文章介绍一个实用的函数,我们如果用php substr来截取字符在中文上处理的很有问题,今天自己写了一个比较好的中文与英文字符截取的函数,有需要的朋友可以参考下。

 代码如下 复制代码

function smssubstr($string, $length) {
 if(strlen($string)   return $string; 
 }
 $strcut = '';
 for($i = 0; $i   $strcut .= ord($string[$i]) > 127 ? $string[$i].$string[++$i] : $string[$i];
 }
 return $strcut;
}

for($i=1; $i  ${'smscontent'.$i} = smssubstr($message,$smsper);
 $message = str_replace(${'smscontent'.$i},"",$message);
}

好了,有需要的朋友拿去吧,原理我也不说多了,可以用就行了。
