Question

I am doing an ajax call from my webpage to get response from getWeather.php page in JSON format. Sometimes i get result but mostly i don't. But whenever i browse this link, it always give me result in JSON format. Am i doing something wrong in my getWeather.php?

https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text%3D%27lahore%27)%20AND%20u%3D%27c%27&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=

getWeather.php implementation:

<?php
$city = $_GET['city'];

echo file_get_contents("https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text%3D%27".$city."%27)%20AND%20u%3D%27c%27&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=");
