`I have a problem with my restaurant website. When customers type in æ,ø,å as a comment to their order, then the printer cant print those characters because it doesnt support them.

So my question is, how can I make the system print "ae" instead of "æ", "o" instead of "ø" and "aa" instead of "å". I have uploadet a picture of the printer module coding. Thanks!

enter image description here

CodePudding user response：

Int the future please do not post images of code, copy/paste the code as text.

What you want is Transliteration:

$input = 'how can I make the system print "ae" instead of "æ", "o" instead of "ø" and "aa" instead of "å"';

$t = Transliterator::create("Any-Latin; Latin-ASCII");

var_dump($t->transliterate($input));

Output:

string(96) "how can I make the system print "ae" instead of "ae", "o" instead of "o" and "aa" instead of "a""

I know it doesn't transliterate 'å' as desired, but I would side with ICU's transliteration interpretation rather than trying to build a custom transliterator.

You might also want to check what encodings that your printer accepts, as it may well print an ISO-8859-1 or cp1252 version of the data just fine. Then you just have to apply the correct conversion, eg:

$newstring = mb_convert_encoding($input, "ISO-8859-1", "UTF-8");

CodePudding user response：

use str_replace in PHP

$text = str_replace(array('æ', 'ø', 'å'), array('ae', 'o', 'aa'), $text);

For more help, we need a few codelines before an d after.
