php - issus with emoji in array -

In this code, when I use ":-)" emoji, I do not see it in the output.

But when "1f60a" or "1f60c" or "e252" emoji is used, what is the problem?

  & lt ;? Php $ emoji_url = "http://coremobile.ir/images_smileys"; $ Emoji_style = ""; $ Emoji_code = Array (":-)", "1f60a", "1f60c", "e252"); $ Emoji_img = array ('& lt; img src =' '. $ Emoji_url.' / 1f60a.png ''. $ Emoji_style. '& Gt;', '& lt; img src = "'. $ Emoji_url. '/ 1f60a.png "$ .imoji_style. '& Gt;', '& lt; img src ="'. $ Emoji_url. '/ 1f60c.png "' $ emoji_style. '& Gt;', '& lt; img src = "$ .imoji_url. '/ E252.png' '. $ Emoji_style.' & Gt; '); $ Ret =' This test :-) 1f60a '; $ Ret = str_replace ($ emoji_code, $ emoji_img, $ ret) ; Echo $ ret?; & Gt;  

This should work for you:

(just use instead, so that it does not go through the string multiple times)

  $ ret = strtr ($ ret, array_combine ($ emoji_code, $ emoji_img)) ;  

Output:

This test

No one else has done the work, because it takes the place of every match for the first replacement and then the second and so on.

  This test :-) 1f60a // ^ ^ match

  this test & lt; Img src = "http://coremobile.ir/images_smileys/1f60a.png" & gt; 1f60a // ^^^^^ Match ^ ^^^^ Match
