在柱状图中介绍php变量

如何在构建柱状图、折线图和饼图时引入php变量？

<?php $numero = 9; ?>
    <script type="text/javascript">
        var mes_I = "<?p h p echo $numero; ?>";
        var chart;
            $(function container_V () {
                var chart;
                $(document).ready(function() {
                    chart = new Highcharts.Chart({
                        chart: {
                            renderTo: 'container_V'
                        },
                        title: {
                            text: 'Média de Utilização de Animais'
                        },

                            categories: ["mes_III", "mes_II", "mes_I"]
                        },
                        tooltip: {
                            formatter: function() {
                                var s;
                                if (this.point.name) { // the pie chart
                                    s = ''+
                                        this.point.name +': '+ this.y +'%';

                        }]
                    });
                }); 
            });
    </script>

变量mes_I ok，包含值"9"。但是，当我输入给定的序列时，它不会出现。
