Question

Answer 1

+1 A:

If $a is the array that's passed, $a[76][0]['id'] should give '76' and $a[76][1]['id'] should give '81' , but I can't test as I don't have PHP installed on this machine.

$a[76][0]['id'] returns NULL

streetparade 2009-10-09 14:46:26

Simplify the problem: `$a = array('foo');` `$a[0]` should be `'foo'`. `$a = array(76 => 'foo');` `$a[76]` should be `'foo'`. `$a = array(76 => array('foo');` `$a[76][0]` should be `'foo'`... So on and so forth.

sorry but that makes it much more complicatet

Shouldn't `['languages']` be in there somewhere?

R. Bemrose 2009-10-09 14:53:36

There is one 'Deutsch' is the language

The array in the question is very poorly formatted and hard to read. The 76 key is within the 'languages' array. The inactiveTags is a parent key with its own set of nested arrays. See my answer for more info.

Answer 4

A:

Regarding your code: It's slightly hard to read... If you want to try to view it all in a php array format, just print_r it. This might help:

<?php
$a =
array(  

  'languages' =>    

  array (   

  76 =>      

 array (       'id' => '76',       'tag' => 'Deutsch',     ),   ),    'targets' =>    
 array (     81 =>      
 array (       'id' => '81',       'tag' => 'Deutschland',     ),   ),    'tags' =>    
 array (     7866 =>      
 array (       'id' => '7866',       'tag' => 'automobile',     ),     17800 =>      
 array (       'id' => '17800',       'tag' => 'seat leon',     ),     17801 =>      
 array (       'id' => '17801',       'tag' => 'seat leon cupra',     ),   ),   
'inactiveTags' =>    
 array (     195 =>      
 array (       'id' => '195',       'tag' => 'auto',     ),     17804 =>      
 array (       'id' => '17804',       'tag' => 'coupès',     ),     17805 =>      
 array (       'id' => '17805',       'tag' => 'fahrdynamik',     ),     901 =>      
 array (       'id' => '901',       'tag' => 'fahrzeuge',     ),     17802 =>      
 array (       'id' => '17802',       'tag' => 'günstige neuwagen',     ),     1991 =>      
 array (       'id' => '1991',       'tag' => 'motorsport',     ),     2154 =>      
 array (       'id' => '2154',       'tag' => 'neuwagen',     ),     10660 =>      
 array (       'id' => '10660',       'tag' => 'seat',     ),     17803 =>      
 array (       'id' => '17803',       'tag' => 'sportliche ausstrahlung',     ),     74 =>      
 array (       'id' => '74',       'tag' => 'web 2.0',     ),   ),    'categories' =>    
 array (     16082 =>      
 array (       'id' => '16082',       'tag' => 'Auto & Motorrad',     ),     51 =>      
 array (       'id' => '51',       'tag' => 'Blogosphäre',     ),     66 =>      
 array (       'id' => '66',       'tag' => 'Neues & Trends',     ),     68 =>      
 array (       'id' => '68',       'tag' => 'Privat',     ),   ), );

 printarr($a);
 printarr($a['languages'][76]['tag']);
 parintarr($a['targets'][81]['id']); 
 function printarr($in){
 echo "\n";
 print_r($in);
 echo "\n";
 }
 //run in php command line php path/to/file.php to test, switching otu the print_r.
