PHP MYSQL OPTIONAL MULTIPLE IMAGE UPLOAD -

i have html form image (multiple images) upload optional

<form action="upload.php" method="post" enctype="multipart/form-data"> <label>name:</label><input type="text" name="name"/></br> <label>brief:</label><input type="text" name="brf"/></br> <label>result:</label><input type="text" name="res"/></br> <label>photographs:</label><input type="file" name="file[]" accept="image" multiple="multiple" /></br> <input type="submit" name="submit" value="add"/></br> </form> 

i have image upload function working fine images , fails without images. tried split function

if (empty($_files['files']['tmp_name'])) { //my text function } else { //my images function } 

but no matter do, not call texonly() function

i've tried

if (empty($_files['files']['tmp_name'][$i]))  if (($_files['files']['tmp_name'] ==""))  if (empty($_files['files'.$i]['tmp_name']))  if (empty($_files['files']['size']))  if (($_files['files']['size'] == 0)) equels not equels is_uploaded_file ..etc..etc 

but nothing works me...any life saving

print_r($_files) output

with file

   array ( [files] => array ( [name] => array ( [0] => penguins.jpg ) [type] => array ( [0] => image/jpeg ) [tmp_name] => array ( [0] => c:\wamp\tmp\php94cf.tmp ) [error] => array ( [0] => 0 ) [size] => array ( [0] => 777835 ) ) ) 

without file

array ( [files] => array ( [name] => array ( [0] => ) [type] => array ( [0] => ) [tmp_name] => array ( [0] => ) [error] => array ( [0] => 4 ) [size] => array ( [0] => 0 ) ) ) 

your file tag name file

<label>photographs:</label><input type="file" name="file[]" accept="image" multiple="multiple" /></br> 

so check file not files

if (empty($_files['file']['tmp_name'])) { //my text function } else { //my images function }
