EMOJI[:lol]

in src can anybody tell me how should i use it ?

case ":lol":
    echo "<img src='EMOJI[:lol]' width='32' height='32'>";
break;

Answer 1

You have to escape quotes here. You can use like this:

echo "<img src='".EMOJI[':lol']."' width='32' height='32'>";

Answer 2

就像这样：

echo "<img src='" . EMOJI[':lol'] . "' width='32' height='32'>";

Answer 3

Array key should be integer or string so you should use EMOJI[':lol'] instead of EMOJI[:lol] ;

Example

case ":lol":
    echo "<img src='".EMOJI[':lol']."' width='32' height='32'>";
break;
