如何获取 PHP 单个数组值

Question

How I can get only the value "RGE_NOMBRE" for fill an imput text in PHP from the following array:

object(stdClass)#1367 (1) 
{
 ["GetContribuyentesResult"]=> string(161) "{"RGE_RUC":"102318239",**"RGE_NOMBRE"**:"P ARISTIDES HERNANDEZ C POR A","NOMBRE_COMERCIAL":"P ARISTIDES HERNANDEZ","CATEGORIA":"0","REGIMEN_PAGOS":"2","ESTATUS":"2"}" 
}

Answer 1

Assuming that your response is this:

{"RGE_RUC":"102318239","RGE_NOMBRE":"P ARISTIDES HERNANDEZ C POR A","NOMBRE_COMERCIAL":"P ARISTIDES HERNANDEZ","CATEGORIA":"0","REGIMEN_PAGOS":"2","ESTATUS":"2"}

what you have is a JSON object. To get what you want, decode the JSON and extract your data from the resulting object:

$jsonObject = json_decode($response);
$requiredData = $jsonObject->RGE_NOMBRE; ///  P ARISTIDES HERNANDEZ C POR A

Answer 2

While your question is not very clear on how you get the string as a value of stdClass object with key GetContribuyentesResult , I am guess you are inserting the key later.

As per your comments you are doing $data= (array) $response; and your result is a string. Again this is not possible because you are trying to cast an array. Hence I assume $response is the string you are talking about.

This string is a JSON string about which you can read more on this page .

And you can convert a json string to an array with json_decode() in php. This is how you can extract any key from a json string.

$response = '{"RGE_RUC":"102318239","RGE_NOMBRE":"P ARISTIDES HERNANDEZ C POR A","NOMBRE_COMERCIAL":"P ARISTIDES HERNANDEZ","CATEGORIA":"0","REGIMEN_PAGOS":"2","ESTATUS":"2"}';

# decoding to an associative array
$array = json_decode($response, true); ## or json_decode($response) to get an stdClass object
$requiredValue = $array['RGE_NOMBRE']; ## or $requiredValue = $array->RGE_NOMBRE; for stdClass object
