How to replace Microsoft-encoded quotes in PHP

Related searches

I need to replace Microsoft Word's version of single and double quotations marks (" " ‘ ’) with regular quotes (' and ") due to an encoding issue in my application. I do not need them to be HTML entities and I cannot change my database schema.

I have two options: to use either a regular expression or an associated array.

Is there a better way to do this?


Considering you only want to replace a few specific and well identified characters, I would go for str_replace with an array: you obviously don't need the heavy artillery regex will bring you ;-)

And if you encounter some other special characters (damn copy-paste from Microsoft Word...), you can just add them to that array whenever is necessary / whenever they are identified.

The best answer I can give to your comment is probably this link: Convert Smart Quotes with PHP

And the associated code (quoting that page):

function convert_smart_quotes($string) 
{ 
    $search = array(chr(145), 
                    chr(146), 
                    chr(147), 
                    chr(148), 
                    chr(151)); 

    $replace = array("'", 
                     "'", 
                     '"', 
                     '"', 
                     '-'); 

    return str_replace($search, $replace, $string); 
} 

(I don't have Microsoft Word on this computer, so I can't test by myself)

I don't remember exactly what we used at work (I was not the one having to deal with that kind of input), but it was the same kind of stuff...

Convert all types of smart quotes with PHP, I need to replace Microsoft Word version of single and double quotations marks ( “ ” ' ' ) with regular quotes (' and ") due to an encoding issue in my application. PHP Notice: iconv(): Detected an illegal character in input string in php shell code on line 1 You can change it to //IGNORE, which will remove the characters, but not translate them. This is the best way to replace Microsoft quotes encoded in CP1252. If they are in Unicode and you need to replace them, use Gumbo’s answer:


I have found an answer to this question. You need just one line of code using iconv() function in php:

// replace Microsoft Word version of single  and double quotations marks (" " ‘ ’) with  regular quotes (' and ")
$output = iconv('UTF-8', 'ASCII//TRANSLIT', $input);     

How to replace Microsoft-encoded quotes in PHP, these entities. If you want to decode instead (the reverse) you can use html_entity_decode(). ENT_QUOTES, Will convert both double and single quotes. Strings in PHP can be specified in four different ways: single quoted, double quoted, heredoc syntax and (since PHP 5.3.0) nowdoc syntax, the first two of them being by far the most frequently used. It is important to know the difference between using single quotes and double quotes.


Your Microsoft-encoded quotes are the probably the typographic quotation marks. You can simply replace them with str_replace if you know the encoding of the string in that you want to replace them.

Here’s an example for UTF-8 but using a single mapping array with strtr:

$quotes = array(
    "\xC2\xAB"     => '"', // « (U+00AB) in UTF-8
    "\xC2\xBB"     => '"', // » (U+00BB) in UTF-8
    "\xE2\x80\x98" => "'", // ‘ (U+2018) in UTF-8
    "\xE2\x80\x99" => "'", // ’ (U+2019) in UTF-8
    "\xE2\x80\x9A" => "'", // ‚ (U+201A) in UTF-8
    "\xE2\x80\x9B" => "'", // ‛ (U+201B) in UTF-8
    "\xE2\x80\x9C" => '"', // " (U+201C) in UTF-8
    "\xE2\x80\x9D" => '"', // " (U+201D) in UTF-8
    "\xE2\x80\x9E" => '"', // „ (U+201E) in UTF-8
    "\xE2\x80\x9F" => '"', // ‟ (U+201F) in UTF-8
    "\xE2\x80\xB9" => "'", // ‹ (U+2039) in UTF-8
    "\xE2\x80\xBA" => "'", // › (U+203A) in UTF-8
);
$str = strtr($str, $quotes);

If you’re need another encoding, you can use mb_convert_encoding to convert the keys.

If like me you arrive here with an enormous range of broken ASCII / Microsoft Word characters that are doing weird things to your CMS or RTE and iconv isn't working, then this mad function might just be for you.

Make sure your encoding is UTF-8 when you save this function to a file.

PHP Remove Curly (Smart) Quotes From String Data � Inteist, PHP Version: 4+ Changelog: The count parameter was added in PHP 5.0 Before PHP 4.3.3, this function experienced trouble when using arrays as both find and replace parameters, which caused empty find indexes to be skipped without advancing the internal pointer on the replace array. Newer versions will not have this problem.


We used the following. It deals with a few more special characters.

$text = str_replace(chr(130), ',', $text);    // Baseline single quote
$text = str_replace(chr(132), '"', $text);    // Baseline double quote
$text = str_replace(chr(133), '...', $text);  // Ellipsis
$text = str_replace(chr(145), "'", $text);    // Left single quote
$text = str_replace(chr(146), "'", $text);    // Right single quote
$text = str_replace(chr(147), '"', $text);    // Left double quote
$text = str_replace(chr(148), '"', $text);    // Right double quote

$text = mb_convert_encoding($text, 'HTML-ENTITIES', 'UTF-8');

The functions substr() and substr_replace() can be used when you want to extract or replace more than 1 character. Note: As of PHP 7.1.0, negative string offsets are also supported. These specify the offset from the end of the string.

Parameters. If search and replace are arrays, then str_replace() takes a value from each array and uses them to search and replace on subject.If replace has fewer values than search, then an empty string is used for the rest of replacement values.
