

从我看来,这看起来像一个json而不是一个数组。在这种情况下,您应该首先执行此操作:
$array = json_decode($array, true);
当涉及到数组遍历时,你可以尝试这样的事情:
foreach($array['data']['results']['titles'] as $data) {
echo "Title:".$data['title'];
echo "<br/>";
echo "ID:".$data['id'];
echo "<br/>";
echo "URL:".$data['url'];
echo "<hr/>";
}
希望这有帮助。

假设您将要{J}数据json_decode
,data
,results
和titles
不是数组键,它们就是对象属性。尝试类似$array->data->results->titles[0];
的内容。 {
字符表示对象属性,而[
表示数组。
答案 2 :(得分:2)
使用
$json_array = json_encode($array['data']['results']['titles']);
print_r($json_array);
