Как правильно извлечь значения из массива?

 
foreach($ex as $key=>$section) {
 
    foreach($section as $name=>$val) {
	        if ($name == ('FileName')) {
                $fname = $val;
		echo "$fname";
		}
 
		if ($name == ('FileSize')) {
                $fsize = $val;
		echo "$fsize";
		}
 
		if ($name == ('FileType')) {
                $ftype = $val;
		echo "$ftype";
		}
     }
}
 

foreach($ex as $key=>$section) {
$fname = $section['FileName'];
$fsize = $section['FileSize'];
 
}

 
foreach($exif as $key=>$section) {
    $fname = $exif['FILE']['FileName'];
    $fsize = $exif['FILE']['FileSize'];
 
 
	echo "$fname<br/>";
	echo "$fsize<br/>";
 
 
}
