I am passing my message to SMS api,
This is the documentation
Normally Unicode Messages are Arabic and Chinese Message, which are
defined by GSM Standards. Unicode messages are nothing but normal text
type messages but it has to be submitted in HEX form. To submit
Unicode messages following Url to be used.
I tried bin2hex() there is not working for the output.
$str = '人';
//$str = 'a';
$output = bin2hex($str);
echo $output;
//output
//人 = e4baba ； I would expect '4EBA'
I found a similar solution but it is in VB.net anyone can convert it?

the sample i had tried, and it is work:-
example of conversion : a converted to hexadecimal is 0061, 人 converted to hexadecimal is 4EBA
The issue you are facing has to do with encoding. Since these are considered special characters, you need to add some encoding details when converting to hex.
Each of these outputs exactly what you were looking for when I run them:
echo bin2hex(iconv('UTF-8', 'ISO-10646-UCS-2', '人')) . PHP_EOL;
//Outputs 4eba
echo bin2hex(iconv('UTF-8', 'UNICODE-1-1', '人')) . PHP_EOL;
//Outputs 4eba
echo bin2hex(iconv('UTF-8', 'UTF-16BE', '人')) . PHP_EOL;
//Outputs 4eba
Pick whichever one you fancy.
If you want to convert back:
echo iconv('UTF-16BE', 'UTF-8', hex2bin('4eba')) . PHP_EOL;
//outputs 人

I am making a dynamic Unicode icon in PHP. I want the UTF-8 code of the Unicode icon.
So far I have done:
$value = "1F600";
$emoIcon = "\u{$value}";
$emoIcon = preg_replace("/\\\\u([0-9A-F]{2,5})/i", "&#x$1;", $emoIcon);
echo $emoIcon; //output 😀
$hex=bin2hex($emoIcon);
echo $hex; // output 26237831463630303b
$hexVal=chunk_split($hex,2,"\\x");
var_dump($hexVal); // output 26\x23\x78\x31\x46\x36\x30\x30\x3b\x
$result= "\\x" . substr($hexVal,0,-2);
var_dump($result); // output \x26\x23\x78\x31\x46\x36\x30\x30\x3b
But when I put the value directly, it prints the correct data:
$emoIcon = "\u{1F600}";
$emoIcon = preg_replace("/\\\\u([0-9A-F]{2,5})/i", "&#x$1;", $emoIcon);
echo $emoIcon; //output 😀
$hex=bin2hex($emoIcon);
echo $hex; // output f09f9880
$hexVal=chunk_split($hex,2,"\\x");
var_dump($hexVal); // output f0\x9f\x98\x80\x
$result= "\\x" . substr($hexVal,0,-2);
var_dump($result); // output \xf0\x9f\x98\x80
\u{1F600} is a Unicode escape sequence used in double-quoted strings, it must have a literal value - trying to use "\u{$value}", as you've seen, doesn't work (for a couple reasons, but that doesn't matter so much.)
If you want to start with "1F600" and end up with 😀 use hexdec to turn it into an integer and feed that to IntlChar::chr to encode that code point as UTF-8. E.g.:
$value = "1F600";
echo IntlChar::chr(hexdec($value));
Outputs:
😀
Since some days I read about Character-Encoding, I want to make all my Pages with UTF-8 for Compability. But I get stuck when I try to convert User-Input to UTF-8, this works on all Browsers, expect Internet-Explorer (like always).
I don't know whats wrong with my code, it seems fine to me.
I set the header with char encoding
I saved the file in UTF-8 (No BOM)
This happens only, if you try to access to the page via $_GET on the internet-Explorer myscript.php?c=äüöß
When I write down specialchars on my site, they would displayed correct.
