Example print_r($myarray)

Array
(
    [0] => Array
    (
        [id] => 6578765
        [name] => John Smith
        [first_name] => John
        [last_name] => Smith
        [link] => http://www.example.com
        [gender] => male
        [email] => email@domain.com
        [timezone] => 8
        [updated_time] => 2010-12-07T21:02:21+0000
    )
)

Question, how to get the $myarray in single value like:

echo $myarray['email'];  will show email@domain.com

Look at the keys and indentation in your print_r:

echo $myarray[0]['email'];

echo $myarray[0]['gender'];

...etc

Here is another way. No intermediate variables are saved.

We used this to de-duplicate results from a variety of overlapping queries.

$input = array_map("unserialize", array_unique(array_map("serialize", $input)));

When you set cell values individually, you have the option of setting the datatype explicitly, but when you use the fromArray() method, you don't have this option.

However, by default, PHP uses a default value binder to identify datatypes from the values passed, and set the cell datatype accordingly. This default behaviour is defined in a class /PHPExcel/Cell/DefaultValueBinder.php.

So you can create your own value binder, as described in the PHPExcel Documentation, that would set every value as a string datatype.

Something like:

class PHPExcel_Cell_MyColumnValueBinder extends PHPExcel_Cell_DefaultValueBinder implements PHPExcel_Cell_IValueBinder
{
    protected $stringColumns = [];

    public function __construct(array $stringColumnList = []) {
        // Accept a list of columns that will always be set as strings
        $this->stringColumns = $stringColumnList;
    }

    public function bindValue(PHPExcel_Cell $cell, $value = null)
    {
        // If the cell is one of our columns to set as a string...
        if (in_array($cell->getColumn(), $this->stringColumns)) {
            // ... then we cast it to a string and explicitly set it as a string
            $cell->setValueExplicit((string) $value, PHPExcel_Cell_DataType::TYPE_STRING);
            return true;
        }
        // Otherwise, use the default behaviour
        return parent::bindValue($cell, $value);
    }
}

// Instantiate our custom binder, with a list of columns, and tell PHPExcel to use it
PHPExcel_Cell::setValueBinder(new PHPExcel_Cell_MyColumnValueBinder(['A', 'B', 'C', 'E', 'F']));

$objPHPExcel = new PHPExcel();
$objPHPExcel->getActiveSheet()->fromArray($dataArray,null,"A2");

If subarray contain one element always you could chage that value using array_map and current function.

$arr=array(array(8159),array(8140),array(8134),array( 8168),array(8178),array( 8182),array( 8183));
$arr1=array(array(8159),array(8140),array(8134),array(8165),array(8166),array(8167),array( 8168));
$arr2=array(array(566),array(265),array(8134),array(655),array(8166),array(665),array( 8168),array(656),array( 989),array( 989));
$arr3=array(array(8159),array(8140),array(8134),array(8165),array(8166),array(8167),array( 8168));

$arr = array_map('current', $arr);   // getting first value of subarray
$arr1 = array_map('current', $arr1);
$arr2 = array_map('current', $arr2);
$arr3 = array_map('current', $arr3);
print_r($arr3);
// Array
// (
//     [0] => 8159
//     [1] => 8140
//     [2] => 8134
//     [3] => 8165
//     [4] => 8166
//     [5] => 8167
//     [6] => 8168
// )

$res= array_intersect($arr,$arr1,$arr2,$arr3);
print_r($res);
// Array
// (
//    [2] => 8134
//    [3] => 8168
// )

There's a lot been written about PHPExcel and memory use, and I'm not going to repeat it all here.

Try reading some of the threads on the PHPExcel discussion board discussing the issue, such as this one; or previous answers here on SO such as this one or this one
