How does PHP accumulate numbers through recursive functions? This article mainly introduces the method of PHP using recursive functions to implement number accumulation, involving the skills of PHP recursive operations. I hope to be helpful.

The example in this article describes how PHP uses recursive functions to implement number accumulation. Share it with everyone for your reference. The specific implementation method is as follows:

<?php
function summation ($count) {
   if ($count != 0) :
     return $count + summation($count-1);
   endif;
}
$sum = summation(10);
print "Summation = $sum";
?>
