PHP Learning Note string encoding conversion and judgment _php Tutorial

Copy CodeThe code is as follows:
Iconv (' GBK ', ' utf-8//ignore ', ' home of the script '); Converts a string from GBK encoding to UTF-8 encoding

However, Iconv can only solve the pre-known encoding situation, if the string encoding is unknown, you need to first probe its encoding, you may use the Mb_string extension library:

Copy the Code code as follows:
Mb_detect_encoding (' Home of the script ');

But mb_detect_encoding there is a mishap, often appear to judge inaccurate situation. Perhaps this will solve:

Copy the Code code as follows:
Use Iconv to convert and determine whether the equivalence is not high efficiency
function Is_utf8 ($STR) {
if ($str = = = Iconv (' UTF-8 ', ' Utf-8//ignore ', $str)) {
Return ' UTF-8 ';
}
}
Multiple coding scenarios
function detect_encoding ($STR) {
foreach (Array (' GBK ', ' UTF-8 ') as $v) {
if ($str = = = Iconv ($v, $v. '//ignore ', $str)) {
return $v;
}
}
}

After getting the string encoding information in the above way, you can use Iconv or mb_convert_encoding to convert the encoding.
