PHP Chinese and English mixed string interception_PHP tutorial

The article introduces a practical function. If we use php substr to intercept characters, it will be very problematic in Chinese. Today I wrote a better function for intercepting Chinese and English characters. Friends in need can refer to it. .

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

The code is as follows

代码如下	复制代码
function smssubstr($string, $length) {  if(strlen($string) <= $length) { return $string; } $strcut = ''; for($i = 0; $i < $length; $i++) { $strcut .= ord($string[$i]) > 127 ? $string[$i].$string[++$i] : $string[$i];  }  return $strcut; } for($i=1; $i<=$smsnum; $i++){ ${'smscontent'.$i} = smssubstr($message,$smsper); $message = str_replace(${'smscontent'.$i},"",$message); }

Copy code

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

Okay, friends in need can take it. I won’t go into details about the principle, just use it. http://www.bkjia.com/PHPjc/631690.htmlwww.bkjia.com
