The following are:
$a = ' 2<span><nobr>tóng<span class= ' h ' >dòng</span></nobr><br> dong </span>3 ' ;
echo preg_replace ('/<span class= "h" >[^<]*?</span>/', ", $a);
Will prompt:
Warning:preg_replace (): Unknown modifier ' P ' in e:phplearntest.php on line 12
The reason is:
In regular mode, use/do delimiters, but also include/in regular, so this error occurs, PHP mistakenly when the next </span> in the trailing slash is the end of the delimiter.
Solution:
1, plus an escape character:
echo preg_replace ('/<span class= "h" >[^<]*?</span>/', ", $a);
2. Change other delimiters:
Echo preg_replace (' {<span class= "H" >[^<]*?</span>} ', ', $a);
