PHP - In_array Problem

I can't seem to understand why in_array is NOT finding the 'needle'.

php file:
Code: [Select]
<?PHP
$search = "WS11";
$valid_codes = file("outcode2.txt");
if(in_array($search, $valid_codes)){
echo "yes";
}else{
echo "No";
}
echo $search . "<hr>";
echo "<PRE>";
print_r($valid_codes);
echo "</pre>";
?>

outcode2.txt:
Code: [Select]
WS10
WS11
WS12
WS13
WS14
WS15

WS11 is in the outcode2.txt
It is not an issue of case.
Perhaps my old eyes just keep missing the problem.
Any help is appreciated.

I can't access an array value in a multidimensional array.  The if should be echoing true.  $news['companyid'] is equal to 1, but I must not be using in_array correctly.

Code: [Select]
echo '<pre>';
print_r($own_company);

if (in_array($news['companyid'], $own_company))
{
echo "true";
}

Output
Array
(
    => Array
        (
            [companyid] => 1
            [companyname] => Oaysus
            [companytag] =>
            [companywebsite] => http://oaysus.com
            [country] => 1
            [state] => 0
            [city] =>
            [industry] => 4
            [stage] => 2
            [capitalrequested] =>
            [guestviews] => 0
            [iviews] => 3
            [eviews] => 3
        )

Hi folks!

I have two arrays:

1) print_r($users1); 
Array ( => 1 [1] => 2609 [2] => 2612 [3] => 2620 [4] => 2621 [5] => 2624 [6] => 2627 [7] => 2629 )

2) print_r($users2); 
Array ( => 1 [1] => 2609 [2] => 2610 [3] => 2611 [4] => 2612 [5] => 2617 [6] => 2618 [7] => 2619 [8] => 2620 [9] => 2621 [10] => 2624 [11] => 2625 [12] => 2626 [13] => 2627 [14] => 2628 [15] => 2629 )

now why does nothing return when I use in_array?

if(in_array($users1,$users2)) 
  return true;

all values in $users1 is in $users2...

Please help, need help fast!

Thank you

Hello:

I'm trying to compare two mySQL result sets (for determining when to check a checkbox in an input form).

$dataList['listname'] is my needle. (only the checkboxes I want to check)
$data['listname'] is my haystack (the list of all checkboxes)


Code: [Select]
while($dataList = mysql_fetch_array($runListQuery))
{
$checked = '';
echo $data['listname'].'<br /><br />';
echo $dataList['listname'].' :: ' .  $data['listname'] . '::' . (string)array_search ($dataList['listname'],$data['listname'],false) .'<br>';
echo in_array($dataList['listname'],$data['listname']);
echo '<br>----------------------<br>';
var_dump($data['listname']);
echo '<br>----------------------<br>';
var_dump ($dataList['listname']);
echo '<br>----------------------<br>';
if(in_array($dataList['listname'],$data['listname'],false)) {
echo 'found!!!!!!!!!!!';
$checked = 'CHECKED';
}
echo '<tr>';
echo '<td>' . $dataList['listname'] . '</td>';
echo '<td><input type="checkbox" '. $checked . ' name="'.$dataList['listname'].'" />';
echo '</tr>';
}
I never hit the 'found!!!!!!!!' string.  My output is below:

Code: [Select]
list-charter

halwasiya :: list-charter::

----------------------
string(12) "list-charter"
----------------------
string(9) "halwasiya"
----------------------
list-charter

halwits :: list-charter::

----------------------
string(12) "list-charter"
----------------------
string(7) "halwits"
----------------------
list-charter

list-charter :: list-charter::

----------------------
string(12) "list-charter"
----------------------
string(12) "list-charter"
----------------------

I have a section in one of my scripts that checks for a value in array and the value doesn't exist in the array then it add it.  This works fine for single array but not for mulit-dimensional arrays.  Has anyone had a similar problem and knows a good solution?

Code: [Select]
if(in_array($words[$i], $searchWords)){
    //Do nothing
}else{
    $searchWords[] = $words[$i];
}
