Combine single and multidimensional array using php -

-

I have 2 arrays and I have both arrays.If match to array 1 array 2 , then I would like to keep 0 for that element.

array 1 

  $ weeks array = array ("P1", "P2", "P3", "P4"); Array ("P1", "123"), "1" => Array ("p1", "123"); array ("p2"); array 2  
 array2  
  $ dailyArr = array ("0" => , "125"), "2" => array ("P4", "126"));   
 After joining, I would like to be like the last array  
  $ finalArr = array ("0" => array ("p1", "Array (" p3 "," 0 ")," 3 "=> array (" p4 ", 123"), "1" => array ("P2", "125"), "2 "= & Gt;" 126 "));   
 So I would like to include  p3  in the final code.  
 Any indication / suggestions are very welcome Thanks in advance.   
 
 
 I do not know the shortest way to go there, but you can get all the p Compare weeks.  
 After receiving the differences, assign one, then sort them at the end.  
  $ weeksArr = array ("p1" "p2", "p3", "p4"); $ DailyArr = array ("0" = & gt; array ("p1", "123"), "1" => array ("p2", "125"), "2" => array ( "P4", "126")); $ End hour = $ daily; $ Temp = array_map (function ($ piece) {piece of return dollar [0];}, $ finals arrr); // Get $ diff = array_diff ($ weekout, $ temp) of all p; // Get the missing P. ($ $ $ $ w) as {$ finalArr [] = array ($ w, 0); // unavailable P} usort ($ finalArr, function ($ a, $ b) {// You do not need it, you do not care about order return strcmp ($ a [0], $ b [0]) ; // If you need to order them, P1, P2, P3, P4, then I think you need to sort it}); Echo '& lt; Pre & gt; '; Print_r ($ finalArr);

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...
