note 42045 added to language.types.array

Here is a trick I couldn't find in books. Say we have this nested array: $arr = array(); $arr[] = array('term' => 'apple', 'definition' => 'fruit'); $arr[] = array('term' => 'cucumber', 'definition' => 'vegetable'); $arr[] = array('term' => 'banana', 'definition' => 'fruit'); how do we find the values of all terms? You cannot do this by referencing say, 'apple' term as $arr[0]['term']. The way to do is by simply typing $arr['term'] in foreach loop - yes, PHP will go inside the nested arrays, checking for 'term' values! Example: foreach ($arr as $item) { echo $item['term'].'=>'.$item['definition'].'<br />'; } will return: apple=>fruit cucumber=>vegetable banana=>fruit as intended. ---- Manual Page -- http://www.php.net/manual/en/language.types.array.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+42045 Delete -- http://master.php.net/manage/user-notes.php?action=delete+42045&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+42045&report=yes Search -- http://master.php.net/manage/user-notes.php
