Closed. This question needs details or clarity. It is not currently accepting answers.

Answer

Solution:

You probably want to exclude space and @:

$string = preg_replace('#@([^\s@]+)#', '<b><a href="$1"> @$1 </a></b>', $string);

Answer

Solution:

Try this

$atPosition = stripos($string, '@');
$substr = '';
if (stripos($string, '@') !== false) {
    $substr = substr($string, $atPosition + 1);
    $content = '<b><a href="'.$substr.'"> '.$substr.' </a></b>';
}

echo $content;
