在php中使用正则表达式匹配或任何其他方式拆分unicode单词

Question

Need to search n split specific part from unicode string for example if word is لاحاصل need to search لا out of it in shape of matches as حاصل and لا any help ?

Answer 1

You could use preg_split with the u modifier to have multi-byte support. Then you can use the fourth argument to specify you want both the delimiter and delimited parts:

$word = "لاحاصل";
$entry = "لا";
$arr = preg_split("/($entry)/u", $word, null,
                  PREG_SPLIT_DELIM_CAPTURE + PREG_SPLIT_NO_EMPTY); 
echo $arr[0] . "<br>"; // لا
echo $arr[1] . "<br>"; // حاصل

Don't forget the brackets around $entry to make it a capture group. This way it works with PREG_SPLIT_DELIM_CAPTURE.
