Please help. Doing a project that can get Gold Price from the Web.

Tried this function and it works on my LOCALHOST but not in my free server.

<!DOCTYPE html>


<?php


function get_gold(){
	$url='http://money.cnn.com/data/commodities/';
	//$url='http://vikingspawnshop.net16.net/getgold.php';
	$data = file_get_contents($url);
	//preg_match("/[0-9]*\,[0-9]*\..[0-9]*/",$data,$converted);
	preg_match("/[0-9]*\,[0-9]*\..[0-9]*/",$data,$converted);
	echo $converted[0];
}

whats the error message? increase error_reporting

Noppy · July 14, 2016, 2:08pm

does file_get_contents work? We have an api that stopped working the other day as the security on the site we were picking the json file up from had changed and was stopping file_get_contents. Just try a simple test like

<?php $test = file_get_contents('http://www.example.com'); echo $test;?>

Think that should work although just typed that now so might have missed something (others might have to correct). But hopefully that should show you if file_get_contents is working or not.

Hi @chorn, there is no error
just that the value isn’t displaying.

you can check it out using http://vikingspawnshop.net16.net/goldprice.php

In my local host, the $value shows up.

markxavier2016 · July 14, 2016, 2:13pm

http://vikingspawnshop.net16.net/goldprice.php

The $value isn’t showing up in the uploaded version @Noppy.
Tried editing the codes but still, it shows in my localhost but the uploaded version.

You have an echo inside the function and you echo the function when you call it. I’m not sure which is right, but I can;t see you want both!

markxavier2016 · July 14, 2016, 2:19pm

Here’s the updated code. Still not working.

<?php $url='http://money.cnn.com/data/commodities/'; //$url='http://vikingspawnshop.net16.net/getgold.php'; $data = file_get_contents($url); //preg_match("/[0-9]*\,[0-9]*\..[0-9]*/",$data,$converted); preg_match("/[0-9]*\,[0-9]*\..[0-9]*/",$data,$converted); $value=$converted[0]; ?> Home - Viking's Pawnshop

The last statement in your function wants to be

return $converted[0];

I think. If that doesn’t work I would check the versions of PHP on your localhost and on your host.

markxavier2016 · July 14, 2016, 2:53pm

Guys, found the problem. My free hosting wont let me post it.
By the way, thanks for all your help.

oddz · July 14, 2016, 2:57pm

Your free hosting won’t let you crawl cnn.
