我正在尝试将此cURL命令行调用转换为PHP脚本。我读过很多关于它的文章，并尝试了几个选项，但没有一个能够返回结果。下面是命令行调用：
curl -v https://api.sandbox.paypal.com/v1/oauth2/token '
-H "Accept: application/json" '
-H "Accept-Language: en_US" '
-u "EOJ2S-Z6OoN_le_KS1d75wsZ6y0SFdVsY9183IvxFyZp
:EClusMEUk8e9ihI7ZdVLF5cZ6y0SFdVsY9183IvxFyZp" '
-d "grant_type=client_credentials"
这是我到目前为止尝试过的：
$data = "grant_type=client_credentials";
$url = "https://api.sandbox.paypal.com/v1/oauth2/token";
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_HEADER,true);
curl_setopt($ch,CURLOPT_HTTPHEADER, array("Accept:application/json","Accept- Language:en_US"));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, "[$idclient]:[$sekret]");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
var_dump($result);
请帮助我将其转换为PHP脚本调用。
谢谢
