how to check for key in multidimentional array and then assign it's values

[eche]

Hi,

 

Could never really get my head around arrays, so can someone please help me understand what I'm missing here.

 

I have an array (size of it does not really matter - at best it will have around 20 elements). It's structure is

['code'] => (array [0] => 'name', [1] => 'description', [2] => 'status')

so example:

['100'] => (array [0] => 'test', [1] => 'this is a test code', [2] => 'allowed')

I want to be able to match code to the one that is being searched and if so, then assign name, description and status to variables for display. At the moment I have:

 

$search = $_GET['code'];
if (in_array($search,$array[$search])) {

$name = $array[$search][0];
$desc = $array[$search][1];
$status = $array[$search][2];

}

 

I get an error message of Warning: in_array() [function.in-array]: Wrong datatype for second argument in /var/... on line ... (the line corresponding to my in_array search)

 

I'm obviously doing something wrong, but what is it?

 

Thanks in advance  :-\

if i am not wrong then search value is in the key of the array and your array declaration is not right. I have changed the code so now and its working. I hope that array is in the right format.

 

Below is the code...

 

$array = array('100' => array(0 => 'test', 1 => 'this is a test code', 2 => 'allowed'));
$search = isset($_GET['code']) ? $_GET['code'] : 101;

if(array_key_exists($search, $array)){
$name = $array[$search][0];
$desc = $array[$search][1];
$status = $array[$search][2];
}else{
echo "Array key does not exists";
}

Hi,

 

Thanks - that would work. How could I change that code so that I may use a foreach statement to assign the values to this new array from a flat file database?

 

Something like?:

$results = file()

foreach ($results as $result) {

$explode  = explode("|",$result);
$item['code'] = explode[0];
$item['name'] = explode[1];
$item['desc'] = $explode[2];
$item['status'] = $explode[3];
}

foreach ($item as $key=>$value) {
$array = array($item['code'][$key] => array(0 => $item['name'][$key], 1 => $item['desc'][$key], 2 => $item['status'][$key]));
}

$search = isset($_GET['code']) ? $_GET['code'] : 101;

if(array_key_exists($search, $array)){
$name = $array[$search][0];
$desc = $array[$search][1];
$status = $array[$search][2];
}else{
echo "Array key does not exists";
}

 

Thanks.
