[SOLVED] split variable for only the last 4 digits

[DrTrans]

my variable : $variable = "27-5274594" 

 

How do i pull the last 4 digits of the $variable  without setting $variable = "4594";

 

in example:

 

$variable = $row['TaxID'];

<< Where variable would be transformed to only the last 4 digits >>

 

print "$variable";

substr

$variable=substr($row['TaxID'],-4); 

 

to get the first part

$variable=substr($row['TaxID'],0,-4);
