php using variable as actual argument in php function -

-

Below is my code. In the first half of my code you will see variable $ $ question and $ line. I get the value when I echo out the $ Question and / or $ line [0]. However, at the bottom of the code, I try to use the variable in the add_textbox function as the actual argument for the use of these I am However, the add_textbox function is functioning as they are variable nulls. Someone can tell me what I am doing. 

  & lt ;? Php $ dbhost = 'localhost'; $ Uname = $ _POST ["uname"]; // *** Connection object $ connection = mysql_connect ($ dbhost, "bc572482", "dfdfdfs") or die (mysql_error ()); $ Dbname = "bc57"; Mysql_select_db ($ dbname) or die (mysql_error ());   
 // *** Select a random security question  
  // session_start (session) requires session variants; // resonance ($ _SESSION ["legitimate user"]. '' 
;); $ Uname = $ _ session ["legitimate user"]; // resonance ($ uname. '& Lt; br & gt;'); $ rq = array ('q1', 'q2', 'q3'); $ Rand_key = array_rand ($ rq, 1); // resonance $ rq [$ rand_key]; $ Question = $ rq [$ rand_key]; $ Qtoanswer = mysql_query ("Choose $ FAQ from user where uname = '$ uname'"); If (! $ Qtoanswer) {echo "query could not be run:" mysql_error (); Go out; } // echo ($ qtoanswer. '
'); $ Line = mysql_fetch_row ($ qtoanswer); // resonance ($ line [0]. Abc); display_security (); // To create myprint ($ text) for the Job Security page function {Print ("$ text \ n"); } // *** style function a bit (of add_style) {myprint ( "& lt; link rel = \" stylesheet \ "type = \" text / css \ "href = \" main.css \ "/ & gt ; "); // Mimperint ("& style; type = text / css> * {font-family: arial;} h3 {color: orange} "); } // *** Add a text box function add_textbox ($ label, $ name) {myprint ("$ label

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
