为Google Charting API构建数组并格式化JSON

您 需要 为cols 指定参数 类型 。请参阅Google Charts
JSON格式

您的PHP代码应类似于：

function test(){    $array['cols'][] = array('type' => 'string');    $array['cols'][] = array('type' => 'string');    $array['cols'][] = array('type' => 'string');    $array['rows'][] = array('c' => array( array('v'=>'20-01-13'), array('v'=>22)) );    $array['rows'][] = array('c' => array( array('v'=>'21-01-13'), array('v'=>26)));    $array['rows'][] = array('c' => array( array('v'=>'22-01-13'), array('v'=>12)));    return $array;}print json_enpre(test());

您的json代码看起来更像：

{  "cols": [    {"type": "string"},    {"type": "string"},    {"type": "string"}    ],  "rows": [    {"c":[{"v":"20-01-13"}, {"v":22} ]},    {"c":[{"v":"21-01-13"}, {"v":26} ]},    {"c":[{"v":"22-01-13"}, {"v":12} ]}  ]}
