使用php解析url

问题描述：

I am having problem parsing this url using php language. I don't know if it is JSON or a normal API. I need to get "ask" and "bid" from each one. Thank you so much.

http://www.fxgrow.com/quotes/quotes.php

it's structure is like this:

{
EURUSD: {
    dir: 1,
    ask: "1.13729",
    bid: "1.13724"
},
USDJPY: {
    dir: 1,
    ask: "119.365",
    bid: "119.359"
},
USDCHF: {
    dir: 1,
    ask: "0.94013",
    bid: "0.93994"
},
GBPUSD: {
    dir: 1,
    ask: "1.54218",
    bid: "1.54209"
},
AUDUSD: {
    dir: 1,
    ask: "0.77979",
    bid: "0.77973"
},
NZDUSD: {
    dir: 1,
    ask: "0.75103",
    bid: "0.75092"
},
GBPJPY: {
    dir: 1,
    ask: "184.081",
    bid: "184.064"
},
EURGBP: {
    dir: 1,
    ask: "0.73749",
    bid: "0.73743"
}

我在使用php语言解析此url时遇到问题。我不知道它是JSON还是普通的API。我需要从每个人那里得到“询问”和“出价”。非常感谢你。 p>

$json = file_get_contents('http://www.fxgrow.com/quotes/quotes.php');
$data = json_decode($json);

foreach ($data as $key => $value) {
  echo $key . ": ask = " .$value->ask ." | bid =".$value->bid . " <br />";
}

答

Just use json_decode. You can then access the data as an object eg.

$data = file_get_contents('http://www.fxgrow.com/quotes/quotes.php');
$decoded = json_decode($data);
print_r($decoded);
print '<p>EURUSD ask: ' . $decoded->EURUSD->ask . '</p>';

答

it is pure json formatted data so you can parse it using built in functions.

$data=' { EURUSD: { dir: 1, ask: "1.13729", bid: "1.13724" }, USDJPY: { dir: 1, ask: "119.365", bid: "119.359" }, USDCHF: { dir: 1, ask: "0.94013", bid: "0.93994" }, GBPUSD: { dir: 1, ask: "1.54218", bid: "1.54209" }, AUDUSD: { dir: 1, ask: "0.77979", bid: "0.77973" }, NZDUSD: { dir: 1, ask: "0.75103", bid: "0.75092" }, GBPJPY: { dir: 1, ask: "184.081", bid: "184.064" }, EURGBP: { dir: 1, ask: "0.73749", bid: "0.73743" }';

$json=(object)json_decode( $data, true );

foreach( $json as $key => $value ){
    $o=(object)$value;
    echo $key.' '.$o->dir.' '.$o->ask.' '.$o->bid.'<br />';
}

答

Try this..

<?php
$test='{"EURUSD":{"dir":1,"ask":"1.14498","bid":"1.14492"},"USDJPY":{"dir":1,"ask":"118.729","bid":"118.724"},"USDCHF":{"dir":1,"ask":"0.93974","bid":"0.93944"},"GBPUSD":{"dir":1,"ask":"1.54587","bid":"1.54579"},"AUDUSD":{"dir":1,"ask":"0.77758","bid":"0.77754"},"NZDUSD":{"dir":1,"ask":"0.75293","bid":"0.75283"},"GBPJPY":{"dir":0,"ask":"183.540","bid":"183.525"},"EURGBP":{"dir":1,"ask":"0.74076","bid":"0.74063"}}';
$data=json_decode($test ,true);

foreach($data as $value)
{
$array=array();
$array[]=$value;
foreach($array as  $val)
{
echo $val['ask']."</br>";
echo $val['bid']."</br>";
}

}
