How can I save UTF-8 character(Malayalam language) to the MySQL database as HTML entity using PHP. I have tried some of the php functions to do the same still I am not able to make it. So it will be helpful if someone point me in the right direction.
Here is what I've done:
Set the field collation to 'utf-8_general_ci'.
Set the content-type to utf-8 in the page header.
Used php function htmlentities() and
htmlspecialchars().
Create/change your table collation = utf-8, set names to utf-8 http://dev.mysql.com/doc/refman/5.0/en//charset-connection.html
also use utf-8 internally on your server and declare your website utf-8 with the appropriate tags
At last I got the solution myself :)
There is a php function to convert the characters to HTML entity.
mb_convert_encoding("$SPECIAL_CHAR",'HTML-ENTITIES', 'UTF-8');
I'm having an issue that i believe is related to unicode text. When the user enters a string that has the unicode bullet character, mysql is not able to save that field (the rest of the update query works though). Here's how i've been trying to deal with it.
$str = "· Close up the server";
$str = preg_replace("\u2022", "•", $str);
...however this is still not working.
So many things can go wrong here, because database, form submits and source code string literals are all involved. I'll assume you want to use UTF-8, because with any other typical encoding (CP1252, Latin1) you'll be screwed when you want to use json_ or accept more than ~200 different characters.
The first thing to do is remove any kind of conversion etc code that was written with the intention of trying to fix encoding issues. Such as utf8_encode, htmlentitites, *_replace.. whatever.
Source encoding.
$str = "· Close up the server";
When writing the above, the PHP source file needs to be physically encoded in UTF-8. If you are on Windows, you must explicitly do or configure this. UTF-8 doesn't happen magically on Windows.
Form submits
When user submits a form, the payload will be in whatever encoding you declared the page to be. You can declare it like so:
header("Content-Type: text/html; charset=utf-8");
But anyone can actually submit arbitrary bytes to your server, so you should validate the input is in UTF-8 before proceeding. mb_check_encoding is good.
Database
Since at this point your data is coming in as UTF-8, your input strings are in UTF-8. You must specify this after connecting to the database, by specifying a connection encoding.
mysql_set_charset("utf8"); //After making the connection, and before any queries
//or $mysqli->set_charset( "utf8");
This makes the database read your input in UTF-8, and encode its output in UTF-8. You would also want to set your columns/tables/databases to UTF-8 as well.
Unicode escape sequences \uxxxx or \uhhhh\ullll or \Uxxxxxxxx are not supported in PHP.
\u2022 is the UTF-16 hex encoding for "Bullet". Not UTF-8.
You might also want to SET NAMES 'UTF-8'; or change charset before you open your database.
I have some texts in French (containing accented characters such as "é"), stored in a MySQL table whose collation is utf8_unicode_ci (both the table and the columns), that I want to output on an HTML5 page.
The HTML page charset is UTF-8 (< meta charset="utf-8" />) and the PHP files themselves are encoded as "UTF-8 without BOM" (I use Notepad++ on Windows). I use PHP5 to request the database and generate the HTML.
However, on the output page, the special characters (such as "é") appear garbled and are replaced by "�".
When I browse the database (via phpMyAdmin) those same accented characters display just fine.
What am I missing here?
(Note: changing the page encoding (through Firefox's "web developer" menu) to ISO-8859-1 solves the problem... except for the special characters that appears directly in the PHP files, which become now corrupted. But anyway, I'd rather understand why it doesn't work as UTF-8 than changing the encoding without understanding why it works. ^^;)
I experienced that same problem before, and what I did are the following
1) Use notepad++(can almost adapt on any encoding) or eclipse and be sure in to save or open it in UTF-8 without BOM.
2) set the encoding in PHP header, using header('Content-type: text/html; charset=UTF-8');
3) remove any extra spaces on the start and end of my PHP files.
