PHP：访问存储在函数中的变量

Question

I have a set of PHP variables (that start with $cta). I use a PHP 'If' test, to change the values of these variables depending on the values of other variables.

I use these variables in several locations in my PHP file (and wrap the variables in different HTML code depending on the location), so I want to store the 'If' testing code in a function.

That way, my code will be more efficient, as the 'If' test will be in one place.

Here is my function:

function calltoaction {

 if ($cta_settings == 'cta_main') {
                $cta_prompt = 'We are ready for your call';
                $cta_button = 'Contact Us';
            }
($cta_settings == 'cta_secondary') {
                $cta_prompt = 'Call us for fast professional service';
                $cta_button = 'Call Us';
            }
}

Now that I have the function, how do I access the $cta variables inside of it?

E.g. The following doesn't work:

<?php 
calltoaction();
print '<p>' . $cta_prompt . '</p>;
print '<span>' . $cta_button . '</span>;
?>

(The examples presented above are a cut down version, my full code is a bit more complex).

Answer 1

Perhaps you wanted to do something like this:

<?php
function callToAction($cta_settings)
{

    if ($cta_settings == 'cta_main') {
        $cta_prompt = 'We are ready for your call';
        $cta_button = 'Contact Us';
    } elseif ($cta_settings == 'cta_secondary') {
        $cta_prompt = 'Call us for fast professional service';
        $cta_button = 'Call Us';
    } else {
        $cta_prompt = 'Call us for fast professional service';
        $cta_button = 'Call Us';
    }
    return ["cta_prompt" => $cta_prompt, "cta_button" => $cta_button];
}

$cta1 = callToAction('cta_main');
?>

<p><?php echo $cta1['cta_prompt']; ?></p>
<span><?php echo $cta1['cta_button']; ?></span>
