Rewrite the snippet below in PHP so it works the same as the original Python code.
from itertools import zip_longest def beadsort(l): return list(map(sum, zip_longest(*[[1] * e for e in l], fillvalue=0))) print(beadsort([5,3,1,7,4,1,1]))
<?php function columns($arr) { if (count($arr) == 0) return array(); else if (count($arr) == 1) return array_chunk($arr[0], 1); array_unshift($arr, NULL); $transpose = call_user_func_array('array_map', $arr); return array_map('array_filter', $transpose); } function beadsort($arr) { foreach ($arr as $e) $poles []= array_fill(0, $e, 1); return array_map('count', columns(columns($poles))); } print_r(beadsort(array(5,3,1,7,4,1,1))); ?>
Convert this Python block to PHP, preserving its control flow and logic.
