php - getimagesize() expects parameter 1 to be string, array given -

i using getimagesize validate image type don't know how write script multiple file. basically, have form allow upload of multiple image files below.

  <input type="file" name="photo[]" class="file" />   <input type="file" name="photo[]" class="file" />   <input type="file" name="photo[]" class="file" /> 

then using validate , send via phpmailer.

<?php ob_start(); require("class.phpmailer.php");  $errors = array();  if ('post' === $_server['request_method']) {     $firstname           = sanitize($_post['firstname']);     $lastname           = sanitize($_post['lastname']);     $email                 = sanitize($_post['email']);      if (empty($firstname))     {         $errors['firstname'] = "please provide first name.";     }     if (empty($lastname))     {         $errors['lastname'] = "please provide last name.";     }     if (!filter_var($email, filter_validate_email))     {         $errors['email'] = "please provide valid email address.";     }      if (count($errors) === 0)     {   $imageinfo = array();   $my_files = $_files['photo']['tmp_name'];   foreach($my_files $single_file) {   if(!empty($single_file)) {   $imageinfo[$single_file] = getimagesize($single_file);   if ($single_file['mime'] != 'image/png' && $single_file['mime'] != 'image/jpeg')   { echo "invalid image file";   exit();   }  }   }   foreach($_files['photo']['tmp_name'] $photo)  if(!empty($photo)) { $mail->addattachment($photo);   $message = 'some message';  $mail = new phpmailer();  $mail->setfrom($email); $mail->addaddress($from);  $mail->subject  = "submitted"; $mail->body     = $message; $mail->wordwrap = 50; }  $mail->send();  header("location: thankyou.php"); exit();      }}  function sanitize($value) {     return trim(strip_tags($value, $problem='')); } ?> 

i getting error message of warning: getimagesize() expects parameter 1 string, array given know because of form passing array. how change script work multiple files/arrays? please help. thx.

there more 1 file in $_files['photo']['tmp_name'] array.

the getimagesize() designed accept 1 file.

so need pass each files function

$imageinfo = array(); $my_files = $_files['photo']['tmp_name']; foreach($my_files $single_file) {   if(!empty($single_file)) {     $imageinfo[$single_file] = getimagesize($single_file);   } }  print_r($imageinfo); // have info of files in array. 

or can try

$imageinfo0 = getimagesize($_files['photo']['tmp_name'][0]); $imageinfo1 = getimagesize($_files['photo']['tmp_name'][1]); $imageinfo2 = getimagesize($_files['photo']['tmp_name'][2]); 

.... , on..
