php解析多个json文件，循环并在表中显示

php json parsing loops

php解析多个json文件，循环并在表中显示,php,json,parsing,loops,Php,Json,Parsing,Loops,我有一个脚本，可以多次解析json文件并在表中显示数据要解析的文件由字符串组成，而不是由要解析的2值标记组成的filename.json 例如：www………../idr-gold.json（其中idr代表印度尼西亚货币）国家是155个，所以我的ID是1到155，代表155个不同的标签所以我做的是一个循环，每次运行添加+1到$x，所以$x被插入到一个脚本中，找到ID、countryName和countryCurrency之间的对应关系，这样每次循环运行我都会用丢失的标记构建155次url。

我有一个脚本，可以多次解析json文件并在表中显示数据

要解析的文件由字符串组成，而不是由要解析的2值标记组成的filename.json

例如：www………../idr-gold.json（其中idr代表印度尼西亚货币）

国家是155个，所以我的ID是1到155，代表155个不同的标签

所以我做的是一个循环，每次运行添加+1到$x，所以$x被插入到一个脚本中，找到ID、countryName和countryCurrency之间的对应关系，这样每次循环运行我都会用丢失的标记构建155次url。然后脚本继续解析Json并返回一个表

问题有二： 1）我希望在解析file.json之后显示表中的每一行（因此循环$x=1，解析www..idr-gold.json-->返回一个包含数据的表行；而不是$x=2，www..usd-gold.json等等）。我尝试过移动脚本部分，但没有任何效果

2）我需要解析的时间真的很长。。。是我的脚本的一部分，还是跨域分析太慢？似乎我不会每次运行都“关闭”或“清空”脚本，这样数据就会不断增加，从而加重负载。（关于这一点，我已经了解到这可能是一个跨服务器数据传输问题，因此我的解决方案将是第一个问题。如果我在页面运行结束时逐行显示组成表，而不是所有表，我将有一个php文件，它将平均显示1秒x 155次数据，尽管页面需要2分钟（1秒x 155次）在给你看任何东西之前

下面是代码：

// var declaration (here I have ex. $italyID = 7 and $italyCurrency = itl)

// LOOP da 0 a 155
$x = 0; 
do{
// TEST    echo "The number is: $x <br>";
$iscountryID = ("$country".$x."");

$currencyVarName = ""; 
if ($iscountryID == 0) {
    $currencyVarName = $goldCurrency;
    } elseif ($iscountryID == 1) {
    $currencyVarName = $polandCurrency;

    };

// if Currency name it isn't null
if ($currencyVarName != NULL) {
$urlLoopBuy =  strtolower("....exchange/".$currencyVarName."-gold.json");
$jsonLoopBuy = file_get_contents($urlLoopBuy);
$outLoopBuy = json_decode($jsonLoopBuy, true);

//json data parse
$buycurrency = $outLoopBuy['buy']['currency'];

} else { // if currency name is NULL
$buycurrency = "record problem";
$sellcurrency = "record problem";

//add +1 to loop
$x++;

};
} while ($x <= 155);

$linktopage = "...monetarymarket.html?buyerCurrencyId=".$buyercountryID."&sellerCurrencyId=".$sellercountryID."";

你也能给我们提供一个json示例吗？当然可以。我用我的json示例编辑了主消息。我在问自己。在短时间内可能会有太多询问的问题。你认为如果我在每次循环运行后倒计时5秒，那么服务器intterogated有时间做“它必须做的事情”会有帮助吗？我正在尝试将所有代码转换为singole函数，但变化不大！
