I need to separate numbers contains more than 3 symbols.

Answer 1

preg_replace alone without any callback function would be sufficient.
preg_replace('~#\d+(*SKIP)(*F)|(?<=\d)(?=\d)~', ' ', $str);
DEMO
#\d+(*SKIP)(*F) Matches and discards all the numbers which starts with #.
| OR
(?<=\d)(?=\d) Now from the remaining string, this would match the boundary which exists between two digits.
Now by replacing the matched boundary with space will give you the desired output.

Answer 2

You could use a callback for this:
$str = preg_replace_callback('~\b\d{4,}~',
function($m) {
return implode(' ', str_split($m[0]));
}, $str);
eval.in

Answer 3

Also can do this by using the \G anchor. Replace with matched digit + space: "$0 "
I need to separate numbers contains more than 3 symbols.
$str = preg_replace('~\b\d(?=\d{3})|\G\d\B~', "$0 ", $str);
\b\d matches a word-boundary \b followed by a digit (\d is a short for [0-9])
(?=\d{3}) Using a lookahead to check next 3 after first \d are digits too
|\G\d\B OR match a digit at \G end of previous match followed by \B non word-boundary
See test at regex101 or eval.in
As an alternative could also replace first digit after a \h horizontal space: \h\d|\G\d\B

Answer 4

Try this.
$phonenumber="7962555443";
$formatted = implode(' ',str_split($phonenumber));

Answer 5

You can use implode you just need to use str_split first which converts the string to an array:
$number="905488739038";
$formatted = implode(' ',str_split($number));
echo $formatted;
Output:
9 0 5 4 8 8 7 3 9 0 3 8

Answer 6

You may try this regex as well:
((?:(?:\d)\s?){4,})
It will capture all the number having length four or more. Also you need to do an additional step to remove spaces from the matches from the results like this:
7 9 6 2 5 5 5 4 4 3