4) set all my table and columns encoding to utf8mb4_general_ci or utf8mb4_unicode_ci via PhpMyAdmin or any mySQL client you have. A comparison of the two encodings are available here
5) set mysql connection charset to UTF-8 (I use PDO for my database connection )
PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"
PDO::MYSQL_ATTR_INIT_COMMAND => "SET CHARACTER SET utf8"
or just execute the SQL queries before fetching any data
6) use a meta tag <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
7) use a certain language code for French
<meta http-equiv="Content-language" content="fr" />
8) change the html element lang attribute to the desired language
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="fr" lang="fr">
and will be updating this more because I really had a hard time solving this problem before because I was dealing with Japanese characters in my past projects
9) Some fonts are not available in the client PC, you need to use Google fonts to include it on your CSS
10) Don't end your PHP source file with ?>
NOTE:
but if everything I said above doesn't work, try to adjust your encoding depending on the character-set you really want to display, for me I set everything to SHIFT-JIS to display all my japanese characters and it really works fine. But using UFT-8 must be your priority
This works for me
Make your database utf8_general_ci
Save your files in N++ as UTF-8 without BOM
Put $mysqli->query('SET NAMES utf8'); after the connection to the database in your PHP file
Put < meta charset="utf-8" /> in your HTML-s
Works perfect.
If your php.ini default_charset is not set to UTF-8, you need to use a Content-type to define your data. Apply the following header at the top of your file(s) :
header("Content-type: text/html; charset=utf-8");
If you have still troubles with encoding, the cause may be one of the following:
a database server charset problem (check encoding of your server)
a database client charset problem (check encoding of your connection)
a database table charset problem (check encoding of your table)
a php default encoding problem (check default_encoding parameter in parameters.ini)
a multibyte missconfigured (see mb_string parameters in parameters.ini)
a <form> charset problem (check that it is sent as utf-8)
a <html> charset problem (where no enctype is set in your html file)
a Content-encoding: problem (where the wrong encoding is sent by Apache).
SET NAMES worked for me.
My issue was in one of my editing pages the field with the foreign characters would not display, on the production web pages there was no problem.
I know you already have an answer. That's great. But strangely none of these answers solved my issue. I'd like to share my answer for the benefit of the others who may encounter the same issues.
I also had the same problems as the OP, with regards to French accents in a multi-lingual application.
But I encountered this issue for the first time when I had to pass (French accented) data as segments in AJAX calls.
Yes, we must have the database set to work with UTF8. But the fact that AJAX calls had query strings (in my case segments, since I'm using CodeIgniter), I had to simply encode the French text.
To do this on the client-side, use the Javascript encodeURI() function with your data.
And to reverse it in PHP, just use urldecode($MyStr) where data was received as parameters.
Hope this helps.
Type something full French signs in your (php) file
Save that file as UTF-8
Paste line beneath into your website header
header('Content-Type: text/html; charset=utf-8');
Page (file) should look good.
If looks good go here for mysql behavior after (SET_NAMES).
So I have programmed a crawler to scrape information and data from a website with charset utf8. But when I tried to store the contents into MySQL, some special characters, such as Spanish letters), did not show correctly in MySQL.
Here is what I have done:
Put header("Content-Type: text/html; charset=utf-8") in PHP
Set all charset in MySQL into utf8-unicode-ci
Have $conn->query("SET NAMES 'utf8'") this upon connection
Double checked that the html I parsed was encoded in utf-8
So what are some potentially problems here?
Maybe you coded your crawler using functions which are not supposed to manage multi-byte characters.
For example strlen instead of mb_strlen.
Try putting:
mb_internal_encoding("UTF-8");
as first line of your php coce, and then check if you have to convert some functions in their respective mb version.
Have a look at multibyte string reference
As a last chance you may play with iconv function just before inserting the string into mysql.
Something as:
$utf8_string = iconv(iconv_get_encoding($string), "UTF-8", $string);
should do the trick
Start by checking if the data is stored wrong in the database, in which case the problem is with your crawler. Otherwise the problem is in your presentation.
To test this, I would suggest that you use a dedicated mysql client (Such as the command line client) to inspect data.
I remember pulling my hair out in dealing with UTF8 issues until I started adding this to my header:
setlocale(LC_ALL, 'en_US.UTF-8');
I'm writing a php program that pulls from a database source. Some of the varchars have quotes that are displaying as black diamonds with a question mark in them (�, REPLACEMENT CHARACTER, I assume from Microsoft Word text).
How can I use php to strip these characters out?
If you see that character (� U+FFFD "REPLACEMENT CHARACTER") it usually means that the text itself is encoded in some form of single byte encoding but interpreted in one of the unicode encodings (UTF8 or UTF16).
