PHP圖形與谷歌圖表

這是有史以來第一次嘗試PHP圖表。我嘗試過使用各種可用的圖形模塊，但我無法獲取圖形。這就是我所追求的。我有一個頁面，點擊一個按鈕後，將打開一個新的PHP頁面，該頁面有代碼進行數據庫查詢&在該頁面上打印圖形（打開新頁面）。沒有理由，我終於決定堅持使用谷歌圖表製作圖表。在研究堆棧溢出問題時，我發現許多代碼被許多人認同，但是由於我在這個問題上的愚蠢，我無法實現。任何幫助，以獲得這一進展將不勝感激。PHP圖形與谷歌圖表

<?php

我建議：

<?php foreach($testArray as $key=>$value): ?> 
      ['<?php echo $key ?>', <?php echo $value ?>], 
      <?php endforeach; ?>

全功能drawChart：

function drawChart() { 

    <?php $testArray = array('AB_DATE1' => 10,'AB_DATE2' => 20,'AB_DATE3' => 30,'AB_DATE4' => 40,'AB_DATE5' => 50,'AB_DATE6' =>60,'AB_DATE7' => 70,); ?> 

    // Create our data table. 
    data = new google.visualization.DataTable(); 
    data.addColumn('string', 'Topping'); 
    data.addColumn('number', 'Slices'); 
    data.addRows([ 
     <?php foreach($testArray as $key=>$value): ?> 
     ['<?php echo $key ?>', <?php echo $value ?>], 
     <?php endforeach; ?> 
    ]); 

    // Set chart options 
    var options = {'title':'How Much Pizza I Ate Last Night', 
        'width':400, 
        'height':300}; 

    // Instantiate and draw our chart, passing in some options. 
    chart = new google.visualization.PieChart(document.getElementById('chart_div')); 
    google.visualization.events.addListener(chart, 'select', selectHandler); 
    chart.draw(data, options); 
    }

代替$ testArray的插入您的陣列。調整你的數組（數組（'AB_DATE1'=> 10，'AB_DATE2'=> 20，...））或循環。
