标题: [疑问]simple html dom + open flash chart
Below is my code for obtaining the data file :

  2. require_once("simple_html_dom.php");
  3. $html=file_get_html("http://finance.yahoo.com/q/hp?s=4707.KL+Historical+Prices");
  4. foreach ($html->find('td[class=yfnc_tabledata1]') as $e)
  5.         echo $e->innertext . '<br />' ;
  6.        
复制代码
This is my code for output the "preset" data into open flash chart :

  2. <?php
  3. include 'php-ofc-library/open-flash-chart.php';

  5. $month = array();
  6. $price = array();
  7. $month[] = 'Jan 4'; $price[] = 36.7;
  8. $month[] = 'Feb 2'; $price[] = 38.7;
  9. $month[] = 'Mar 1'; $price[] = 42.8;
  10. $month[] = 'Apr 1'; $price[] = 38.2;
  11. $month[] = 'May 3'; $price[] = 37.8;
  12. $month[] = 'Jun 1'; $price[] = 34.7;
  13. $month[] = 'Jul 1'; $price[] = 38.4;
  14. $month[] = 'Aug 2'; $price[] = 40.2;
  15. $month[] = 'Sep 1'; $price[] = 39.5;
  16. $month[] = 'Oct 1'; $price[] = 40.3;
  17. $month[] = 'Nov 1'; $price[] = 45.9;
  18. $month[] = 'Dec 1'; $price[] = 48.9;

  20. $chart = new open_flash_chart();

  22. $title = new title( 'Nestle (M) SDN BHD' );
  23. $title->set_style( "{font-size: 20px; color: #A2ACBA; text-align: center;}" );
  24. $chart->set_title( $title );

  26. $area = new area();
  27. $area->set_colour( '#5B56B6' );
  28. $area->set_values( $price );
  29. $area->set_key( 'Share Price(RM)/unit', 12 );
  30. $chart->add_element( $area );

  32. $x_labels = new x_axis_labels();
  33. $x_labels->set_steps(1);
  34. $x_labels->set_vertical();
  35. $x_labels->set_colour( '#A2ACBA' );
  36. $x_labels->set_labels( $month );

  38. $x = new x_axis();
  39. $x->set_colour( '#A2ACBA' );
  40. $x->set_grid_colour( '#D7E4A3' );
  41. $x->set_offset( false );
  42. $x->set_steps(1);
  43. // Add the X Axis Labels to the X Axis
  44. $x->set_labels( $x_labels );

  46. $chart->set_x_axis( $x );

  48. $x_legend = new x_legend( '1 year graph' );
  49. $x_legend->set_style( '{font-size: 20px; color: #778877}' );
  50. $chart->set_x_legend( $x_legend );

  52. $y = new y_axis();
  53. $y->set_range( 0, 60, 20 );
  54. $chart->add_y_axis( $y );

  56. echo $chart->toPrettyString();

请问有什么方法能把两个combine起来？也就是说我能利用simple_html_dom取回来的资料来output在我的open flash chart 上？由于我的flash chart‘s output是根据我preset data，但是我想要让flash chart’s output是依据我用simple-html-dom取回来的资料。请问要怎样才能做到呢？

只要你去摸索如何把 http://finance.yahoo.com/q/hp?s=4707.KL+Historical+Prices 所得到的資料编排成

# $month = array();
# $price = array();
# $month[] = 'Jan 4'; $price[] = 36.7;
# $month[] = 'Feb 2'; $price[] = 38.7;
# $month[] = 'Mar 1'; $price[] = 42.8;
# $month[] = 'Apr 1'; $price[] = 38.2;
# $month[] = 'May 3'; $price[] = 37.8;
# $month[] = 'Jun 1'; $price[] = 34.7;
# $month[] = 'Jul 1'; $price[] = 38.4;
# $month[] = 'Aug 2'; $price[] = 40.2;
# $month[] = 'Sep 1'; $price[] = 39.5;
# $month[] = 'Oct 1'; $price[] = 40.3;
# $month[] = 'Nov 1'; $price[] = 45.9;
# $month[] = 'Dec 1'; $price[] = 48.9;

這样的資料型态就可以了啊

把你的innertext 稍微处理就好～

谢谢两位，我是用for loop + array()来解决了。
  1. include 'php-ofc-library/open-flash-chart.php';
  2. $month = array();
  3. $price = array();
  4. require_once("simple_html_dom.php");
  5. $html=file_get_html("http://finance.yahoo.com/q/hp?s=4707.KL+Historical+Prices");
  6.        
  7.         for ($i=336; $i>=0; $i-=7)
  8.         {
  9.                 $month[] = $html->find('td[class="yfnc_tabledata1"]', $i)->innertext;
  10.                 }
  11.        
  12.         for ($j=340; $j>=4; $j-=7)
  13.         {
  14.                 $price[] = floatval($html->find('td[class="yfnc_tabledata1"]', $j)->innertext);
  15.                
  16.                 }
