On Steem Blockchain, the reputation can be formatted in a logarithmetic (base 10) scale. Given recently, my PR to fix the reputation formatter in SteemJS is merged, I also translate this to PHP which I need.

function formatReputation($rep) {
    if (!$rep) return 25;
    $neg = $rep < 0;
    $rep = (string)$rep;
    $rep = $neg ? substr($rep, 1) : $rep;
    $v = log10(($rep > 0 ? $rep : -$rep) - 10) - 9;
    $v = $neg ? -$v : $v;
    return round($v * 9 + 25, 3);
}
function formatReputation($rep) {
    if (!$rep) return 25;
    $neg = $rep < 0;
    $rep = (string)$rep;
    $rep = $neg ? substr($rep, 1) : $rep;
    $v = log10(($rep > 0 ? $rep : -$rep) - 10) - 9;
    $v = $neg ? -$v : $v;
    return round($v * 9 + 25, 3);
}

Some Example usages:

echo formatReputation(95832978796820) . "\n";
echo formatReputation(10004392664120) . "\n";
echo formatReputation(30999525306309) . "\n";
echo formatReputation(-37765258368568) . "\n";
echo formatReputation(334486135407077) . "\n";
echo formatReputation(0) . "\n";
echo formatReputation(95832978796820) . "\n";
echo formatReputation(10004392664120) . "\n";
echo formatReputation(30999525306309) . "\n";
echo formatReputation(-37765258368568) . "\n";
echo formatReputation(334486135407077) . "\n";
echo formatReputation(0) . "\n";

The above PHP code should output the following values (you can use them to unit test the function):

69.834
61.002
65.422
-16.194
74.719
25
