How can i remove only � (using curl To get data)
$str = "Check this out <a href=�http://www.somewebsite.com�>Somewebsite</a>, this is a great website
Windows� (XP 32bit/Vista/7/8/8.1)";
I just want � to be removed.
I tried
$output = preg_replace("/[^A-Za-z0-9]/","",$str);
it remove html also ... but i want html
Instead of doing a bad work-around like that, you should fix your charset issue instead. Your problem is likely that you don't use the same character-encoding in all levels of your application/scripts. Anything that has or can be set to a specific character-encoding, should be set to the same. The most general ones are below.
Save the document as UTF-8 (or UTF8 w/o BOM) (If you're using Notepad++, it's Format -> Convert to UFT-8 or UTF8 w/o BOM)
The header in both PHP and HTML should be set to UTF-8
HTML: <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />, inside the <head>-tag in your document.
PHP: header('Content-Type: text/html; charset=utf-8'); - PHP headers has to be set BEFORE any output is made (no HTML, no whitespace, no echo/print - nothing).
There are other aspects as well that might need to be set to UTF-8, it depends on what kind of PHP functions you are using and so on. But the above is generally a good start.

I have a problem of special character writing on my website coded in PHP (data from database and normal writing html)
Code :
code in Sublime text
Result :
result in web
I have in my header :
‹meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"›
It's important that your entire line code has the same charset to avoid issues where characters displays incorrectly.
There are quite a few settings that needs to be properly defined and I'd strongly recommend UTF-8, as this has most letters you would need (Scandinavian, Greek, Arabic).
Here's a little list of things that has to be set to a specific charset.
Headers
Setting the charset in both HTML and PHP headers to UTF-8
PHP: header('Content-Type: text/html; charset=utf-8');
(PHP headers has to be placed before any kind output (echo, whitespace, HTML))
HTML: <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
(HTML-headers are placed within the <head> / </head> tag)
File-encoding
It might also be needed for the file itself to be UTF-8 encoded. If you're using Notepad++ to write your code, this can be done in the "Format" drop-down on the taskbar. You should use UTF-8 w/o BOM (see this SO).
Other
Some specific functions have the attribute of a specific charset, and if you are using such functions, it should be specified there as well. Read the documentation for each function.
Should you follow all of the pointers above, chances are your problem will be solved. If not, you can take a look at this StackOverflow post: UTF-8 all the way through.
I work on a website that has different language interfaces, so far I use english and german.
when the german text is loaded, it shows weird characters like the following screenshot
though I use
header('Content-type: text/html; charset=utf-8');
and also in the html header
<META http-equiv="content-type" content="text/html; charset=utf-8">
what else can I do to solve it ?
Thanks
The content of the page needs to also be in UTF-8. Your content was probably made using MS Word, which uses Windows 1251 encoding. You need to re-save your document as UTF-8.
UTF-8 does not convert formats for you.
If those strings are saved in a file, the file has to be encoded in UTF-8 too.
If you're getting them from a database, they'll have to be stored as UTF-8 and you'll have to set the connection charset to utf-8.
You could also check whether your text is UTF-8 and if not, convert it with utf8_encode.
I am new here, so I apologize if I am doing anything wrong.
I have a form which submits user input onto another page. User is expected to type ä, ö, é, etc... I have placed all of the following in the document:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
header('Content-Type:text/html; charset=UTF-8');
<form action="whatever.php" accept-charset="UTF-8">
I even tried:
ini_set('default_charset', 'UTF-8');
When the other page loads, I need to check what the user input with something like:
if ( $_POST['field'] == $check ) {
...
}
But if he inputs something like 'München', PHP will compare 'München' with 'München' and will never trigger TRUE even though it should. Since it is specified UTF-8 everywhere, I am guessing that the server is converting to something else (Windows-1252 as I read on another thread) because it does not support or is not configured to UTF-8. I am using Apache on a local server before I load into production; I have not changed (and don't know how to) any of the default settings. I've been working on a Windows 7, editing with Notepad++ enconding my files in ANSI. If I bin2hex('München') I get '4dc3bc6e6368656e'.
If I echo $_POST['field']; it displays 'München' correctly.
