php - $_GET does not work in some areas of the page -

-

so page has lot of include calls on different parts of page. of these includes have kind of function grabs $_get variables. of them work fine, except navigation file doesn't return when try grab variables.

nav.php

<? require_once("config.php"); require_once("functions.php"); ?>  <div id="nav">      <ul>          <? initializemainnav( $_get['page'] ); ?>      </ul>  </div>

inside function.php

function initializemainnav( $curpage ) {      // array ( slug, name ) of navigation items      $nav = array(         array( "", "home" ),         array( "case_studies", "investment case studies" ),         array( "current_inv", "current investments" ),         array( "about", "about mdig" ),         array( "management", "management" ),         array( "news", "news" ),         array( "services", "services" ) );      // print out each nav item, , highlight current page nav item      for( $i = 0; $i < count( $nav ); $i++ ) {          echo "  <li><a ";          if( $nav[$i][0] == $curpage )             echo "class=\"active\" ";          echo "  href=\"?page=" . $nav[$i][0] . "\">" . $nav[$i][1] . "</a></li> ";      }  }

$_get['page'] returns empty, tho works on other parts of page. guys see i'm doing wrong?

edit:

index.php header constant var defines path, located in config.php

<? require_once("config.php"); require_once("functions.php"); ?>   <? include(header); ?>  <body>      <div id="wrapper">          <div id="logo">              <a href="<? echo domain; ?>"><img src="<? echo images; ?>/logo.png" alt="<? echo company; ?>"></a>         </div>          <div class="clear"></div>           <? include(nav); ?>           <div id="content_wrapper">              <!-- find , display appropriate page -->             <? displaypage( $_get['page'] ); ?>          </div>          <div class="clear"></div>           <? include(footer); ?>      </div>  </body> </html>

i know doesn't give answer why isn't working, how following:

functions.php

function echomainnav($curpage) {    echo '<div id="nav"><ul>';    echo initializemainnav( $curpage );    echo '</ul></div>'; }

somepage.php

<? require_once("config.php"); require_once("functions.php"); ?>   <? include(header); ?>  <body>      <div id="wrapper">          <div id="logo">              <a href="<? echo domain; ?>"><img src="<? echo images; ?>/logo.png" alt="<? echo company; ?>"></a>         </div>          <div class="clear"></div>           <? echomainnav( $_get['page'] ); ?>           <div id="content_wrapper">              <!-- find , display appropriate page -->             <? displaypage( $_get['page'] ); ?>          </div>          <div class="clear"></div>           <? include(footer); ?>      </div>  </body> </html>

or better yet:

templates.php

define('templates_main_nav', '<div id="nav"><ul>%s</ul></div>');

functions.php

function getmainnav($curpage) {    return sprintf(templates_main_nav, initializemainnav( $curpage ) ); }

somepage.php

<?= getmainnav($_get['page']); ?>

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...
