search array of field values for one of them in drupal-6

So, I have got a node reference field, which can have multiple values and I'm attempting to compose a php code, which will check all values of that field for a certain value i want and print a text if it finds it. I want to do it in views php field and this is the code i have came up with so far:

<?php
$node = node_load($data->nid);
print $data->nid . '<br>';
if(in_array('Yog [nid:1315]', $node->field_ref_oznajomenieni)) {
print 'yoog';
}
else {
print 'niemanic';
}
?>

I'm somewhat bad in PHP, but: The node_load() works fine and $data->nid returs node id for every row of my view. This is confirmed by print $data->nid . '|';

Now, the if function is supposed to do what i want, search the array of values for something in the node reference field and print something too. I'm not sure if i should search for the nid of the referenced node, its title or how i put it in the code, whatever i try, i get the print 'niemanic'; of the else{}

How should i do it exactly, please?

To make it clear: The code is to search for a value in a node reference field and print something only if it is found.

one way:

// less RAM usage
$node = node_load($data->nid);
$napis = '';
foreach ($node->field_ref_oznajomenieni as $value) {
if ($value[nid] == '1315') {
$napis = 'Yog';
}
// if (!($napis)) $napis = 'niemanic'; // for testing purpose
}
print $napis;

another way: (untested, may lack some brackets)

// flattened matrix way
$plaskatablica = array();
foreach ($node->field_ref_oznajomenieni as $value) {
$plaskatablica[] = $value[nid];

if(in_array('1315', $plaskatablica)) {
print 'Yog';
}
}

Here is what i have figured by myself:

$node = node_load($data->nid);
$ii = 0;
foreach ($node->field_ref_oznajomenieni as $value) {
if(in_array('1315', array_values($node->field_ref_oznajomenieni[$ii]))) {
print 'Yog';
}
++$ii;
}

This is print_r($node->field_ref_oznajomenieni); output of an example field:

Array ( 
[0] => Array ( [nid] => 1320 ) 
[1] => Array ( [nid] => 1315 ) 
[2] => Array ( [nid] => 1518 ) 
[3] => Array ( [nid] => 1519 ) 
[4] => Array ( [nid] => 1525 ) 
)