This is my Code:
// User Input
$_GET['c'] = "äüöß"; // Access URL ?c=äüöß
//--------
header("Content-Type: text/html; charset=utf-8");
mb_internal_encoding('UTF-8');
$_GET = userToUtf8($_GET);
function userToUtf8($string) {
if(is_array($string)) {
$tmp = array();
foreach($string as $key => $value) {
$tmp[$key] = userToUtf8($value);
}
return $tmp;
}
return userDataUtf8($string);
}
function userDataUtf8($string) {
print("1: " . mb_detect_encoding($string) . "<br>"); // Shows: 1: UTF-8
$string = mb_convert_encoding($string, 'UTF-8', mb_detect_encoding($string)); // Convert non UTF-8 String to UTF-8
print("2: " . mb_detect_encoding($string) . "<br>"); // Shows: 2: ASCII
$string = preg_replace('/[\xF0-\xF7].../s', '', $string);
print("3: " . mb_detect_encoding($string) . "<br>"); // Shows: 3: ASCII
return $string;
}
echo $_GET['c']; // Shows nothing
echo mb_detect_encoding($_GET['c']); // ASCII
echo "äöü+#"; // Shows "äöü+#"
The most confusing Part is, that it shows me, that's converted from UTF-8 to ASCII... Can someone tell me why it doesn't show me the specialchars correctly, whats wrong here? Or is this a Bug on the Internet-Explorer?
Edit:
If I disable converting it says, it's all UTF-8 but the Characters won't show to me either... They are displayed like "????"....
Note: This happens ONLY in the Internet-Explorer!
Although I prefer using urlencoded strings in address bar but for your case you can try to encode $_GET['c'] to utf8. Eg.
$_GET['c'] = utf8_encode($_GET['c']);
An approach to display the characters using IE 11.0.18 which worked:
Retrieve the Unicode of your character : example for 'ü' = 'U+00FC'
According to this post, convert it to utf8 entity
Decode it using utf8_decode before dumping
The line of code illustrating the example with the 'ü' character is :
var_dump(utf8_decode(html_entity_decode(preg_replace("/U\+([0-9A-F]{4})/", "&#x\\1;", 'U+00FC'), ENT_NOQUOTES, 'UTF-8')));
To summarize: For displaying purposes, go from Unicode to UTF8 then decode it before displaying it.

I have a Unicode text-block, like this:
ụ
ư
ứ
Ỳ
Ỷ
Ỵ
Đ
Now, I want to convert this orginal Unicode text-block into a text-block of UTF-8 (HEX) code point (see the Hexadecimal UTF-8 column, on this page: https://en.wikipedia.org/wiki/UTF-8), by PHP; like this:
\xe1\xbb\xa5
\xc6\xb0
\xe1\xbb\xa9
\xe1\xbb\xb2
\xe1\xbb\xb6
\xe1\xbb\xb4
\xc4\x90
Not like this:
0x1EE5
0x01B0
0x1EE9
0x1EF2
0x1EF6
0x1EF4
0x0110
Is there any way to do it, by PHP?
I have read this topic (PHP: Convert unicode codepoint to UTF-8). But, it is not similar to my question.
I am sorry, I don't know much about Unicode.
I think you're looking for the bin2hex() function:
Convert binary data into hexadecimal representation
And format by prepending \x to each byte (00-FF)
function str_hex_format ($bin) {
return '\x'.implode('\x', str_split(bin2hex($bin), 2));
}
For your sample:
// utf8 encoded input
$arr = ["ụ","ư","ứ","Ỳ","Ỷ","Ỵ","Đ"];
foreach($arr AS $v)
echo $v . " => " . str_hex_format($v) . "\n";
See test at eval.in (link expires)
ụ => \xe1\xbb\xa5
ư => \xc6\xb0
ứ => \xe1\xbb\xa9
Ỳ => \xe1\xbb\xb2
Ỷ => \xe1\xbb\xb6
Ỵ => \xe1\xbb\xb4
Đ => \xc4\x90
Decode example: $str = str_hex_format("ụưứỲỶỴĐ"); echo $str;
\xe1\xbb\xa5\xc6\xb0\xe1\xbb\xa9\xe1\xbb\xb2\xe1\xbb\xb6\xe1\xbb\xb4\xc4\x90
echo hex2bin(str_replace('\x', "", $str));
ụưứỲỶỴĐ
For more info about escape sequence \x in double quoted strings see php manual.
