javascript - JQuery AJax Result Echo PHP -

i must check result of ajax same php variable value. there anyway this?

thank in advance help.

my ajax html:

<?php $x = '<p id="ip"></p>'; $y = '2_2_1_3';  if($x == $y){   echo $x; } ?>  <a id="input" href="#">get value<input type="hidden" value="2_2_1_3"></a>  <script src="https://code.jquery.com/jquery-1.10.2.js"></script> <script> jquery(document).ready(function(){   $("#input").on("click", function(){     $.ajax({       type: 'post',       url: "ip2.php",        data:'ip=' + $(this).parent().find('input').val(),       success: function(data){       $("#ip").html(data);       }     });   }); }); </script> 

the php script:

<?php if($_post['ip'] >= 0){   $ip = $_post['ip'];     echo $ip;   } ?> 

$x = '<p id="ip"></p>'; $y = '2_2_1_3'; if($x == $y){ // never true because $x diferent of $y echo $x;  //so never print out } 

and won't have element id="ip" print result ajax

success: function(data){   $("#ip").html(data);   } 

for work try this:

<?php $x = '<p id="ip"></p>'; $y = '2_2_1_3'; echo $x; ?>
