PHP：如何使用分隔符拆分字符串

Question

I have this string that I would like to split.I want it to split the string starting with 1060 and retain the string but when I use preg_split(), it removes the string.

my code is this:

$array = preg_split("/1060[\s]*/",$str);

if there is any other method or function i can use, i will be very grateful.

Regards,

Positive lookaheads:

$array = preg_split("/(?=1060\s)/",$str);

(?=1060\s) is a positive lookahead - it asserts that the regex inside it (1060\s) can be matched, but doesn't match it. Therefore, this will match an empty string right before the match and split the text correctly.
