PHP Validation Chinese Express!!!!!!!

PHP U9

How to use PHP to verify Chinese letters and numbers,

[\U4E00-\U9FA5] This can be verified in Chinese????? Tokyu

Reply to discussion (solution)

[\x4e00-\x9fa5]

It should be [\X4E00-\X9FCF]
Now the software basically supports the Unicode 6.1 version, can not use the old three

No, [\u4e00-\u9fa5] is the JS regular use

Now that you think of it, you're using a utf-8 code.
PHP regular writing [\x{4e00}-\x{9fa5}] plus u modifier
But now that you have the U modifier, \w already contains Chinese.

if (Ereg (' ^[\x4e00-\x9fcf]{1,100}$ ', ' haha haha only ')) {
echo "Pass";
}else{
echo "Error";
}
?>
Or is it wrong?

gb2312 not understand JS also use is gb2312

The browser unifies all incoming data into Unicode encoding, which is ucs-2 for the Simplified Chinese environment.
And \u4e00-\u9fa5 is the Ucs-2 encoding range of Chinese characters.

Yes, I understand.

But you said I couldn't use it in Eregi.

if (eregi ()) {
Ecjp ' right ';
}

Thank you!!!

Echo ' right ';

Is Ereg supported????

The Ereg series uses the POSIX regular
The Preg series uses the PCRE regular
They are not compatible!

and the Ereg function group will be abolished in the near future, it is recommended not to use
