Your ajax is wrong, it should be:

var a = "test";
$.ajax({
    type: "POST",
    url: "search.php",
    dataType: "json",
    data: {a:a},
    success: function(data) {
        alert('Successfully');
    },
    error: function(data) {
        alert('Failed');
    }
});

If you're requesting a JSON, use the $.getJSON from jQuery, it's aready parse the JSON into a JSON object for you.

Seems that you're not return an actual JSON from server, maybe this is what is causing the error.
If you're seeing the 'Failed' message probably the problem is a 500 error which is a server error.

Try this code above.

Javascript:

var a = "test";

$.getJSON("search.php", {
  a: a
}, function (json) {
  console.log(json);
});

PHP:

<?php
$pictures = ["img1"];
echo json_encode($pictures);

The only way to this not work, is if you have a huge mistake on you webserver configuration.

I refined your code slightly and it works. 

    var a = "test";
    $.ajax({
        type: 'POST',
        url: 'search.php',
        data: 'a=' + a,
        dataType: 'json',
        cache: false,
        success: function (result) {
          alert('Successful');  
        },
        error: function (result) {
          alert('Failed');
        }
    });
