Are you sure your shared hosting allows connections to remote url - Unlikely
Most shared hosts tend not to set allow_url_fopen to true in php.ini
Maybe try using curl instead
Frage
I am building a stock analysis website to use stock information such as price history etc. I will implement some of my own algorithms once I get the data but I am getting trouble obtaining the historical data.The website is hosted on the free web-hosting of biz.nf. The connect.php file that is included contains all the needed sql info and connects to the database. I have error checks there so I know thats not the problem. I have also tried to copy/paste the links manually and they work so I am creating the URLs properly. I came across some similar topics on this website and on others, but I do not see a clear solution how to fix it or a clear reason why it is happening. Is yahoo blocking me? Also, I would like to mention that I am quite new to php programming but I have a serious background in C and C++ so please consider this when providing any help, if you can. Thanks in advance!
Here is my code for the index.php file that gets executed
Code:
<html>
<head>
<title>StockGrader</title>
</head>
<body bgcolor="green" text="black" link="red">
<div id="header">
<hr>
<h1>Welcome To <b><i>StockGrader</b></i><h1/></hr>
<?php
include("phpINCLUDES/connect.php");
//function that creates a url from which to download data
function createURL($ticker)
{ $currentMonth = date("n") - 1; //"n" current month as a 1-digit number
$currentDay = date("j"); //"j" current day as a 1-digit number
$currentYear = date("Y"); //"Y" current year as a 4-digit number
echo "current URL is http://ichart.finance.yahoo.com/table.csv?s=$ticker&d=$currentMonth&e=$currentDay&f=$currentYear&g=d&a=3&b=10&c=2013&ignore=.csv";
echo "\n\n\n";
return "http://ichart.finance.yahoo.com/table.csv?s=$ticker&d=$currentMonth&e=$currentDay&f=$currentYear&g=d&a=3&b=10&c=2013&ignore=.csv";
}
//function to download data from a url and store into a file
function getCSVFile($URL, $outputFile)
{
**$content = file_get_contents($URL);** //goes to the file located at this link and downloads the full file contents as a string of data
//replace a string which is the first parameter with the string in the second parameter. the string being replaced is in the third parameter
$content = str_replace("Date,Open,High,Low,Close,Volume,Adj Close","", $content);
//removes all white space
$content = trim($content);
//write a string into a file
file_put_contents($outputFile, $content);
}
function fileToDatabase($txtFile, $tableName)
{
$file = fopen($txtFile, "r");
while(!feof($file))
{
$line = fgets($file);
//separates a string
$pieces = explode(",", $line);
//stock variables
$date = $pieces[0];
$open = $pieces[1];
$high = $pieces[2];
$low = $pieces[3];
$close = $pieces[4];
$volume = $pieces[5];
// $adjclose = $pieces[6]; WE ARE NOT GOING TO USE THIS ONE USUALLY
$amount_change = $close - $open;
if($open!=0)
{ $percent_change = ($amount_change/$open)*100; }
else $percent_change = 99999;
//check if table exists or not
$sql = "SELECT * FROM $tableName";
$result = mysql_query($sql);
//if table doesn't exist
if(!$result)
{
$sql_2 = "CREATE TABLE $tableName (date DATE , PRIMARY KEY(date), open FLOAT, high FLOAT, low FLOAT, close FLOAT, volume INT, amount_change FLOAT, percent_change FLOAT)";

mysql_query(sql_3);

fclose($file);
}
function main()
{
//i don't have this file yet
$mainTickerFile = fopen("tickerMaster.txt","r");
while(!feof($mainTickerFile))
{
$companyTicker = fgets($mainTickerFile);
$companyTicker = trim($companyTicker); //trim whitespace just in case
$fileURL = createURL($companyTicker); //create url for each stock ticker
//create a directory path to each file for each ticker
$companyTxtFile = "txtFiles/".$companyTicker.".txt"; //I NEED TO CREATE THIS FOLDER ON MY SERVER
getCSVFile($fileURL, $companyTxtFile);
fileToDatabase($companyTxtFile, $companyTicker);
}
}
main();

This is the error I am getting:
[function.file-get-contents]: failed to open stream: Connection refused in /srv/disk12/1368341/www/nemanja.co.nf/index.php on line 26
I made the text in bold (2 asterisks on each side) where the error is happening.
Also, the server im hosting the website on has allow_url_fopen = 1 If it is the case yahoo.com is blocking me is there a way around this? Is there another way of getting all the historical stock data?
