如何从动态json的url将特定字符串转换为int？

I would like to remove "" from a few strings from json which updates every few minutes (http://zergpool.com/api/status).

for example:

{"bitcore":{"name":"bitcore","port":3556,"coins":1,"fees":0,"hashrate":0,"workers":0,"estimate_current":"0.00001745","estimate_last24h":"0.00001756","actual_last24h":"0.00000","hashrate_last24h":105820474.1458},

Fields:

"estimate_current":"0.00001745" -> "estimate_current":0.00001745

"estimate_last24h":"0.00001756" -> "estimate_last24h":0.00001756

"actual_last24h":"0.00000" -> "actual_last24h":0.00000

Since the numbers change all the time, is it possible to write a PHP to convert them in real time? This is what I did.

<?php

$url = 'http://zergpool.com/api/status';
$data = file_get_contents($url);

$manage = json_decode($data,true);

//$aha = (int)preg_replace("/[^\d]+/","",$manage); // tried removing them like this... doesn't work.

echo json_encode($manage)

doesn't work :(

You can use this to remove quotes from numeric values in JSON.

$encoded = json_encode($data, JSON_NUMERIC_CHECK);

Supported in the versions >= PHP 5.3

Try this:

$json = file_get_contents("https://www.ahashpool.com/api/status/");
$ar = json_decode($json, TRUE);
$filter = [];
foreach ($ar as $k => $sub_ar) {
    foreach ($sub_ar as $sub_k => $sub_v) {
        if(preg_match('/^[0-9]*\.[0-9]+$/', $sub_v)){
            $filter[$k][$sub_k] = (float) $sub_v;
        } else {
            $filter[$k][$sub_k] = $sub_v;
        }
    }
}
echo "<pre>";
var_dump($filter);
die();

echo str_replace( '"', '' ,$data); 

will remove all the double quotes.

I don't understand why you are trying to remove the double quotes from the $manage line. You can just access the elements of the json that are returned in $manage and convert to float.

$firstString = $manage['bitcore']['estimate_current']; 
$firstFloat = (float)$firstString;
var_dump($firstFloat);

or

echo 'floatval=' . floatval($firstString);
