извлекать или извлекать данные из Json в php и вставлять в базу данных mysql

Question

Может ли кто-нибудь помочь мне получить данные из этого json-скрипта, сгенерированного из yql. Я хочу, чтобы хранить данные в MySQL, который награбленных отсюда ... Я хочу, чтобы извлечь или захватить Datas AskRealtime, BidRealtime, LastTradeDate, LastTradePriceOnly, LastTradeTime, Ask

<?php 
session_start(); 
query= Insert into table .....value ... 
?> 

Я хочу сделать что-то вроде вышеприведенного сценария от ниже json. лучше, если я могу сразу же распечатать распакованные данные в одной и той же страницы в одном из HTML таблицы, не отправляя его в MySQL и вытягивать данные оттуда ...

Answer 1

Если я правильно понимаю ваш вопрос, вы хотите принять, что JSON и быть в состоянии получить доступ к данным в? Чтобы сделать JSON немного проще в использовании, я бы предложил использовать следующий код, который использует json_decode function, который преобразует JSON в полезный массив php. (Я включил эхо заявление, так что вы можете увидеть, что в результате ассоциативный массив выглядит)

$yql_json =

}'; 

$yql_results = json_decode($yql_json, true); 
echo "<pre>".print_r($yql_results, true)."</pre>"; 

вход $ yql_json является сам JSON в виде строки (однако собирать и хранить его) и значение истинного передается в функцию, возвращает функцию ассоциативный массив, который хранится в $ yql_result. После этого вы можете легко получить доступ ко всем его элементам. Надеюсь, я ответил хотя бы на часть вашего вопроса. Удачи с проектом.
