Quote not displaying properly

So the characters “ and ” (“ and ” respectively) are variations of the neutral quote ("). I see them in a data sheet开发者_如何学Go I have that is full of html and am trying to find and replace them using php.

First, I am testing to see how to reproduce it. Here is my php code:

<?php
echo chr(8220);
?>

Why doesn't this work? I have tried other numbers in the char() function and it worked fine. I have tried setting the character set to UTF-8 and ISO-8859-1 but it didn't work. How do I make this echo the quote?

I am trying to echo it because I am trying to integrate it into the php code. I know I can just copy and paste it but that will be too confusing to me.

Try:

$str = str_replace(chr(147), '"', $str);    // left double quote
$str = str_replace(chr(148), '"', $str);    // right double quote

Where 147 and 148 respectively equal left and right double quotes.

chr() will output only ASCII characters. Use echo chr(34). 34 is decimal number for double quote in ASCII table. There is only 128 (0-127) characters in standard ASCII table. PHP support extended ASCII with 256 characters.

Have you tried the function mb_convert_encoding?

See this explanation on the php docs for how to get the character from its html encoding. Here is the function that that person defined (directly copied from that link):

function unichr($u) {
    return mb_convert_encoding('&#' . intval($u) . ';', 'UTF-8', 'HTML-ENTITIES');
}

Try charset=WINDOWS-1252"