PHP treats strings as arrays of characters, regardless of encoding. If you don't need to delimit the UTF8 characters, then something like this works:
$str='ụưứỲỶỴĐ';
foreach(str_split($str) as $char)
echo '\x'.str_pad(dechex(ord($char)),'0',2,STR_PAD_LEFT);
Output:
\xe1\xbb\xa5\xc6\xb0\xe1\xbb\xa9\xe1\xbb\xb2\xe1\xbb\xb6\xe1\xbb\xb4\xc4\x90
If you need to delimit the UTF8 characters (i.e. with a newline), then you'll need something like this:
$str='ụưứỲỶỴĐ';
foreach(array_slice(preg_split('~~u',$str),1,-1) as $UTF8char){ // split before/after every UTF8 character and remove first/last empty string
foreach(str_split($UTF8char) as $char)
echo '\x'.str_pad(dechex(ord($char)),'0',2,STR_PAD_LEFT);
echo "\n"; // delimiter
}
Output:
\xe1\xbb\xa5
\xc6\xb0
\xe1\xbb\xa9
\xe1\xbb\xb2
\xe1\xbb\xb6
\xe1\xbb\xb4
\xc4\x90
This splits the string into UTF8 characters using preg_split and the u flag. Since preg_split returns the empty string before the first character and the empty string after the last character, we need to array_slice the first and last characters. This can be easily modified to return an array, for example.
Edit:
A more "correct" way to do this is this:
echo trim(json_encode(utf8_encode('ụưứỲỶỴĐ')),'"');
The main thing you need to do is to tell PHP to interpret the incoming Unicode characters correctly. Once you do that, you can then convert them to UTF-8 and then to hex as needed.
This code frag takes your example character in Unicode, converts them to UTF-8, and then dumps the hex representation of those characters.
<?php
// Hex equivalent of "ụưứỲỶỴĐ" in Unicode
$unistr = "\x1E\xE5\x01\xB0\x1E\xE9\x1E\xF2\x1E\xF6\x1E\xF4\x01\x10";
echo " length=" . mb_strlen($unistr, 'UCS-2BE') . "\n";
// Here's the key statement, convert from Unicode 16-bit to UTF-8
$utf8str = mb_convert_encoding($unistr, "UTF-8", 'UCS-2BE');
echo $utf8str . "\n";
for($i=0; $i < mb_strlen($utf8str, 'UTF-8'); $i++) {
$c = mb_substr($utf8str, $i, 1, 'UTF-8');
$hex = bin2hex($c);
echo $c . "\t" . $hex . "\t" . preg_replace("/([0-9a-f]{2})/", '\\\\x\\1', $hex) . "\n";
}
?>
Produces
length=7
ụưứỲỶỴĐ
ụ e1bba5 \xe1\xbb\xa5
ư c6b0 \xc6\xb0
ứ e1bba9 \xe1\xbb\xa9

I've always had problems with iconv. Now I must convert string to Windows-1250 and this doesn't seems to work:
$string = "ľaľa ho papľuha, ogrcal mi krpce!";
echo $string . ' ( ' . mb_detect_encoding($string) . ' ) <br>';
$string_encoded = iconv( mb_detect_encoding( $string ), 'Windows-1250//TRANSLIT', $string );
echo $string_encoded . ' ( ' . mb_detect_encoding($string_encoded) . ' ) <br>';
$string_encoded = mb_convert_encoding( $string, 'Windows-1250' );
echo $string_encoded . ' ( ' . mb_detect_encoding($string_encoded) . ' ) <br>';
The three echos above output exactly this:
ľaľa ho papľuha, ogrcal mi krpce! ( UTF-8 )
�a�a ho pap�uha, ogrcal mi krpce! ( )
mb_convert_encoding() Unknown encoding "Windows-1250" ( ASCII )
Since I've always seen this diamond question marks I wonder if this PHP function works at all. How can I convert UTF-8 to Windows-1250?
