PHP数组到链接内的变量

Question

I'm using the code from this website: http://blog.chapagain.com.np/php-how-to-get-stock-quote-data-from-yahoo-finance-complete-code-and-tutorial/

$stock = "GOOG";
$objYahooStock->addFormat("sl1"); 
$objYahooStock->addStock($stock);

foreach( $objYahooStock->getQuotes() as $code => $stock) {
    $stock = $stock[1];
}

However, I can't use the variable $stock inside a link. If I try to display it on the page ( echo $stock; ) it's working. I'm able to see the stock price, but I'm not able to use the variable inside a link, see below.

http://example.com/example?text=' . $stock . '%20USD

I've also tried saving the stock price to a variable without the foreach loop.

$stock = "GOOG";
$price = $objYahooStock->getQuotes();
$stock = $price[$stock][1]; 

Same result here. I'm able to display the price but I can't use it inside a link.

Does anyone see the issue? Thanks in advance.

Answer 1

Without seeing your full code, it's difficult to see what you are doing, but http://example.com/example?text=' . $stock . '%20USD http://example.com/example?text=' . $stock . '%20USD http://example.com/example?text=' . $stock . '%20USD looks as if this is HTML and not PHP?

Depending on your approach ...

PHP: echo 'http://example.com/example?text=' . $stock . '%20USD'; echo 'http://example.com/example?text=' . $stock . '%20USD';

or;

HTML: http://example.com/example?text=<?=$stock?>%20USD

EDIT: I see you are using JavaScript from your comment, so use the HTML example above.

Basically you need to analyse output. Try var_dump and see the result.

In your case $stock have some character in string. try below solution for snl1d1t1cv format:

$objYahooStock = new YahooStock;
$objYahooStock->addFormat("snl1d1t1cv");
$objYahooStock->addStock("GOOG");

$price = $objYahooStock->getQuotes();
$stock = "GOOG";
$stock = $price[$stock][1];

var_dump($price);
echo '<script>window.open("http://example.com/example?text=' . str_replace('"','',$stock) . '%20USD");</script>'

This solution opening a new window at my machine

Edit: for the format sl1 below solution will work:

$objYahooStock = new YahooStock;

$objYahooStock->addFormat("sl1");

$objYahooStock->addStock("GOOG");


$price = $objYahooStock->getQuotes();
$stock = "GOOG";
echo $stock = $price[$stock][1];

var_dump($price);
echo '<script>window.open("http://example.com/example?text=' . str_replace('\n','',trim($stock)) . '%20USD");</script>'
