Implementation code to determine whether a string is all Chinese or contains Chinese in PHP_PHP Tutorial

1. The judgment is all in Chinese

Copy the code The code is as follows:

$str="'324 is";
if(!eregi("[^x80-xff]","$str")){
echo "All in Chinese";
}else{
echo "Not";
}

Second, determine whether it contains Chinese

Copy the code The code is as follows:

$str = "Chinese ";
if (preg_match("/[x7f-xff]/", $str)) {
echo "Contains Chinese";
}else{
echo "No Chinese";
}
or
$pattern = '/[^x00-x80]/';
if(preg_match($pattern,$str)){
echo "Contains Chinese";
}else{
echo "No Chinese";
}

I tested these methods under utf-8 and have not tested them under other encodings.