I have researched everywhere for an explanation, all I find is that I should include those tags/headings I already have.
Any help is much appreciated.
You are facing many different problems at the same, let's start with the simplest one.
Problem 1) You say that echo $_POST['field']; will display it correctly? What do you mean with "display"? It can be displayed correctly in two cases:
either the field is in UTF-8 and your page has been declared as UTF-8 and the browser is displaying it as UTF-8 or,
the field is in Latin-1 and the browser has decided (through the auto-detection heuristics) that your page is in Latin-1.
So, the fact that echo $_POST['field']; is correct tells you nothing.
Problem 2) You are using
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
header('Content-Type:text/html; charset=UTF-8');
Is this PHP code? If it is, it will be an error because the header must be set before sending out any byte. If you do this you will not set the Content-Type header and PHP should generate a warning.
Problem 3) You are using
<form action="whatever.php" accept-charset="UTF-8">
Some browsers (IE, mostly) ignore accept-charset if they can coerce the data to be sent in ASCII or ISO Latin-1. So the data will be in UTF-8 and declared as ISO Latin-1 or ISO Latin-1 and sent as ISO Latin-1 (but this second case is not your case).
Have a look at https://stackoverflow.com/a/8547004/449288 to see how to solve this problem.
Problem 4) Which strings are you comparing? For example, if you have
$city = "München"
$_POST['city'] == $city
The result of this code will depend on the encoding of the PHP file. If the file is encoded in ISO Latin-1 and the $_POST correctly contains UTF-8 data, the == will compare different bytes and will return false.
Another solution that may be helpful is in Apache, you can place a directive in your configuration file (httpd.conf) or .htacess called AddDefaultCharset. It looks like this:
AddDefaultCharset utf-8
http://httpd.apache.org/docs/2.0/mod/core.html#adddefaultcharset
That will override any other default charsets.
I changed "mbstring.detect_order = pass" in my php.ini file and i worked
I've used Unicode characters in my forms and file many times. I had not any problem up to now.
Try to do these steps and check the result:
Remove header('Content-Type:text/html; charset=UTF-8'); from your HTML form codes.
Use your form just like <form action="whatever.php"> without accept-charset="UTF-8". (It's better to insert the method of sending data in your form tag).
In target page (whatever.php), insert again <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> in a <head> tag.
I always did my project like what I mentioned here and I did not have any problem with Unicode strings.
This is due to the character encoding of the PHP file(s).
The hardcoded München is stored with the character encoding of the source file(s), in this case ANSI and when that value is compared to the UTF-8 encoded value provided in the $_POST variable, the two will, quite naturally, differ.
The solution to your problem is one of:
Serve and process content with the same encoding as that of the source file(s), in this case likely to be windows-1252.
This would, for starters, include changing the content="text/html; charset=UTF-8" to content="text/html; charset=windows-1252" whenever serving HTML data.
Avoid all hardcoded values that could be affected by character encoding issues between UTF-8 and windows-1252, more or less only hardcode values that only includes English letters and numbers.
Any UTF-8 values would have to be read from a source that ensures they are UTF-8 encoded (for instance a database set to use UTF-8 as storage encoding as well as connection encoding).
Wrap all hardcoded assignments in utf8_encode(), for instance $value = utf8_encode ('München');
Change the encoding of the source file(s) to UTF-8.
This can be accomplished in any number of ways, a decent text editor will be able to do it or the outstanding libiconv can be used, especially for batch processing.
Either solution 1 or 4 would be my preferred solution, especially if multiple people are involved in the project.
As a side-note, some text editors (notably Notepad++) has the option of using either UTF-8 or UTF-8 without BOM. The BOM (Byte Order Mark) is pointless in UTF-8 and will cause problems when writing headers in PHP (most often when doing a redirect). This is because the BOM is right in front of the initial <?php, causing the server to send the BOM just as it would had there been any other character in front. The difference is you'd note a character in front, but the BOM isn't displayed.
Rule of thumb: Always use UTF-8 without BOM.
I have a PHP file which has the following text:
<div class="small_italic">This is what you´ll use</div>
On one server, it appears as:
This is what you´ll use
And on another, as:
This is what you�ll use
Why would there be a difference and what can I do to make it appear properly (as an apostrophe)?
