中文验证函数(php javascript)
中文字符判断是根据字符串编码来的,/^[chr(0xa1)-chr(0xff)]+$这就是判断是否为中文的php验证正则表达式 下面来看一个验证中文实例
中文字符判断是根据字符串编码来的,/^[chr(0xa1)-chr(0xff)]+$这就是判断是否为中文的php教程验证正则表达式
下面来看一个验证中文实例
$str = "一聚教程网";
if (preg_match("/^[".chr(0xa1)."-".chr(0xff)."]+$/", $str)) {
echo "这是一个纯中文字符串";
} else {
echo "这不是一个纯中文字串";
}
js
var str = "php编程";
if (/^[u4e00-u9fa5]+$/.test(str)) {
alert("该字符串全部是中文");
} else {
alert("该字符串不全部是中文");
}php
if($en_utf8)
{ $joid = preg_replace("[^0-9a-za-z_-|x4e00-x9fa5|:|/|#|.]","",$joid); } //utf-8的中文匹配
else
{ $joid = preg_replace("[^0-9a-za-z_-|".chr(0xa1)."-".chr(0xff)."|:|/|#|.]","",$joid); } //gb2312的中文匹配
php中来判断字符串是否为中文,就会沿袭这个思路:
$str = "php编程";
if (preg_match("/^[u4e00-u9fa5]+$/",$str)) {
print("该字符串全部是中文");
} else {
print("该字符串不全部是中文");
}
?>
