$str = 'All are Chinese character tests';

} else {
echo 'Not all Chinese characters';
}
?>
When $str = 'All are Chinese characters test'; output "All are Chinese characters";
When $str = 'all are Chinese characters test'; output "not all Chinese characters";
| 代码如下 |
复制代码 |
$str = "php编程";
if (preg_match("/^[x{4e00}-x{9fa5}]+$/u",$str)) {
print("该字符串全部是中文");
} else {
print("该字符串不全部是中文");

$str = 'Chinese character 3 test';
If (preg_match("/([x81-xfe][x40-xfe])/", $str, $match)) {

} else {
echo 'Does not contain Chinese characters';
}
?>
When $str = 'Chinese character 3 test'; output "contains Chinese characters";
When $str = 'abc345'; output "does not contain Chinese characters";
The content of the above variable $str has nothing to do with utf8 or gbk encoding, the judgment result is the same.
