Answer 1

What is the best way to separate string in two by given position?

If i understand you correctly, you can do:

$str = 'hello world';
$pos = 5;

$separated_str = substr($str, $pos);
echo $separated_str;

Result:

world

This depends on the structure of your string as there are other ways also to split the string.

Answer 2

You can use substr to get the two sub-strings:

$str1 = substr($str, 0, $pos);
$str2 = substr($str, $pos);

If you omit the third parameter length, substr takes the rest of the string.

But to get your result you actually need to add one to $pos:

$string = 'Some string';
$pos = 5;
$begin = substr($str, 0, $pos+1);
$end = substr($str, $pos+1);

Answer 3

How about substr()?

$string = 'Some string';
$pos = 5;

$beginning = substr($string, 0, $pos);
$end = substr($string, $pos);

Answer 4

Regex solution (if you are into it):

...
$string = 'Some string xxx xxx';
$pos = 5;

list($beg, $end) = preg_split('/(?<=.{'.$pos.'})/', $string, 2);

echo "$beg - $end";
