Eval() should end with ;

<?php
$str = 'var str_array = ["aa", "bb"]';
$str = str_replace("var ", '$', $str); 
eval($str.";");
print_r($str_array);

Output:

Array ( [0] => aa [1] => bb )

But I don't know why you opt for this.

Post your javascript array as a JSON string via ajax and process it server-side.

Javascript

var str_array = ["aa", "bb"];
var request = $.ajax({
  url: "test.php",
  method: "POST",
  data: { myData : JSON.stringify(str_array) },
  dataType: "html"
});
request.done(function( msg ) {
  // ajax response
});
request.fail(function( jqXHR, textStatus ) {
  alert( "Request failed: " + textStatus );
});

PHP (test.php)

$json = $_POST['myData'];
$myDataArray = json_decode($json,true);
print_r($myDataArray);
