我需要在数组中有JSON对象,如:
[{"term":"hemisected","description":"Cut into two equal parts; to bisect, especially along a medial longitudinal plane."},{"term":"polyuria","description":"A condition usually defined as excessive or abnormally large production or passage of urine."},{"term":"dyspnoea","description":"Shortness of breath."}]
然而,以下是作为单独的对象输出JSON:
while ($row = mysql_fetch_array($result)) {
$data = array(
'term' => $row['term'],
'description' => $row['definition']
);
echo json_encode($data);
}
:
{"term":"hemisected","description":"Cut into two equal parts; to bisect, especially along a medial longitudinal plane."}{"term":"polyuria","description":"A condition usually defined as excessive or abnormally large production or passage of urine."}{"term":"dyspnoea","description":"Shortness of breath."}
目前,json结构没有很好地构建,因为它在循环期间被调用。它必须在构建数组(在本例中为$data
)之后调用。考虑这个例子:
$data = array();
while ($row = mysql_fetch_array($result)) {
$data[] = array(
'term' => $row['term'],
'description' => $row['definition'],
);
}
echo json_encode($data);
