如何在echo的html内容中进行echo工作

Question

I am here in search for a new method. I have defined the value of $SHOW_REALTIME_DATA_BUTTON_LABEL in another php file like this:

english.php(file name)

define("SHOW_REALTIME_DATA_BUTTON_LABEL","Select realtime data");

...and I want to display that value in another file inside the echo statement like this:

echo '<a  class="'.$class1.'" href="'.$link1.'"><span>'.$SHOW_REALTIME_DATA_BUTTON_LABEL.'</span></a> <br>';

In brief, I have to echo the value 'Select realtime data' in between spans.

Simply remove $ from it. This is what you should have:

echo '<a  class="'.$class1.'" href="'.$link1.'">
<span>'.SHOW_REALTIME_DATA_BUTTON_LABEL.'</span></a> <br>';

See the docs for more info.
