Sharing of PHP interception string functions that support Chinese and other encodings (interception of Chinese strings)_PHP tutorial

Simple string interception method, supports Chinese and other encodings, just pass in the corresponding parameters and call it directly

Copy code The code is as follows:

/**
* String interception, supports Chinese and other encodings
* @static
* @access public
* @param string $str The string that needs to be converted
* @param string $start Start Position
* @param string $length truncate length
* @param string $charset encoding format
* @param string $suffix truncate display character
* @return string
*/
function msubstr($str, $ start=0, $length, $charset="utf-8", $suffix=true) {
if(function_exists("mb_substr"))
$slice = mb_substr($str, $start, $length , $charset);
elseif(function_exists('iconv_substr')) {
$slice = iconv_substr($str,$start,$length,$charset);
if(false === $slice ) {
              $slice = ''; xbf]|[xe0-xef][x80-xbf]{2}|[xf0-xff][x80-xbf]{3}/";
             $re['gb2312'] = "/[x01-x7f ]|[xb0-xf7][xa0-xfe]/";
$re['gbk'] = "/[x01-x7f]|[x81-xfe][x40-xfe]/";
$re['big5'] = "/[x01-x7f]|[x81-xfe]([x40-x7e]|xa1-xfe])/";
preg_match_all($re[$charset], $str , $match);
$slice = join("",array_slice($match[0], $start, $length));
}
return $suffix ? $slice.'... ' : $slice;
}