Note to all (for future reference)
I implemented Gordon's / Gumbo's suggestion, except I implemented it on a server level rather than the application level. Note that (a) I had to restart the Apache server and more importantly, (b) I had to replace the existing "bad data" with the corrected data in the right encoding.
/etc/php.ini
default_charset = "iso-8859-1"
You have to make sure the content is served with the proper character set:
Either send the content with a header that includes
<?php header("Content-Type: text/html; charset=[your charset]"); ?>
or - if the HTTP charset headers don't exist - insert a <META> element into the <head>:
<meta http-equiv="Content-Type" content="text/html; charset=[your charset]" />
Like the attribute name suggests, http-equiv is the equivalent of an HTTP response header and user agents should use them in case the corresponding HTTP headers are not set.
Like Hannes already suggested in the comments to the question, you can look at the headers returned by your webserver to see which encoding it serves. There is likely a discrepancy between the two servers. So change the [your charset] part above to that of the "working" server.
For a more elaborate explanation about the why, see Gumbo's answer.
The display of the REPLACEMENT CHARACTER � (U+FFFD) most likely means that you’re specifying your output to be Unicode but your data isn’t.
In this case, if the ACUTE ACCENT ´ is for example encoded using ISO 8859-1, it’s encoded with the byte sequence 0xB4 as that’s the code point of that character in ISO 8859-1. But that byte sequence is illegal in a Unicode encoding like UTF-8. In that case the replacement character U+FFFD is shown.
So to fix this, make sure that you’re specifying the character encoding properly according to your actual one (or vice versa).
To sum it maybe up a little bit:
Make sure the FILE saved on the web server has the right encoding
Make sure the web server also delivers it with the right encoding
Make sure the HTML meta tags is set to the right encoding
Make sure to use "standard" special chars, i.e. use the ' instead of ´of you want to write something like "Luke Skywalker's code"
For encoding, UTF-8 might be good for you.

The simple solution is to use ASCII code for special characters.
The value of the apostrophe character in ASCII is ’. Try putting this value in your HTML, and it should work properly for you.
Set your browser's character set to a defined value:
For example,
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
This is probably being caused by the data you're inserting into the page with PHP being in a different character encoding from the page itself (the most common iteration is one being Latin 1 and the other UTF-8).
Check the encoding being used for the page, and for your database. Chances are there will be a mismatch.
Create an .htaccess file in the root directory:
AddDefaultCharset utf-8
AddCharset utf-8 *
<IfModule mod_charset.c>
CharsetSourceEnc utf-8
CharsetDefault utf-8
</IfModule>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
I'm using Kohana 3, which has full support for Unicode.
I have this as the first child of my <head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
The Unicode character I am inserting into is é as in Café.
However, I am getting the triangle with a ? (as in could not decode character).
As far as I can tell in my own code, I am not doing any string manipulation on the text.
In fact, I have placed the accent straight into a view's PHP file and it is still not working.
I copied the character from this page: http://www.fileformat.info/info/unicode/char/00e9/index.htm
I've only just started examining PHP's Unicode limitations, so I could be doing something horribly wrong.
So, how do I display this character? Do I need to resort to the HTML entity?
Update
So this works
Caf<?php echo html_entity_decode('é', ENT_NOQUOTES, 'UTF-8'); ?>
Why does that work? If I copy the output accented e from that script and insert it into my document, it doesn't work.
View the http headers. You should see something like
Content-Type: text/html; charset=UTF-8
Browsers don't pay much attention to meta tags, if there was a real http header stating a different encoding.
update
Whatcha get from this?
echo bin2hex('é');
echo chr(0xc3) . chr(0xa9);
You should get c3a9é, otherwise I'd say file encoding issue.
I guess, you see �, the replacement character for invalid UTF-8 byte sequences. Your text is not UTF-8 encoded. Check your editor’s settings to control the encoding of the PHP file.
If you’re not sure about the encoding of your sources, you can enforce UTF-8 compatibilty as described here (German text): Force UTF-8.
You should never need entities except the basic ones.
