本文实例讲述了php实现过滤字符串中的中文和数字。分享给大家供大家参考。具体实现方法如下:
function getChinese($string,$encode="GBK") {
switch($encode){
case "GBK" :$codelength=2;break;
case "GB2312" :$codelength=3;break;
case "UTF-8" :$codelength=3;break;
case "UTF-16" :$codelength=4;break;
}
$tmpstr = '';
$arr = array(1,2,3,4,5,6,7,8,9,0);
$strlen = strlen($string);
for($i=0; $i<$strlen; $i++) {
$str=substr($string, $i, 1);
$str1=trim($str);
if( ord($str)>0xA0 ){
$tmpstr.= substr($string, $i, $codelength);
$i = $i+$codelength-1;
}
}
return $tmpstr;
}
希望本文所述对大家的php程序设计有所帮助。