If it were the other way around it would (usually) look something like this: ä.
Probably the original encoding is ISO-8859-1, also known as Latin-1. You can check this without having to change your script: Browsers give you the option to re-interpret a page in a different encoding -- in Firefox use "View" -> "Character Encoding".
To make the browser use the correct encoding, add an HTTP header like this:
header("Content-Type: text/html; charset=ISO-8859-1");
or put the encoding in a meta tag:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
Alternatively you could try to read from the database in another encoding (UTF-8, preferably) or convert the text with iconv().
I also faced this � issue. Meanwhile I ran into three cases where it happened:
substr()
I was using substr() on a UTF8 string which cut UTF8 characters, thus the cut chars could not be displayed correctly. Use mb_substr($utfstring, 0, 10, 'utf-8'); instead. Credits
htmlspecialchars()
Another problem was using htmlspecialchars() on a UTF8 string. The fix is to use: htmlspecialchars($utfstring, ENT_QUOTES, 'UTF-8');
preg_replace()
Lastly I found out that preg_replace() can lead to problems with UTF. The code $string = preg_replace('/[^A-Za-z0-9ÄäÜüÖöß]/', ' ', $string); for example transformed the UTF string "F(×)=2×-3" into "F � 2� ". The fix is to use mb_ereg_replace() instead.
I hope this additional information will help to get rid of such problems.
This is a charset issue. As such, it can have gone wrong on many different levels, but most likely, the strings in your database are utf-8 encoded, and you are presenting them as iso-8859-1. Or the other way around.
The proper way to fix this problem, is to get your character-sets straight. The simplest strategy, since you're using PHP, is to use iso-8859-1 throughout your application. To do this, you must ensure that:
All PHP source-files are saved as iso-8859-1 (Not to be confused with cp-1252).
Your web-server is configured to serve files with charset=iso-8859-1
Alternatively, you can override the webservers settings from within the PHP-document, using header.
In addition, you may insert a meta-tag in you HTML, that specifies the same thing, but this isn't strictly needed.
You may also specify the accept-charset attribute on your <form> elements.
Database tables are defined with encoding as latin1
The database connection between PHP to and database is set to latin1
If you already have data in your database, you should be aware that they are probably messed up already. If you are not already in production phase, just wipe it all and start over. Otherwise you'll have to do some data cleanup.
A note on meta-tags, since everybody misunderstands what they are:
When a web-server serves a file (A HTML-document), it sends some information, that isn't presented directly in the browser. This is known as HTTP-headers. One such header, is the Content-Type header, which specifies the mimetype of the file (Eg. text/html) as well as the encoding (aka charset).
While most webservers will send a Content-Type header with charset info, it's optional. If it isn't present, the browser will instead interpret any meta-tags with http-equiv="Content-Type". It's important to realise that the meta-tag is only interpreted if the webserver doesn't send the header. In practice this means that it's only used if the page is saved to disk and then opened from there.
This page has a very good explanation of these things.
As mentioned in earlier answers, it is happening because your text has been written to the database in iso-8859-1 encoding, or any other format.
So you just need to convert the data to utf8 before outputting it.
$text = “string from database”;
$text = utf8_encode($text);
echo $text;
To make sure your MYSQL connection is set to UTF-8 (or latin1, depending on what you're using), you can do this to:
$con = mysql_connect("localhost","username","password");
mysql_set_charset('utf8',$con);
or use this to check what charset you are using:
$con = mysql_connect("localhost","username","password");
$charset = mysql_client_encoding($con);
echo "The current character set is: $charset\n";
More info here: http://php.net/manual/en/function.mysql-set-charset.php
I chose to strip these characters out of the string by doing this -
ini_set('mbstring.substitute_character', "none");
$text= mb_convert_encoding($text, 'UTF-8', 'UTF-8');
Just Paste This Code In Starting to The Top of Page.
<?php
header("Content-Type: text/html; charset=ISO-8859-1");
?>
Based on your description of the problem, the data in your database is almost certainly encoded as Windows-1252, and your page is almost certainly being served as ISO-8859-1. These two character sets are equivalent except that Windows-1252 has 16 extra characters which are not present in ISO-8859-1, including left and right curly quotes.
