arrays - Splitting up a string - php -

i have array called $result, shown below:

array(1)      { ["response"]=> array(3)          { [0]=> array(1)              { ["list"]=> array(2)                  { ["category"]=> string(6) "(noun)"                  ["synonyms"]=> string(27) "chelonian|chelonian reptile" }              }            [1]=> array(1)              { ["list"]=> array(2)                  { ["category"]=> string(6) "(verb)"                    ["synonyms"]=> string(57) "capsize|turn turtle|overturn|turn over|tip over|tump over" }              }            [2]=> array(1)              { ["list"]=> array(2)                  { ["category"]=> string(6) "(verb)"                    ["synonyms"]=> string(29) "hunt|run|hunt down|track down" }              }           }      } 

i trying access ["synonyms"] element, , split each word , store in own string, or perhaps array of words. can see words separated | symbol.

i have tried following code, did not work (results did not display, explode did not work) :

$i=0;  foreach ($result["response"] $value)  {   foreach ($value["list"]["synonyms"] $temp)   {   $alternative[$i] = explode ("|", $temp);   $i++;   }  }  //output results  $j=0;  foreach ($alternative $echoalternative) { echo $j.": ".$echoalternative; $j++; } 

any ideas? guys.

you're trying iterate on string in interior foreach. try

foreach ($result["response"] $value)  {     $alternative[$i] = explode ("|", $value["list"]["synonyms"]);   $i++;   }
