I have a array, which comes from $_POST[] and can have other arrays in it as values, like:

array(
 'title' => 'Title',
 'data' => array(
             'hdr' => 'Header'
             'bdy' => 'Body'
           ),
  'foo' => array(1, 23, 65),
  ...
)

How can I sanitize all values of this big array? for eg. apply a strip_tags() to values like Title, Header, Body, 1, 23, 65 etc ?

Have a look at array_map

<?php  
$a = array(
'title' => 'Title',
'data' => array(
    'hdr' => 'Header',
    'bdy' => 'Body'
    ),
'foo' => array(1, 23, 65)
);

$b = array_map("strip_tags", $a);
print_r($b);
?>

Update for 2D array:

function array_map_r( $func, $arr )
{
    $newArr = array();

    foreach( $arr as $key => $value )
    {
        $newArr[ $key ] = ( is_array( $value ) ? array_map_r( $func, $value ) : ( is_array($func) ? call_user_func_array($func, $value) : $func( $value ) ) );
    }

    return $newArr;
}

Usage:

$a = array(
'title' => 'Title',
'data' => array(
    'hdr' => 'Header',
    'bdy' => 'Body'
    ),
'foo' => array(1, 23, 65)
); 

$ar =array_map_r('strip_tags', $a);
print_r($ar);

Note I found this just by searching the comments for Dimension

function set_val(array &$arr, $path,$val)
{
   $loc = &$arr;
   foreach(explode('.', $path) as $step)
   {
     $loc = &$loc[$step];
   }
   return $loc = $val;
}

A simple solution that comes to mind: combine array_filter and strpos;

$strings = array('Apple', 'Banana', 'Orange');
$substrings = array('pp', 'range');

$result = array_filter($strings, function($item) use($substrings) {
  foreach($substrings as $substring)
    if(strpos($item, $substring) !== FALSE) return TRUE;
  return FALSE;
});

To reset indices, you can use the array_values function.

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");

You actually should loop through arrays to combine them.

$combinedArray = array();
foreach ( $array1 as $key=>$value ) {
    $combinedArray[$key] = $array2[$key] . ' ' . $array1[$key];
}