The file was saved in notepad+ in UTF-8
Also I've tried header('Content-Type: text/html; charset=windows-1250'); and setLocale()
I have experienced a similar issue. While reading CSV file, word "Česká republika" was read as "Èeská republika".
This solved it for me:
iconv( "Windows-1250", "UTF-8", ($string));
The � character is an indication that your text is being interpreted as UTF-8, but at this point an invalid byte sequence was encountered. Meaning, you're not serving UTF-8, yet the client is reading it as UTF-8. Which would imply that iconv is working just fine and whoever is reading the result just didn't get the message that it should be interpreting it as Windows-1250.
See What Every Programmer Absolutely, Positively Needs To Know About Encodings And Character Sets To Work With Text and Handling Unicode Front To Back In A Web App.
Is old post but you can convert UTF-8 to Windows-1252 and you will have same effect:
$str = "ľaľa ho papľuha, ogrcal mi krpce!"
$str = mb_convert_encoding( $str, "Windows-1252", "UTF-8" );
but if you realy need Windows-1250 you can use THIS SOLUTION and adapt to your need.
Correct answer is iconv( "UTF-8", "Windows-1250", $string );
I'm trying to check if a string is start with '€' or '£' in PHP.
Below are the codes
$text = "€123";
if($text[0] == "€"){
echo "true";
}
else{
echo "false";
}
//output false
If only check a single char, it works fine
$symbol = "€";
if($symbol == "€"){
echo "true";
}
else{
echo "false";
}
// output true
I have also tried to print the string on browser.
$text = "€123";
echo $text; //display euro symbol correctly
echo $text[0] //get a question mark
I have tried to use substr(), but the same problem occurred.
Characters, such as '€' or '£' are multi-byte characters. There is an excellent article that you can read here. According to the PHP docs, PHP strings are byte arrays. As a result, accessing or modifying a string using array brackets is not multi-byte safe, and should only be done with strings that are in a single-byte encoding such as ISO-8859-1.
Also make sure your file is encoded with UTF-8: you can use a text editor such as NotePad++ to convert it.
If I reduce the PHP to this, it works, the key being to use mb_substr:
<?php
header ('Content-type: text/html; charset=utf-8');
$text = "€123";
echo mb_substr($text,0,1,'UTF-8');
?>
Finally, it would be a good idea to add the UTF-8 meta-tag in your head tag:
<meta charset="utf-8">
I suggest this as the easiest solution to you. Convert the symbols to their unicode identifiers using htmlentities().
htmlentities($text, ENT_QUOTES, "UTF-8");
Which will either give you £ or €. Now that allows you to run a switch() {case:} statement to check. (Or your if statements)
$symbols = explode(";", $text);
switch($symbols[0]) {
case "£":
echo "It's Pounds";
break;
case "&euro":
echo "It's Euros";
break;
}
Working Example
This happens because you’re using a multi-byte character encoding (probably UTF-8) in which both € and £ are recorded using multiple bytes. That means that "€" is a string of three bytes, not just one.
When you use $text[0] you're getting only the first byte of the first character, and so it doesn't match the three bytes of "€". You need to get the first three bytes instead, to check whether one string starts with another.
Here’s the function I use to do that:
function string_starts_with($string, $prefix) {
return substr($string, 0, strlen($prefix)) == $prefix;
}
The question mark appears because the first byte of "€" isn’t enough to encode a whole character: the error is indicated by ‘�’ when available, otherwise ‘?’.
