Escape Null in array

[ludo1960]

Hi there, first post here. Looking for a bit of help with array in an array:

[php]stdClass::__set_state(array( ‘nid’ => ‘1’, ‘node_title’ => ‘A4E Ltd’, ‘node_type’ => ‘guide_organisation’, ‘node_vid’ => ‘173’, ‘node_data_field_members_field_members_uid’ => array ( 0 => array ( ‘uid’ => NULL, ), ), )) [/php]

This is the array and I am performing a count on that array but my code seems to be counting Null as a value
here is my code:
[php]<?php
if (!is_null($data->node_data_field_members_field_members_uid))
print count($data->node_data_field_members_field_members_uid);
?>[/php]

Can anyone tell me where I’m going wrong?

Hi,

I think array key “node_data_field_members_field_members_uid” will always return NULL since, from the code given, no value has been given to that key. Here’s the simplified version of your code:

[php]<?php
$second_arr= array ( 0 => array ( ‘uid’ => NULL), );
//stdClass::__set_state(
$arr=array(
‘nid’ => ‘1’,
‘node_title’ => ‘A4E Ltd’,
‘node_type’ => ‘guide_organisation’,
‘node_vid’ => ‘173’,
‘node_data_field_members_field_members_uid’ => $second_arr,
);
print_r($arr);
echo “
”;
?>[/php]

Here’s the output:

Array ( [nid] => 1 [node_title] => A4E Ltd [node_type] => guide_organisation [node_vid] => 173 [node_data_field_members_field_members_uid] => Array ( [0] => Array ( [uid] =>  ) ) ) 

By the way, I can’t seem to get the point why you needed to give an array as a value to an array key… Can you describe to us what you wanted to do in that portion?

Happy to help,

Hi, many thanks for your reply.

The first example returns 1 as the result of the count function.

example 2 returns 0

[php]stdClass::__set_state(array( ‘nid’ => ‘19’, ‘node_title’ => ‘CAN (Community Ability Network)’, ‘node_type’ => ‘guide_organisation’, ‘node_vid’ => ‘191’, ‘node_data_field_members_field_members_uid’ => array ( ), )) [/php]

What’s going on? Just has to be something to do with the NULL…
