How to escape “ and ” with php?
Question
I have a string which contains special quote characters (“”), among other characters which might need to be escaped in order to render correctly.
I tried using
htmlentities($string, ENT_QUOTES, "UTF-8")
However it doesn't seem to work on “ and ” . I should think that they would get turned into “ and ” , but they don't.
When they are not escaped in my html document, these characters render as in firefox.
Perhaps I have something wrong with my encoding settings, as they seem to be working fine in this post without being escaped..
Yet everything looks correct to me:
The
Content-Typeis set to UTF-8 in<head>:<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">According to
file, the document is saved asUTF-8:index.phtml: HTML document, UTF-8 Unicode text, with very long linesFirefox recognizes the file as
UTF-8.
However, straight “ and ”s don't render correctly, yet escaped versions ( “ and ” ) do.

This function converts “ and ” to " .
function convert_smart_quotes($string)
{
$search = array(chr(147), chr(148));
$replace = array('"', '"');
return str_replace($search, $replace, $string);
}
So after passing the string which contains “ or ” to this function it can be passed to
htmlentities($string, ENT_QUOTES, "UTF-8")
as in your case " render correctly in the browser, the string will be shown correctly.
Another method is to replace the string with “ and ”

$quoteLeft = ' “ ' ;
$quoteRight = ' ” ' ;
$utf = ''.$quoteLeft.'UTF-8'.$quoteRight.'';
htmlentities($string, ENT_QUOTES, $utf);

为了避免使用引号，请使用backslah \\因此，您的代码基本上看起来像htmlentities($string, ENT_QUOTES, \\"UTF-8\\")
