This article introduces a function used to intercept Chinese characters in php. Friends in need can refer to it.

Share a PHP Chinese character interception function that I have been using. It is very good. Friends who use it can take it.

Code:

<?php
/**
* @ 中文字符截取
* @ site：bbs.it-home.org
*/
function str_cut($string, $length, $dot = ”) {
if(strlen($string) <= $length) {
   return $string;
}
$strcut = ”;
for($i = 0; $i < $length - strlen($dot) - 1; $i++) {
 $strcut .= ord($string[$i]) > 127 ? $string[$i].$string[++$i] : $string[$i];
}
return $strcut.$dot;
}
?>
