Solution:2

Why you don’t use the substr function?

string substr ( string $string , int $start [, int $length ] )

for example the first 5 characters.

$ret = substr("yourstring", 5);

If you need something from behind you can use a negative value.

$ret = substr("yourstring", -5);

and if you need a range then you can use the length to define how many characters you need.

$ret = substr("yourstring", 5, 5);
