How to escape a period for php and mysql question? -

-

OK, that's what I am doing, I am trying to avoid this period so that I can 8em would add font and for example in my code, instead of a simple number font, a 2.5M font I tried to avoid this script in three different ways but I think I am doing it wrong.

Here's my font size in the script. 

  $ min_size = 1; // $ 8 $ max_size = 2; // change 2.5

and here is the part of the script that displays the font size. 

  $ tags = tag_info (); $ Minimum_count = minutes (array_values ​​($ tag)); $ Maximum_ count = maximum (array_values ​​($ tag)); $ Spread = $ max_mount - $ minimum_count; If ($ spread == 0) {$ spread = 1; } $ Cloud_html = ''; $ Cloud_tags = array (); Forex Currency ($ tag = $ gt; = count as $ tag) {$ size = $ min_size + ($ count - $ minimum_count) * ($ max_size - $ min_size) / $ spread; $ Cloud_tags [] = '& lt; A style = "font-size: 'floor ($ size).' Em '.' 'Class =" tag_cloud "href =" http://www.example.com/tags/' $ Tag. ' / '.' "Title =" \ '". $ Tag '\' Returned the count. $ Count '' & Gt; '. Htmlspecialchars (stripsash ($ tag)) '& lt; / A & gt; '; } $ Cloud_html = Join ("\ n", $ cloud_tags). "\ N"; Return $ cloud_html; }

floor ($ size) $ Size to 2.5 to 2 and 0.8 to 0 . Why are you using floor ?

-
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.

I do not understand why this script does not work. It has something to do within AJAX PostScript / Function. Right now, when I submit my form, it runs php code on the same page. What it should do, send the values ​​of the form for Project_Azax.fp, then there will be a refund of success on the page which is correct or false. $ (document) .ready (function () {$ ('div # didIt').
