Best practices when generating XML web services data for PHP -

-

I am currently using Fusioncharts in my project, for which XML should be in a specific format, data display

I have a PHP file named webservice.php that has many similar iterations below: 

  $ address = $ _SERVER [ 'PHP_SELF']; ... if ($ address == 'webService.php / fcf / last5pricechanges /') // // To query the MySQL db and export string in the browser to output the output variable to at least every line of XML Line output by line}

Outputed XML can look like this: 

   & Lt; Set name = "abc.com" value = "5" /> & Lt; / Graph & gt;   
 This is a maintenance nightmare to update this code, however afaik is that it will not be possible to transfer data using standard format - as in the rest of the form, Fusionerts require specific XML properties. Are there better ways to handle the above? Can I easily improve the humility and maintenance of my code?   
 
 
 I have some ideas that you can think of.  
  # 1  
 Using a template engine, like it might be a bit easier to maintain, it can at least get rid of XML from your PHP code. For example, you could create a template for the XML snippet you posted:  
   {/ Foreach} & lt; / Graph & gt; {/ Foreach}  
 
 and call it from PHP 
 
   
 
  # 2  
 You can create an object to help you manage the code. For example, to generate similar XML output, you could: 
 
  & lt ;? Php class graph {secure $ caption; $ Show_names protected; Protected $ decimal_complete; Protected $ bg_color; Protected $ set; Public function __construct ($ graph_id) {$ graph_result = mysql_query ("select caption, show_name, decimal_prescription_bug_guol, where something = 'some more'"); While ($ graph_row = mysql_fetch_assoc ($ graph_result)) {list ($ this-> caption, $ this-> show_name, $ this-> decimal_primation, $ this- & gt; bg_color) = $ graph_result; $ Set_result = mysql_query ("select name, set with value WHERE graph_id = {$ graph_row ['id']}"); While ($ set_row = mysql_fetch_assoc ($ set_result)) {$ this- & gt; Sets [] = $ set_row; }}} Public function fetch_xml () {$ output = '& lt ;?' . 'Xml version = "1.0" encoding = "UTF-8"?' . '& Gt;'; $ Output = "& Gt; Graph Caption = \" {$ this-> Caption} \ "showname = \" {$ this-> Show_name} \ "decimalprice = \" {$ this-> Decimal_paration} \ "bgcolor = \" {$ this- & gt; Bg_color} \ "& gt; \ n"; $ {$ Set-> Name} \ "value = \" {$ set-> Value} \ "/ $ {$ set-> \ n"; } $ Output. = "& Lt; / graph>"; Return $ output; }}? & Gt;  
 
 And call it in your main code: 
 
  & lt; Php $ address = $ _SERVER ['PHP_SELF']; If ($ address == 'web service .php / fcf / last5pricechanges /') {$ graph = new graph (1); $ Graph-> Fetch_xml (); }? & Gt; You can try to do something like this, but I suspect that maintenance will be of great help, because it is only for verbose As the echo method 
 
 and  # 4  
 ... No, I am everything :-) Hope that helps.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
