MAX numeric value from mixed array

I have an array that contains both strings and numeric values, While using this code I keep getting the highest string value, how to get only numeric max values from the array?

$maxprice = max($textpieces);

I have also tried this but this just returns the number of keys in the array

 $maxprice = max(array_search($textpieces));

thanks for your help! I have looked but the max function here does not give any information http://php.net/manual/en/function.max.php

I have also looked at this solution Find highest max() of mixed array but is it possible to get it without building an custom function?

$maxprice = max(array_filter($textpieces, 'is_numeric'));

It at first filters only entries that contains digits only (integers) and then extracts max() from it

The following solution:

$max = array_reduce($textpieces, function($max, $i) {
    if (is_numeric($i) && $i > $max) {
        return $i;
    }

    return $max;
});

var_dump($max);

could be a bit more performance (from both CPU and memory perspectives) but is more complicated as well.
