str_replace PHP不起作用

Question

I'm trying to replace certain characters with some other strings I got it to work on my main page with this exact code but on another page it wont work.

In the database i Got this ±1¢2£¥3§4£ as description2 In my php i use

$description2 = mysql_result($product, 0, 'productDescription2');

if ($description2 !=""){
$searchArray = array('±', '¢', '£', '¥', '§');
$replaceArray = array('x', 'x', 'x', 'x', 'x');
$teknisk =  str_replace($searchArray, $replaceArray, $description2);}

And as the output i use echo ''. $teknisk .''; echo ''. $teknisk .'';

But the result is this 1 2 3 4 (The same as the original description2 )

instead of x1x2xx3x4x

Please help!

Answer 1

Perhaps database uses different encoding than your PHP file. Start with comparing those strings converted with bin2hex() function (in PHP).

Answer 2

Second attempt:

There are a bunch of suggestions in the PHP doc's comments. Try these:

1. http://www.php.net/manual/es/function.str-replace.php#106653
2. http://www.php.net/manual/es/function.str-replace.php#75566
3. http://www.php.net/manual/es/function.str-replace.php#72344

Try explicitly setting your page's chartype. Try placing this in the header:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

Or, if you're using HTML 5:

<meta charset="utf-8">

Answer 3

我认为，由于您有一些奇怪的字符，它们可能超出了ascii的范围，并且您可能需要使用多字节字符串函数，尽管它没有str_replace类似物，所以您可能需要使用多字节正则表达式。
