问题:

I am trying to recreate a string but I am having issues with the utf-8 encoding (I guess?)

I am using the code below to format a string

$pre_subject = (strip_tags(html_entity_decode($temp_subject)));
$pre_subject = str_replace('Â', '', $pre_subject);
$pre_subject = iconv('UTF-8', 'ASCII//TRANSLIT//IGNORE', $pre_subject);

The problem is that instead of getting the result as in the 1st sentence below, I get a result as the second one.

1st. summary: SHANGHAI room - Réunion 
2nd. summary: SHANGHAI room - R'eunion

I need to keep the format as the first example, how can I modify my code for that?

回答1:

The string has UTF-8 characters. You need to either decode them, or tell whatever is reading it to use UTF-8 encoding.

So, this:

$pre_subject = (strip_tags(html_entity_decode($temp_subject)));
$pre_subject = str_replace('Â', '', $pre_subject); // if this was trying to fix the problem, remove it
$pre_subject = utf8_decode($pre_subject);

Or add this to <head>:

<meta charset="utf-8">

Make you PHP header like:

header('Content-Type: text/html; charset=utf-8');

also, when dealing with utf-8, if you need to do string replace use mb_str_replace and not str_replace

UTF-8 encoding issue in php, special characters
