php数据传输

把下面代码保存为count.php

<?php
InitGP(array('action'));
if($action == 'count'){
InitGP(array('a','b','c','d','e','f','g','h','i','j'));
$jiafa = $a+$b+$c+$d+$e+$f+$g+$h+$i+$j;
$jianfa = $a-$b-$c-$d-$e-$f-$g-$h-$i-$j;
$chengfa = $a*$b*$c*$d*$e*$f*$g*$h*$i*$j;
$chufa = $a/$b/$c/$d/$e/$f/$g/$h/$i/$j;

echo "相加为{$jiafa}<br>";
echo "相减为{$jianfa}<br>";
echo "相乘为{$chengfa}<br>";
echo "相除为{$chufa}<br>";
}
function InitGP($keys,$method='GP',$htmcv=0){
!is_array($keys) && $keys = array($keys);
foreach($keys as $val){
$GLOBALS[$val] = NULL;
if($method!='P' && isset($_GET[$val])){
$GLOBALS[$val] = $_GET[$val];
} elseif($method!='G' && isset($_POST[$val])){
$GLOBALS[$val] = $_POST[$val];
