如何将数组php转换为javascript数组

Question

I have some problem about parsing array php to javascript array, I use json_encode but I get error like

Uncaught SyntaxError: Unexpected number

This my code :

<?php 
        $b=array();
        $a=array();
        $pat = 0;
        for($i = 0; $i<15;$i++)
        {
            if($pat == 5)
            {
                ini_set('memory_limit', '-1');
                array_push($b,$a);
                $a = array();
                $pat = 0;
            }
            ini_set('memory_limit', '-1');
            array_push($a,$i.'-1');
            $pat = $pat +1;
        }

    ?>

$(document).ready(function() {

        $('#example').DataTable( {
            serverSide: true,
            ordering: false,
            searching: false,

            ajax: function ( data, callback ) {
                var out1 = "<?php echo json_encode($b) ?>";
                var out = [["0-1","0-2","0-3","0-4","0-5"],["1-1","1-2","1-3","1-4","1-5"]];

                console.log(out);

                setTimeout( function () {
                    callback( {
                        // draw: data.draw,
                        data: out,
                        recordsTotal: 5000000,
                        recordsFiltered: 5000000
                    } );
                });
            },

        } );
    } );

I want result like variable out, what can I do to fix this bug thanks, and I'm sorry for my bad English
