Get a particular string using preg_match_all

i want to find the string after "-" which is exactly in 3rd position, If it doesn't find the "-" it should get the whole string. sample data are

TT-people // get people
1V-NEWTET // get NEWTET
ZZ-YESforTHE // get YESforTHE
Computer // get Computer
T-Book // get T-Book

I tried as

$result=preg_match_all("/^[a-zA-Z0-9]2-(\s\w*)/",$data,$networkID);
echo $networkID[0][1]

please rectify my error.

if its a single line if text you can do:

if(substr($string, 2, 1) === "-"){
    echo substr($string, 3);
}else{
    echo $string;
}

[a-zA-Z0-9]2

The 2 here just matches the character “2”. Looks like you meant {2}.

To reflect your updated question, it should look like this:

$result = preg_match_all('/^(?:[a-zA-Z0-9]{2}-)?(\s\w*)/', $data, $networkID);
echo $networkID[0][1];

The ? makes the group optional.
