mb_internal_encoding — Set/Get internal character encoding
Set/Get the internal character encoding
encoding
encoding is the character encoding name
used for the HTTP input character encoding conversion, HTTP output
character encoding conversion, and the default character encoding
for string functions defined by the mbstring module.
You should notice that the internal encoding is totally different from the one for multibyte regex.
If encoding is set, then
Returns TRUE on success or FALSE on failure.
In this case, the character encoding for multibyte regex is NOT changed.
If encoding is omitted, then
the current character encoding name is returned.
Example #1 mb_internal_encoding() example
<?php
/* Set internal character encoding to UTF-8 */
mb_internal_encoding("UTF-8");
/* Display current internal character encoding */
echo mb_internal_encoding();
?>
