How to tell if a post is posted, or just empty

Is it possible to tell whether the Post is just Empty, or Just hasn't been posted yet? I know

if($_POST['varible']!="") {
    $loginerr="";
} else  {
    $loginerr="Please check your entry.";
}

or

if(ifempty($_POST['varible']) {
    $loginerr="Please Check your Entry.";
} else {
    $loginerr="";
}

I just want a way, to tell whether the $_POST has been sent or not.

<?php
//save it in a variable
$variable = $_POST['variable'];
//now check
if(empty($variable )) {

echo "The field was empty";

}
else
{
//whatever you want
}
?>

PHP isset is used for checking the row exist in array. empty is used for checking the array value. So here we can use this two in if condition is better. 

 if(isset($_POST['vaiable']) && !empty($_POST['vaiable'])){

 //Here all the condition is satisfied and the $_POST['vaiable'] definitely have some value

 }

the syntax to check is

if(isset($_POST['vaiable'])){code goes here}

to check post is empty or not you can check by following syntax

If(empty($_POST['vaiable'])){code goes here}


if(!empty($_POST['varible'])) {
    $loginerr="";
} else  {
    $loginerr="Please check your entry.";
}

Use the empty function in PHP

if(empty($_POST['varible'])) {
    $loginerr = "Please Check your Entry.";
 } else {
    $loginerr = "";
 }

OR the isset function

if(!isset($_POST['varible'])) {
    $loginerr = "Please Check your Entry.";
 } else {
    $loginerr = "";
 }

Try this code

if(empty($_POST['varible']))
{
    $loginerr="Please Check your Entry.";
} 
else 
{
    $loginerr = "";
}
