HighCharts导出选项会导致Codeigniter问题

Question

我正在使用CodeIgniter PHP框架和HighCharts lib edited by Ronan Gloo，

目前我正在使用此代码呈现图表：

$arDATA = $this->m_charts->get_ar_data($this->m_charts->chart_test);
$this->highcharts->from_result($arDATA)
                 ->set_type('bar')
                 ->set_title('Title1', 'Subtitle1')
                 ->add();
$data['charts'] = $this->highcharts->render();

var_dump($data['charts']);
//output : 
    <script type="text/javascript">
$(function(){
Highcharts.setOptions({"chart":{"backgroundColor":{"linearGradient":
[0,0,500,500],"stops":[[0,"rgb(255, 255, 255)"],
[1,"rgb(240, 240,255)"]]},"shadow":true},"plotOptions":{"series":
{"stacking":"normal"}}});

var chart_1 = new Highcharts.Chart({"series":[{"name":"n-2","data":
[200,150,350]}],"chart":{"renderTo":"hc_chart_1","type":"column"},"xAxis":
{"categories":["this","is a","graph"]},"title":{"text":"T1"},"subtitle":
{"text":"ST1_1"}});
});

为了将我的打印选项（下面的代码）包含在图表中，我尝试将其插入到$ data [＆＃39; charts＆＃39;]中，在系列之后使用以下内容展开字符串:(模式：＆＃ 39;]}]＆＃39;标记系列的结尾）

$charts_arr = explode('*', str_replace(']}],', ']}],*', $data['charts']));
$charts_arr[2] = $charts_arr[1];
$charts_arr[1] = exportingOptions($uc, $dt, $ap);

public function exportingOptions($userConnected, $dateTime, $authorizationPrint) {
        if ($authorizationPrint) {
            $print = "exporting: {chartOptions: {chart: {events: "
                    . "{load: function () {"
                    . "this.renderer.text('-CONFIDENTIEL-', 75, 325).attr({rotation: -25}).add();"
                    . "this.renderer.text('$userConnected', 315, 290).attr({rotation: -25}).add();"
                    . "this.renderer.text('$dateTime', 190, 310).attr({rotation: -25}).add()}}}},"
                    . "buttons: {contextButton: {menuItems: [{text: 'Print Chart',onclick: function() {"
                    . "this.renderer.text('-CONFIDENTIEL-', 350, 350).attr({rotation: -25,id:'1'}).add();"
                    . "this.renderer.text('$userConnected', 600, 300).attr({rotation: -25,id:'2'}).add();"
                    . "this.renderer.text('$dateTime', 470, 330).attr({rotation: -25,id:'3'}).add();"
                    . "this.print(); $(\#1).remove(); $(\#2).remove(); $(\#3).remove();}}, {"
                    . "text: 'Download PNG image', onclick: function() {this.exportChart({type: 'image/png'});}},{"
                    . "text: 'Download JPEG image', onclick: function() {this.exportChart({type: 'image/jpeg'});}},{"
                    . "text: 'Download PDF document', onclick: function() {this.exportChart({type: 'application/pdf'});}},{"
                    . "text: 'Download SVG vector image', onclick: function() {this.exportChart({type: 'image/svg+xml'});},separator: false}]}}},";
        } else {
            $print = "exporting: {enabled: false},";
        }
        return $print;
    }

但添加选项后图表不再显示。 如果需要，请不要犹豫，向我询问更多来源或解释。 欢迎提示：）
