php detect encoding

In order to check if a string is encoded correctly in utf-8, I suggest the following function, that implements the RFC3629 better than mb_check_encoding(): Detect Character Encoding used to encode text in Base64. $detect_order = array('ASCII', 'UTF-8', 'ISO-8859-1', 'Windows-1252');or encode to windows-1252 or iso-8859-15 (same thing than iso-8859-1 but has € symbol)Thanks for contributing an answer to Stack Overflow!

Véanse las codificaciones admitidas.. Si se omite encoding_list, devolverá el orden actual de detección de las codificaciones de caracteres como un array.. Este parámetro afecta a mb_detect_encoding() y a mb_send_mail(). Stack Overflow works best with JavaScript enabled

Unlike other comments suggest, there's no need to serialize a string to use preg_match's "u" modifier for testing if a string is valid UTF-8. Free 30 Day Trial

Parámetros. Currently it can distinguish UTF-8, UTF-16, UTF-32 little or big endian encodings. Yet like you said PHP website states the opposite.

If Check if strings are valid for the specified encoding your coworkers to find and share information. shouldn't my $detect_order = array('ASCII', 'ISO-8859-1', 'Windows-1252','UTF-8'); Active 6 years, 1 month ago. I'm building a html scrapers of mostly english sites that collects data and stores it into UTF-8 XML. Featured on Meta You can only check whether a string is valid in a given encoding. 1. first of all i'd like to say i've read the other post regarding php's mb_detect_encoding at Strange behaviour of mb_detect_order() in PHP. ut8_encode converts only ISO-8859-1 to UTF-8. php's mb_detect_encoding() Ask Question Asked 8 years, 8 months ago.

Note that the algorithm in javalc6's comment checks UTF-8 compliance by the letter of the specs.

what is the proper detect order if not "ISO-88591, UTF-8" ? By using our site, you acknowledge that you have read and understand our

Stack Overflow for Teams is a private, secure spot for you and encoding_list. Is it possible to detect strings in such a way that gives me the lowest ranking set ? It returns false for unknown encodings. if you need to convert between different encodings, you should use other functions.With respect to Euro mark. encoding_list es un array o una lista de codificaciones de caracteres separadas por comas. The order is important because windows-1252 and ISO-8859 will match almost any byte string except possibly in the control-character range. This function does not check for bad byte sequence(s), it only checks if the byte stream is valid. How to distinguish between ISO-8859-1 vs. UTF-8 ?

Questions: I have a script which combines a number of files into one, and it breaks when one of the files has UTF8 encoding.

If you take one or the other out, you'll get whatever is left from the two. if first character in string is not windows-1252, even though the rest of it is, it fails ?

If you want to verify a encoded string is valid, (IE: does not contain any bad byte sequences do the following.../* test 1 mb_check_encoding (test for bad byte stream) *//* test 1 checkEncoding (test for bad byte sequence(s)) *//* test 2 mb_check_encoding (test for bad byte stream) *//* test 2 checkEncoding (test for bad byte sequence(s)) */ Posted by: admin December 15, 2017 Leave a comment.

As I understand it, windows-1252 is a superset of iso-8859-1, which prompts me to think why bother using utf8_encode() at all ? It seems that the function detects valid and invalid byte sequences correctly according to UTF-8 and the Unicode specifications, except for one issue: Go to iconv() or mb_convert_encoding. Hello!

(ie. specifically the right single quote (’) 0x92. You can just use So the positioning of the last 2 below doesn't seem to make a difference$detect_order = array('ASCII', 'UTF-8', 'Windows-1252', 'ISO-8859-1'); This class can detect the encoding of text from a file or string. I know this is incorrect as it gave me the following resultswhy is my detect order of ('ASCII', 'ISO-8859-1', 'Windows-1252','UTF-8') wrong for what I want to get ?both of the following mb_detect_order array gave me the above valuesphew, can someone shed some light on this ? thanks alot appreciated it !Not sure if I will answer all of your questions, but here we go:As I understand it, windows-1252 is a superset of iso-8859-1, which prompts me to think why bother using utf8_encode() at all ? Not sure if this got added (officially or unofficially) to the ISO-8859-1 at some point but both of the statement below return trueNotice, it's the result with strict set to True or False. I noticed you switched UTF-8, ahead of ISO in the latter order an that's why it gave you UTF-8 at the end.why is my detect order of ('ASCII', 'ISO-8859-1', 'Windows-1252','UTF-8') wrong for what I want to get ?From what I've seen, it seems that if you have both ISO-8859-1 and Windows-1252 in there, you'll get ISO back.
