从PHP中的函数回显多个字符串

Question

I have tried to create a function that will take two arguments and in theory, echo out the result. After doing some Googling, I got the impression that this should be accomplished using an array, however I'm not too sure on the logic.

I was hoping I could call the function like so - kb_article("How to do something", "Q12345"), to get the formatting of:

Related KB Article(s):
How to do something - Q12345

    function kb_article($title, $code)
{
    echo "<h2>Related KB Article(s): </h2><br />";
    echo $title + " - " + $code;
}

How can this be achieved?

Answer 1

String concatenation is performed using . ( instead of + ). Here's the corrected version of your function:

function kb_article($title, $code)
{
    echo '<h2>Related KB Article(s):</h2><br />';
    echo $title . " - " . $code;
}
