HomeBackend DevelopmentPHP Tutorial 请问,php如何打印出从服务器返回的原始json

请教,php怎么打印出从服务器返回的原始json?
我用一个php从服务器请求,服务器返回了标准格式的json,然后赋值到$a,我现在想把原始json数据打印出来,怎么办?
echo只显示一个Array,print,prinf是空,print_r是显示出了,但已经不是json格式的数据了。

------解决方案--------------------
显然$a存储的不是json字符串,而是经过json_encode()后的PHP的数组。
相应的,你可以echo json_decode($a);
------解决方案--------------------
echo json_encode($a);即可,$a明显是decode过的字符串……
------解决方案--------------------
你使用了新浪的SDK,而SDK的作用即在开发便捷。虽然/statuses/home timeline的返回格式是json,但还是经过了SDK内部处理。
PHP不能直接操作json字符串,因此这个SDK帮你预先把json转换为PHP的数组。
------解决方案--------------------

PHP code

$ch = curl_init();  
$ch = curl_init($url) ;  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; 
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ; 
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
 $out = curl_exec($ch);
 
 $out = trim($out);
 curl_close($ch);
 $out = json_decode($out, true);
 var_dump($out);

探讨

非常感谢你提供了一个另外的解决方法,但是我用的前端html+js的异步处理方式,所以非常好用但是用不上。学习了!引用:

$ch = curl_init();
$ch = curl_init($url) ;
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ;
