Question

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

...??...

$begging // == 'Some s';
$end // == 'tring';

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

Answer 1

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;
$begin = substr($string, 0, $pos+1);
$end = substr($string, $pos+1);
