ryandward Posted October 25, 2011 Share Posted October 25, 2011 <? $i=1; $analysts[$i] = array(0=>'alpha'); $regions[$i] = array(0=>'beta'); $countries[$i] = array(0=>'gamma'); $provinces[$i] = array(0=>'delta'); $events[$i] = array(0=>'epsilon'); $selectable_document_elements = array ( 0=> analysts, 1=> regions, 2=> countries, 3=> provinces, 4=> events ); foreach($selectable_document_elements as $value) { echo $value; print_r($$value[$i]); echo "</br>"; } ?> I can't seem to call $$value[$i], however when I leave off the [$i] part print_r($$value); I get the individual elements... analystsArray ( [1] => Array ( [0] => alpha ) ) regionsArray ( [1] => Array ( [0] => beta ) ) countriesArray ( [1] => Array ( [0] => gamma ) ) provincesArray ( [1] => Array ( [0] => delta ) ) eventsArray ( [1] => Array ( [0] => epsilon) ) However, I would like to get the 1 part of the array, in this example. Is there a magic trick to calling variable arrays' individual elements?

watsmyname Posted October 25, 2011 Share Posted October 25, 2011 why are you assigning array to an array? you could simply do $analysts = array(0=>'alpha'); what is your desired result i didnt understand Link to comment https://forums.phpfreaks.com/topic/249756-how-to-call-elements-within-a-variable-array/#findComment-1281985 Share on other sites More sharing options...
ryandward Posted October 25, 2011 Author Share Posted October 25, 2011 I am just assigning an array to an array, because I am testing whether or not I can build a more generic multidimensional array foreach loop, as opposed to writing it for each selectable_document_element, in my case I have around 25. Obviously in the code, where I plan to place it, the multidimensional arrays will be pulled as variables from the database.

watsmyname Posted October 25, 2011 Share Posted October 25, 2011 I think this is what you want, please run it to confirm. <? $i=1; $analysts[$i] = array(0=>'alpha'); $regions[$i] = array(0=>'beta'); $countries[$i] = array(0=>'gamma'); $provinces[$i] = array(0=>'delta'); $events[$i] = array(0=>'iota'); $selectable_document_elements = array ( 0=> analysts, 1=> regions, 2=> countries, 3=> provinces, 4=> events ); foreach($selectable_document_elements as $value) { $val=$$value; echo "<pre>"; print_r($val[$i]); echo "</pre>"; echo "</br>"; } ?> Link to comment https://forums.phpfreaks.com/topic/249756-how-to-call-elements-within-a-variable-array/#findComment-1281990 Share on other sites More sharing options...
