php - catch notification of explode() -

i process input of users.

input should have format:

text. address: xyz 

now tried use:

$address = explode('address: ', $text)[1]; 

but causes error in case of user input doesn't match needed format.

how prevent (maybe including check), script won't trigger notice?

first assign variable:

$address = explode("address: ", $text); 

then check if set key 1:

if (isset($address[1]) {     $address = $address[1]; } 

then shouldn't have notices because next time you'll existing parameter in array.
