在PHP中解析JSON

Question

我真的很努力地用PHP解析JSON字符串。下面的链接包含我试图解析的JSON：http://finance.google.com/finance/info?client=ig&q=NASDAQ:MSFT,NASDAQ:GOOG,NASDAQ:AAPL

任何人都可以帮助，我已经尝试了一切，但我仍然对此感到陌生。

谢谢。

如果没有//字符串的开始使用

$json_data = '[ { "id": "358464" ,"t" : "MSFT" ,"e" : "NASDAQ" ,"l" : "25.80" ,"l_cur" : "25.80" ,"s": "1" ,"ltt":"4:00PM EDT" ,"lt" : "Sep 2, 4:00PM EDT" ,"c" : "-0.41" ,"cp" : "-1.56" ,"ccol" : "chr" ,"el": "25.44" ,"el_cur": "25.44" ,"elt" : "Sep 6, 4:35AM EDT" ,"ec" : "-0.36" ,"ecp" : "-1.40" ,"eccol" : "chr" ,"div" : "0.16" ,"yld" : "2.48" } ,{ "id": "694653" ,"t" : "GOOG" ,"e" : "NASDAQ" ,"l" : "524.84" ,"l_cur" : "524.84" ,"s": "0" ,"ltt":"4:00PM EDT" ,"lt" : "Sep 2, 4:00PM EDT" ,"c" : "-7.66" ,"cp" : "-1.44" ,"ccol" : "chr" } ,{ "id": "22144" ,"t" : "AAPL" ,"e" : "NASDAQ" ,"l" : "374.05" ,"l_cur" : "374.05" ,"s": "1" ,"ltt":"4:00PM EDT" ,"lt" : "Sep 2, 4:00PM EDT" ,"c" : "-6.98" ,"cp" : "-1.83" ,"ccol" : "chr" ,"el": "371.45" ,"el_cur": "371.45" ,"elt" : "Sep 6, 6:02AM EDT" ,"ec" : "-2.60" ,"ecp" : "-0.70" ,"eccol" : "chr" ,"div" : "" ,"yld" : "" } ]'; 
$json_object = json_decode($json_data); 

与//使用

$json_data = '......'; 
$json_data = trim(substr($json_data,2)); 
$json_object = json_decode($json_data); 

结果

array (
    0 => 
    stdClass::__set_state(array(
    'id' => '358464', 
    't' => 'MSFT', 
    'e' => 'NASDAQ',

在您的源代码中，他们正在评论JSON。他们这样做很奇怪，但无论如何，//在一开始就把它搞砸了。

$url = 'http://finance.google.com/finance/info?client=ig&q=NASDAQ:MSFT,NASDAQ:GOOG,NASDAQ:AAPL'; 
$json = preg_replace('#^\s+//#', '', file_get_contents($url)); 
$decoded = json_decode($json); 
var_dump($decoded);
