限制foreach循环中的输出

Question

I have a multidimensional array, called $alternative, which contains words.

This array is dynamically generated, sometimes there may only be 3 words, other times there could be 300 words.

In the below code, I am outputting the words from the array to the webpage.

How could I limit the output to say, 10 words?

foreach ($alternative as $test)
    {
        foreach ($test as $test2)
        {
        $test3 = ucwords($test2); //Capitalizes first letter of each word
        printf('<li><a href="related.php?query=%1$s" title="%1$s" >%1$s</a></li>', $test3);

        }

    }

At the moment, on certain occasions, too many words are being displayed, and I would like to limit it to ten words.

I cannot think of a way to do this. Does anybody have any suggestions?

Thanks guys.

Answer 1

$counter = 0;
foreach ($alternative as $test) {
    foreach ($test as $test2) {
        $test3 = ucwords($test2); //Capitalizes first letter of each word
        printf('<li><a href="related.php?query=%1$s" title="%1$s" >%1$s</a></li>', $test3);

        if (++$counter > 10) {
            break 2;
        }
    }
}
