{
Private $id;
Private $height;
Private $width;
Private $path;
function __construct ($path = "", $width =300, $height =500, $id = "MyChart")
{
Global $flash _chart;
$this->id= $id;
$this->height= $height;
$this->width= $width;
$this->path= $path;
if (! $flash _chart)
{
Echo ' <script type= ' text/javascript ' src= '. $path. ' Js/json/json2.js ' ></script> ';
Echo ' <script type= ' text/javascript ' src= '. $path. ' Js/swfobject.js ' ></script> ';
Echo ' <script type= ' text/javascript ' src= '. $path. ' Js/jquery-1.4.4.min.js ' ></script> ';
$flash _chart=true;
}
}

function __destruct ()
{
Unset ($this->id, $this->height, $this->width, $this->path);
}
function SetID ($id)
{
$this->id= $id;
}
function Setchart ($file, $info)
{
$TP =new TemplateData ($file);
Echo ' <script type= ' text/javascript ' > ';
echo "data_{$this->id}=". $TP->changeinfo ($info). ';
echo "function ofc_get_dataof{$this->id} () {return json.stringify (data_{$this->id});}";
echo "swfobject.embedswf". $this->path. " /open-flash-chart.swf ', ' $this->id ', ' $this->width ', ' $this->height ', ' 9.0.0 ', ' expressinstall.swf ', {' Get-data ': ' ofc_get_dataof{$this->id} '};
Echo ' </script> ';
}
}

3,templatedata class

Take a simple icon configuration from the already written txt text to load the class used: for example

Copy Code code as follows:

{
"title":
{
"Text": "(title)",
"Style": "{color: #FF0000; font-size:24px;}"
},
"Y_legend": {
"Text": "Iwebshop",
"Style": "{color: #736AFF; font-size:16px;}"
},

"Elements": [
{
"Type": "Line",
"Colour": "#736AFF",
"Text": "Registered user amount (person)",
"width": 1,
"Dot-style": {
"Type": "Solid-dot", "colour": "#a44a80", "Dot-size": 3,
"Tip": "#val # person <br> #x_label #"},
"On-show": {"type": "Shrink-in", "cascade": 1, "delay": 0.5},
"Values": [(Numbers)]
}
],

"X_axis": {
"Labels": {
"Labels": [(dates)]
}
},

"Y_axis": {
"Steps": (Steps),
"Max": (max)
}
}

This is the content of the class:

Copy code code as follows:

Class TemplateData
{
Public $substitution;
Private $templateFile;
function __construct ($filename)
{
$this->templatefile= @file_get_contents ($filename) or Die ("not find TemplateFile");
}
function __destruct () {
Unset ($this->templatefile, $this->substitution);
}
function Settemplatefile ($tfile)
{
$this->templatefile= $tfile;
}
function Gettemplatefile ()
{
return $this->templatefile;
}
function Replacereal ($matches)
{
Extract ($this->substitution, extr_overwrite);
Return Isset ($ $matches [1])? $ $matches [1]: $matches [1];
}
function Changeinfo ($subs)
{
$this->substitution= $subs;
Return Preg_replace_callback ((\w+)), Array (& $this, ' Replacereal '), $this->gettemplatefile ());
}

}

4, calling the code

Copy Code code as follows:

<!--//The mychat here is to show the place of flash, so can not be empty, change words to declare Flashchart class when the definition, detailed see Flashchart class-->
<div class= ' content_box ' ><div id= ' MyChart ' ></div></div>

<?php
Include ("flashchart.php");
Include ("templatedata.php");
$FC =new flashchart (' chart/', "100%", 320);
$infos =array (
' Numbers ' => ' 30000,10000,5000,6000000,700 ',
' Dates ' => ' "string 1\", \ "string 2\", \ "string 3\", \ "string 4\", \ "string 5\" ",
' Steps ' =>600000,
' Max ' =>6000000
);
$info =array ("title" => ' User Registration statistics ', ' numbers ' => $infos [' numbers '], ' dates ' => $infos [' dates '], ' steps ' =>$ infos[' steps ', ' Max ' => $infos [' Max ']];
$FC->setchart ("Chart/templatechart/user-add.txt", $info);

5, there is also a function of processing data, the query to convert the data set to OFC data

Copy Code code as follows:

/**
* @brief OFC data processing
* @params database to query the data set about the x,y axis
* @note Backstage
*/
/*
Public Function Init_count ($RS)
{

$numbers = ';
$dates = ';
$max = 0;
foreach ($rs as $row)
{

$numbers. = $row [' num ']. ', ';//y axis data
$dates. = "'. $row [' Month ']. '", ';//x axis data
if ($max < $row [' num ']) $max = $row [' num '];
}
$steps =ceil ($max/10);
$result = Array (
' Steps ' => $steps,
' Numbers ' => strlen ($numbers) >1? substr ($numbers, 0,-1): null,
' Dates ' => strlen ($dates) >1? substr ($dates, 0,-1): null,
' Max ' => $max + $steps
);
return $result;
}