Assuming my analysis is correct, the simplest solution is to serve your page as Windows-1252. This will work because all characters that are in ISO-8859-1 are also in Windows-1252. In PHP you can change the encoding as follows:
header('Content-Type: text/html; charset=Windows-1252');
However, you really should check what character encoding you are using in your HTML files and the contents of your database, and take care to be consistent, or convert properly where this is not possible.
Add this function to your variables
utf8_encode($your variable);
Try This Please
mb_substr($description, 0, 490, "UTF-8");
This will help you. Put this inside <head> tag
<meta charset="iso-8859-1">
That can be caused by unicode or other charset mismatch. Try changing charset in your browser, in of the settings the text will look OK. Then it's question of how to convert your database contents to charset you use for displaying. (Which can actually be just adding utf-8 charset statement to your output.)
what I ended up doing in the end after I fixed my tables was to back it up and change back the settings to utf-8 then I altered my dump file so that DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci are my character set entries
now I don't have characterset issues anymore because the database and browser are utf8.
I figured out what caused it. It was the web page+browser effects on the DB. On the terminals that are linux (ubuntu+firefox) it was encoding the database in latin1 which is what the tabes are set. But on the windows 10+edge terminals, the entries were force coded into utf8. Also I noticed the windows 10 has issues staying with latin1 so I decided to bend with the wind and convert all to utf8.
I figured it was a windows 10 issue because we started using win 10 terminals.
so yet again microsoft bugs causes issues. I still don't know why the encoding changes on the forms because the browser in windows 10 shows the latin1 characterset but when it goes in its utf8 encoded and I get the data anomaly. but in linux+firefox it doesn't do that.
This happened to work in my case:
$text = utf8_decode($text)
I turns the black diamond character into a question mark so you can:
$text = str_replace('?', '', utf8_decode($text));
Just add these lines before headers.
Accurate format of .doc/docx files will be retrieved:
if(ini_get('zlib.output_compression'))
ini_set('zlib.output_compression', 'Off');
ob_clean();
When you extract data from anywhere you should use functions with the prefix md_FUNC_NAME.
Had the same problem it helped me out.
Or you can find the code of this symbol and use regexp to delete these symbols.
You can also change the caracter set in your browser. Just for debug reasons.
Using the same charset (as suggested here) in both the database and the HTML has not worked for me... So remembering that the code is generated as HTML, I chose to use the "(HTML code) or the " (ISO Latin-1 code) in my database text where quotes were used. This solved the problem while providing me a quotation mark. It is odd to note that prior to this solution, only some of the quotation marks and apostrophes did not display correctly while others did, however, the special code did work in all instances.
I ran the "detect encoding" code after my collation change in phpmyadmin and now it comes up as Latin_1.
but here is something I came across looking a different data anomaly in my application and how I fixed it:
I just imported a table that has mixed encoding (with diamond question marks in some lines, and all were in the same column.) so here is my fix code. I used utf8_decode process that takes the undefined placeholder and assigns a plain question mark in the place of the "diamond question mark " then I used str_replace to replace the question mark with a space between quotes.
here is the
[code]
include 'dbconnectfile.php';
//// the variable $db comes from my db connect file
/// inx is my auto increment column
/// broke_column is the column I need to fix
$qwy = "select inx,broke_column from Table ";
$res = $db->query($qwy);
while ($data = $res->fetch_row()) {
for ($m=0; $m<$res->field_count; $m++) {
if ($m==0){
$id=0;
$id=$data[$m];
echo $id;
}else if ($m==1){
$fix=0;
$fix=$data[$m];
$fix = utf8_decode($fix);
$fixx =str_replace("?"," ",$fix);
echo $fixx;
////I echoed the data to the screen because I like to see something as I execute it :)
}
}
$insert= "UPDATE Table SET broke_column='".$fixx."' where inx='".$id."'";
$insresult= $db->query($insert);
echo"<br>";
}
?>
For global purposes.
Instead of converting, codifying, decodifying each text I prefer to let them as they are and instead change the server php settings.
So,
Let the diamonds
From the browser, on the view menu select
"text encoding" and find the one which let's you see your text
correctly.
Edit your php.ini and add:
default_charset = "ISO-8859-1"
or instead of ISO-8859 the one which fits your text encoding.
Go to your phpmyadmin and select your database and just increase the length/value of that table's field to 500 or 1000 it will solve your problem.
