PHP Stock Market API

Looking to grab the latest stock market data? There’s a surprising lack of stock market APIs out there and even fewer that work consistently or affordable. Never fear, the PHP Stock Market API is here!

The PHP Stock Market API is a simple PHP class that uses the Yahoo! Finance API allowing you to retrieve up to 20 current data points for a particular symbol. It’s simple to implement and doesn’t require you to learn how to use the Yahoo! API.

UPDATE (Nov. 28, 2014, v1.3): getData now allows an array to pull multiple stocks at once (thanks @d3vit).
UPDATE (Jan. 27, 2014, v1.2): You can now also retrieve historical data (open, high, low, close, volume & adjusted close).

PHP Stock Market API Usage

With just a few lines of code, you can easily retrieve 20 current data points. Here’s how it works:

<?php
require_once('class.stockMarketAPI.php');
?>

<h1>Current Stock Information for AAPL</h1>

<?php
$StockMarketAPI = new StockMarketAPI;
$StockMarketAPI->symbol = 'AAPL';
?>
<pre><?php print_r($StockMarketAPI->getData());?></pre>

<?php
$start = '01-01-2013';
$end = '01-07-2013';
?>
<h1>Historical Stock Information for AAPL (<?php echo $start ?> - <?php echo $end ?>)</h1>
<?php
$StockMarketAPI = new StockMarketAPI;
$StockMarketAPI->symbol = 'AAPL';
$StockMarketAPI->history = array(
  'start'    => $start,
  'end'    => $end,
  'interval' => 'd' // Daily
);
?>
<pre><?php print_r($StockMarketAPI->getData());?></pre>

<hr>

<h1>Stock Information for AAPL, MSFT, GOOGL</h1>
<?php
$StockMarketAPI = new StockMarketAPI;
$StockMarketAPI->symbol = array('AAPL', 'MSFT', 'GOOGL');
?>
<pre><?php print_r($StockMarketAPI->getData());?></pre>

    Yahoo finance API is not available anymore. I have moved to MarketXLS after this change, much more reliable data.

    • please how could i make this codes function so i could view the interface

    • Are you using MarketXLS (w/Excel) or MarketXLS-API (with your own script). If “your own script” what language did you use? I’m going to start work on a php script.

    The fix for the change in the API can be found here:
    https://github.com/scheb/yahoo-finance-api/issues/8#issuecomment-303094304

  4. Hello, Yahoo has changed API Query, could you perhaps adopt script? Thanks.

  5. I’ve been using this API as the backbone to a personal project to gather stock information and it has worked flawlessly up until this weekend. Worked correctly last on May 26th, 2017.

    I have made no changes to my projects code in several months and have had no issues until this weekend and now the API is unable to retrieve data?

    Curious if it is still working for others or if Yahoo finally changed their output methods or blocked this type of data requesting? Any information would be helpful, thanks

    Great work. This code provides much useful information about stocks.

  7. Hi Ben, thanks for this! Working great for me. I can’t seem to find any documentation on changing the interval from “daily” (as you have it) to, say, hourly, or minutes. I’m trying to get the current, or previous day’s intraday data for a stock.

    Thanks!

  8. Still have the problem with Start/ End Date when using historical data. If I set for symbol = ‘AAPL’:
    $start = ’01-01-2013′;
    $end = ’31-12-2013′;
    I get historical data from 01-01-2013 until now, which is 16-07-2016….Did not find a way to fix this….:-(

    Another question:
    Is there any way of using this API not only for historical stock, but also for historical currency quotes like ‘EURUSD=X’ or commodities like ‘NG=F’ which would be natural gas. See list of commodities/ currencies at yahoo:
    http://finance.yahoo.com/commodities?ltr=1
    http://finance.yahoo.com/currencies?ltr=1

    That would really be a big thing….I really would appreciate using this API like that. 🙂
    Thanks for support and help.

    Since Yahoo Finance told us that they will drop the realtime update for the gold price, is it possible to use Kitco for source instead?
    I don’t know is it possible to use it with this API without huge modification.
    Regards

  10. great work man! thanks for sharing, really made my life easier..

  11. thanks ben, it work for me.

  12. This really works fine!

  13. Hey Ben,

    This is pretty cool but when I try to save the historical data into a variable; ie: $myhistoricaldata = $StockMarketAPI->getData(), the whole array get printed to the page rather than being saved to my variable. I’m not sure what’s going on.

    My code would be as follows:

    // Get daily historical data for AAPL
    $StockMarketAPI = new StockMarketAPI;
    $StockMarketAPI->symbol = 'AAPL';
    $StockMarketAPI->history = array(
    'start' => '2013-1-1', // yyyy-m-d
    'end' => '2013-12-31', // yyyy-m-d
    'interval' => 'w' // weekly
    );
    $myhistoricaldata = $StockMarketAPI->getData());

    Any thoughts? Thanks.

  14. Great article and thank you for putting this together.

    I forked and made a modification to your source so that the getData function will take an array. On GitHub here: https://github.com/d3vit/php-stock-market-api

    Feel free to integrate if you’d like.

  15. The code actually is broken currently when I attempt to run it. Quick fix is to move

    $start = '2013-1-1';
    $end = '2013-12-31';

    into the actual <?php block instead of having it in it's own separate blocks underneat the . The strange thing is, the code has the , then creates variables for $start and $end, but doesn’t actually display it there. Not sure why it was written like that in the first place. All of this is in the index.php file, and after making that change, the code worked great. Thank you!

    • Thanks for the feedback. Just released a new version (1.3, thanks to @d3vit) that should work better for you. Let me know if you run into any problems.

  16. Those codes are real life saver specifically for brokers who usually “misplace” their datas. Thanks Ben!
