[疑问]simple html dom + open flash chart

alanlai12345

Below is my code for obtaining the data file :

1. 
   
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.

This is my code for output the "preset" data into open flash chart :

1. 
   
2. <?php
   
3. include 'php-ofc-library/open-flash-chart.php';
   
4. 
   
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;
    
19. 
    
20. $chart = new open_flash_chart();
    
21. 
    
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 );
    
25. 
    
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 );
    
31. 
    
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 );
    
37. 
    
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 );
    
45. 
    
46. $chart->set_x_axis( $x );
    
47. 
    
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 );
    
51. 
    
52. $y = new y_axis();
    
53. $y->set_range( 0, 60, 20 );
    
54. $chart->add_y_axis( $y );
    
55. 
    
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.                 }
