Question

php 用print_r($_GET)查看数组发现名称后面多了个下划线_

如：print_r($_GET);本应输出：array ( [ action ] => delete ) 结果输出的是：array ( [ action_ ] => delete )。实在是找不到原因，望大师指教.谢谢！
有关联的js内容为：
window.onload = function() {
var ret = document.getElementById('return');
var del = document.getElementById('delete');
ret.onclick = function() {
history.back();
};
del.onclick = function () {
if (confirm('您确定要调用吗？')){
location.href = '?action = delete';
}
};
};
有关联的php内容：
print_r($_GET);
<dd class="button"><input type="button" value="返回列表" id="return"/> <input type="button" id="delete" value="删除信息" /></dd>
