regex - With PHP filter a textfile into an A-Z listing -

-

I have a text file that reads: 

  9123 Bellevue Court 5931 Walnut Creek RD Andrew Bailey Chris Drew Earl Fred Gerald Henry Ida Jake Common Larry Manny Nomar Omar Perry Quest Raphael State Talmman Uruguayan Wickson Whale Xavier Yellow Zebra What do I need to do to make me an edge list? .. then:  
  # ABCDGGJKLMNOPQRSTUWWXYZ  
 
 And when you click on the letter, it will start with only one I will click on A, and if I click only on the # symbol, then only words starting with numbers are clicked. 
 
 I was thinking of using a regular expression to complete it but I did not want to create 27 different pages. So is there a way to call the letter at the end of the URL? Like doing something that 
 
  http: //mywebsite/directory.php? Letter = A

A very simple approach:

Text file Read in: 

  $ inputfile = file ('words.txt');

Then, after adjusting the input ( $ letters = $ _GET ['letter'] ), you can create a regex:

< Pre> $ regex = '/^'.$letter.'/' ';

and filter the rows you want to show: 

  $ result = preg_grep ($ regex, $ inputfile);

The rest is just a matter of outputting the good HTML (or whatever the output will be)

Keep in mind: When pages are often read, this is a database Very fast for files stored in

EDIT: Forget to mention: To get # to work, you also have a look at the caching system Should the problem be loaded sometime in the future. You need to add a line with the following: 

  if ($ letters == '#') $ letters = '[0-9]';

Get regex to work again.

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.

php - Multiple Select with Explode: only returns the word "Array" -

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option. However, when I select a new value and I save ... I only see the word "Array" and have not chosen anything else? & lt; Class = "amultiple" id = "& lt; php echo $ value ['id'] ;? gt;" name = "& gt; php echo $ value ['id'] ;; gt; []" Multiple = "multiple" size = "8" & gt; & Lt ;?

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
