access and remove element from $data array codeigniter

Question

I have a associative array $data['arr1'] which is populated by a query. I need to iterate through the array , check each record for a specific value, and if the record is present , remove that record from the array. Here is my code:

    foreach($data['arr1'] as $key => $row) {

        // code for checking the value in a record. Cannot access the element here. I have 
           tried to print with these statements
        echo $data['arr1'] -> Firstname;
        echo $data['arr1'] [0];
        echo $data['arr1'][$key];
        echo [$key]; // gives me the values of index 0,1,2,3

        if(//check is true)
        {
            unset($data['arr1'][$key]);  //works fine, removes elements as needed
        }

    }

How can I access the element for checks? I think it is a combination of data['arr1'] and $key but i cannot find a correct combination. Also when I do print_r($data['arr1']) it prints the whole array correctly. as:

Array ( [0] => stdClass Object ( [Id] => 107 [assessmentTime] => 0000-00-00 00:00:00  [Gender] => 1 [DOB] => 2009-05-06 12:00:00 [Village] => Bhains [Tehsil] => 1 [UnionCouncil] => 2 [Snap] => 582864.jpg  [WhyWeDisable] => [HasDeleted] => 0 [CallerID] => 0 [vTime] => 0000-00-00 00:00:00 [CaseId] => 98 ) [1] => stdClass Object ( [Id] => 57 [FirstName] => ..............

Any help would be much appreciated.

first of all dont use echo on arrays, use print_r($array), var_export($array), or var_dump( $array ); but before these do echo '<pre>'; for formatting, so echo '<pre>'; var_export($data); — ArtisticPhoenix

prin_r($array) prints the whole array in one go. I need to print each record separately. How I do that? — Talha Rehman

print_r($array[$key]); unless it say stdclass, then it is an object and you use -> So you do print_r($data[0]->id); to get the id, basically print_r($data[0]); or print_r($data[1]); gets the object, then you access its property as standard with the arrow -> — ArtisticPhoenix

Try

foreach( $data as $obj ){
  echo $obj->id;
  ..etc.
}

You are confusing an array of objects with a multi-dimensional array.

or you can output them manually as

echo $data[0]->id;

If you only need to look at say the first one.

Anyway the give away here is this bit, when you print the whole array out.

 Array ( [0] => stdClass Object (

See where it says object. Arrays we access with [ key ] objects we access with $obj->property.
