提问by Lotuspandiyan
I would like to get and display all variable names which are posted by method="post"in a form. I am not aware of variables which passed from post method in HTML. Is there any method to list the all variables posted by post method ?.. Thanks in advance.
我想获取并显示method="post"在表单中发布的所有变量名称。我不知道从 HTML 中的 post 方法传递的变量。有没有任何方法可以列出 post 方法发布的所有变量？ .. 提前致谢。
example: http://www.dhamu.in/oncreate2.php?workload=10&request_type=project&name=web%20design&description=we%20have%20done%20it&budget=1&bidperiod=11&project_guidelines=checked&job_113=1&xxxx=10Here i do no the variable name "xxxx"
例如：http: //www.dhamu.in/oncreate2.php?workload=10&request_type=project&name =web%20design & description=we%20have% 20done%20it&budget =1&bidperiod=11&project_guidelines =checked&job_113 =1&xxxx =10这里我不做变量名“xxx”

foreach ($_POST as $key => $value){
echo "{$key} = {$value}\r\n";
}
And BTW, those are $_GETvariables (so adjust the above to use foreach ($_GET as $key => $value){.) You can also use $_REQUESTto cover both.
顺便说一句，这些是$_GET变量（因此请调整上述内容以使用foreach ($_GET as $key => $value){。）您也可以使用$_REQUEST来涵盖两者。

Try:
尝试：
print_r(array_keys($_POST))
print_r(array_keys($_POST))
... for just the keys.
... 只为钥匙。
Or:
或者：
print_r($_POST)
print_r($_POST)
... for all the POST keys and values.
...对于所有 POST 键和值。

To output all POST variables, try this:
要输出所有 POST 变量，请尝试以下操作：
var_dump($_POST);
Variables which are included within the URL are GET variables actually:
URL 中包含的变量实际上是 GET 变量：
var_dump($_GET);
