执行java脚本并在我的php查询中使用结果

我有一个执行计算的java脚本函数。我想在我的 php 代码中使用该计算的答案。

document.write(Fixed((PoissonTerm( X, Y )),8,4))

值 X 和 Y 都来自我的 php 代码中的变量，所以

<?php
$valueofx;
$valueofy;
?>

在理想的世界中，我想看起来像这样

<?php
$thejavascriptvalue = document.write(Fixed((PoissonTerm( $valueofx, $valueofy )),8,4))
?>

我知道这不可能做到，我需要拉取和使用 5 个不同的值。无论如何我可以解决它吗？我不介意刷新页面或从另一个页面抓取它，只要我可以在我的 php 代码中使用 5 个值。

我需要运行 javascript 10 次才能重定向，例如

 document.write(Fixed((PoissonTerm(0.1, 0 )),8,4))
   document.write(Fixed((PoissonTerm( 8, 2 )),8,4))
   document.write(Fixed((PoissonTerm( 6, 3 )),8,4))

下面如果 JavaScript

function Fixed( s, wid, dec ) {
   // many combinations of possibilities
   // maybe prepare for upcoming truncate
   var z = 1
   if (dec > 0) {
      z /= Math.pow( 10, dec );
      if (s < -z)  s -= 0.5 * z;
      else
         if (s > z)  s += 0.5 * z;
         else
            s = 0;
      }
   // assure a string
   s = "" + s;
   // chop neg, if any
   var neg = 0;
   if (s.charAt(0) == "-") {
      neg = 2;
      s = s.substring( 1, s.length );
      }
   // chop exponent, if any
   var exp = "";
   var e = s.lastIndexOf( "E" );
   if (e < 0)  e = s.lastIndexOf( "e" );
   if (e > -1) {
      exp = s.substring( e, s.length );
      s = s.substring( 0, e );
      }
   // if dec > 0 assure "."; dp == index of "."
   var dp = s.indexOf( ".", 0 );
   if (dp == -1) {
      dp = s.length;
      if (dec > 0) {
         s += ".";
         dp = s.length - 1;
         }
      }
   // assure leading digit
   if (dp == 0) {
      s = '0' + s;
      dp = 1;
      }
   // not enough dec pl?  add 0's
   while ((dec > 0) && ((s.length - dp - 1) < dec))
      s += "0";
   // too many dec pl?  take a substring
   var places = s.length - dp - 1;
   if (places > dec)
      if (dec == 0)
         s = s.substring( 0, dp );
      else
         s = s.substring( 0, dp + dec + 1 );
   // recover exponent, if any
   s += exp;
   // recover neg, if any
   if (neg > 0)
      s = "-" + s;
   // if not enough width, add spaces IN FRONT
   //    too many places?  tough!
   while (s.length < wid)
      s = " " + s;
   return s
