PHP: ¿Cómo codificar números infinitos o NaN a JSON?
Al parecer, Infinity y NaN no forman parte de la especificación JSON, por lo que este código PHP:
$numbers = array();
$numbers ['positive_infinity'] = +INF;
$numbers ['negative_infinity'] = -INF;
$numbers ['not_a_number'] = NAN;
$array_print = print_r ($numbers, true);
$array_json = json_encode ($numbers);
echo "\nprint_r(): $array_print";
echo "\njson_encode(): $array_json";
Produce esto:
PHP Warning: json_encode(): double INF does not conform to the JSON spec, encoded as 0 in /home/septi/test.php on line 8
PHP Warning: json_encode(): double -INF does not conform to the JSON spec, encoded as 0 in /home/septi/test.php on line 8
PHP Warning: json_encode(): double NAN does not conform to the JSON spec, encoded as 0 in /home/septi/test.php on line 8
print_r(): Array
(
[positive_infinity] => INF
[negative_infinity] => -INF
[not_a_number] => NAN
)
json_encode(): {"positive_infinity":0,"negative_infinity":0,"not_a_number":0}
¿Hay alguna forma de codificar correctamente estos números sin escribir mi propiajson_encode()
¿función? Tal vez alguna solución?
