निम्नलिखित में, " एक चर का नाम" पहचानकर्ता "है? int एक "कीवर्ड" है? 

  int main () {int i; }   
 मैं कीवर्ड, पहचानकर्ता, नाम, इकाई के बीच के अंतर को समझने में असमर्थ हूं।   
 
 
 चर के लिए  int i ,  int  प्रकार और  i  नाम है चर के लिए,  i  पहचानकर्ता होगा; हालांकि,  int  प्रकार के लिए पहचानकर्ता है।  
 प्रकार हो सकता है, लेकिन हमेशा नहीं, कीवर्ड होते हैं। पहचानकर्ता एक निश्चित वस्तु, प्रकार, आदि का संदर्भ देते हैं। नाम किसी ऑब्जेक्ट के एक उदाहरण का संदर्भ देते हैं। संस्थाएं किसी भी तरह के ऑब्जेक्ट को देखें, जिनमें बुनियादी प्रकार (इंट, चार, इत्यादि) शामिल हैं।

php - Creating canonical URLs with custom route-classes -

-
I am trying to implement the canonical url and to combine with custom route classes. URL-SACAME is something like this: / category-x / article / 123 / category-y / article / 123 I am creating a custom route - the expansion of the class Zend_Controller_Router_Route_Regex and checks that the article is 123 and the correct category-name is included in the URL. If the article is in 123 square-X and the user is reaching square-y, then I want to redirect to the correct URL. But there is no clear possibility to do this directly to the roads. What is the best practice approach here? I often do this in my action controller like something ... // Get / Category-Y / Article / 123 $ $ article- & gt; URL is generated, and it contains / category-x / article / 123 if (this-> --request-> getRequestUri ()! = $ Article-> URL) {return $ this- & gt; ; _helper-> Redirector-> GoToUrl ($ paragraph-> url); } In this example, $ article-> The url will need ...

I am trying to write a simple invoicing system. I want to use the Datetime Diff to calculate the cost of each invoice. I have so far: / * In this example $ dayLength and $ ratePerSec is not really the case, but now we use the hypotethical values ​​of 8.0 and 0.0054 Will * / $ date1 = new date time ("Time 1 Form Database", [DateTimeJonof Chase]); $ Date2 = new date time ("Time 2 Form Database", [Datetime Joneof Choice]); $ Diff = $ date2- & gt; Diff ($ date1); $ LenInSec = $ diff- & gt; Format ("% y") * 365 * $ dayLength * 3600 + $ diff- & gt; Format ("% d") * $ dayLength * 3600 + $ diff- & gt; Format ("% H") * 3600 + $ diff- & gt; Format ("% i") * 60 + $ diff- & gt; Format ("% s"); $ Cost = $ lenInSec * $ rate per second; When I try to output cost using $ lenInSec generated from the Deltaime Diff, I actually get weird results. Occasionally, in 1 and 3 out of 1 to 3 times, I get the...

In anticipation of a live scenario, I am creating my entire site, which has a 500 MHz processor with 256 MB A very large 100 MHz RAM I have loaded my database with 200k + rows of garbage data, trying to test my queries. I have seen - obviously because of this, a large display hit all my FAQ using the index, although some 15+ to join (using all indexes) using MySQL To enable 16MB cache, which brings down the query times to nothing but what results? With a dynamic website, I can not see how the cache can help completely when I allow unique queries such as a search feature. I am also using the eaccelerator for PHP. When I use the COUNT (*) total with multiple code JOIN and WHERE , then 10 + There are other queries. Other queries that only get the same line or two do at the same level when I had only a few lines I also noticed that almost 99% of the CPU in CPU CPU stress during a query Comes. Basically I do not know whether the software is on the fault or too much of the h...
