How to add <br> before Chinese character if Chinese wording is combined with normal text.
<?php
$string = 'Hello World 自立合作社';
/*
this is what I tried:
preg_match('/\\p{Han}/u', $string, $matches);
print_r($matches)
*/
?>
Output:
Hello World</br>自立合作社
This is surely not the best solution, but one approach would be to match a string of ASCII characters via [\x00-\x7F]+ followed by a non-ASCII sequence (same pattern negated with ^). It does not target Chinese specifically, but that is tricky owing to the varied ranges of Chinese Unicode characters.
$string = 'Hello World 自立合作社';
// Capture ASCII sequence into $1 and non-ASCII into $2
echo preg_replace('/([\x00-\x7F]+)([^\x00-\x7F]+)/', '$1<br/>$2', $string);
// Prints:
// Hello World
// 自立合作社

Actually, here's an improved version that does specifically target Chinese characters via \p{Han}. The $2 capture also includes \s for whitespace.
// This matches any non-Chinese in $1 followed by Chinese (and whitespace) in $2
echo preg_replace('/([^\p{Han}]+)([\p{Han}\s]+)/', '$1<br/>$2', $string);
I am no Chinese but I hope this helps.
As you are using php you can use preg_replace with look ahead construct. It will replace all white space characters (those before chinese character) with a <br>.
$string = 'Hello World 自立合作社';
$pattern = "/\\p{Z}(?=\\p{Han})/ui"; // matches a white space before Chinese character.
$brStr = preg_replace($pattern, "<br>", $string);
echo $brStr;
I don't know will \p{Han} match all Chinese characters so checkout more info on unicode characters here
Hope this helps. Good luck! ;)
