will do fine.

But not the same. Their versions grab everything after the last =, your version grabs evertyhing after the first one.
I think your solution is better (and I'm sure it's a lot more efficient), but we can't know for sure without more information.

$\ = "\n";

for ('title=foo' ,'title=foo=bar') {
    print "-> $_";
    print /.*=(.*)/;
    print /=(.*)/;
}

Eh, no. Only *one* of their versions grabs everything after the last, the other grabs everything after the first. The problem however didn't specify what should happen if there are multiple = characters present.
