$.ajax({
  url: "your_php_script.php",
  method: "POST",
  data: { variable: jsVariable },
  success: function(response) {
    console.log(response);
  }
});

$phpVariable = $_POST['variable'];
echo $phpVariable;

<form action="your_php_script.php" method="POST">
  <input type="hidden" name="variable" id="hiddenVariable">
  <input type="submit" value="Submit">
</form>

var jsVariable = "Hello";
document.getElementById("hiddenVariable").value = jsVariable;

$phpVariable = $_POST['variable'];
echo $phpVariable;

var jsVariable = "Hello";
var url = "your_php_script.php?variable=" + encodeURIComponent(jsVariable);
window.location.href = url;

$phpVariable = $_GET['variable'];
echo $phpVariable;
