PHP converts the encoding of all files in the folder_PHP tutorial

The encoding of all files in the PHP conversion folder is suitable for publishing other encoding versions of the website. For example, if you have a GBK version and you want to have a UTF8 version, or you only have the source code of GBK and you want secondary development but you don’t want to change the encoding method of the IDE You can use this program to batch convert it to UTF8:

The code is as follows:

@param string $filename
*/function iconv_file($filename,
$input_encoding='gbk',
$output_encoding='utf-8'){ if(file_exists($filename))
{ if(is_dir($filename)) {
foreach (glob("$filename/*") as $key=>$value) {
iconv_file($value); } } else {
$contents_before = file_get_contents($filename);
/*$encoding = mb_detect_encoding($contents_before,
array('CP936','ASCII','GBK','GB2312','UTF-8'));
echo $encoding;
if($encoding=='UTF-8') mb_detect_encoding function not working
{        return;                                                                                                                                $contents_after = iconv($input_encoding,$output_encoding,$contents_before);
file_put_contents($filename, $contents_after); } } else
{ echo 'Parameter error'; return false; }}iconv_file('./test');?>
