PHP string interception function_PHP tutorial

This article introduces a function that comes with PHP to intercept strings. It can only handle English. Numbers cannot intercept mixed Chinese characters. Friends in need can refer to it. The latter one is easier to use. The first one is mainly for For beginners to learn from. ​

代码如下

复制代码

/* ------------------------------------------------------ 参数： $str_cut    需要截断的字符串 $length     允许字符串显示的最大长度 程序功能：截取全角和半角（汉字和英文）混合的字符串以避免乱码 ------------------------------------------------------ */ function substr_cut($str_cut,$length) {     if (strlen($str_cut) > $length)     {         for($i=0; $i < $length; $i++) if (ord($str_cut[$i]) > 128)    $i++;         $str_cut = substr($str_cut,0,$i)."..";     }     return $str_cut; } ?>

/*

function substr_cut($str_cut,$length)
