MIME Type Checking Fails

[subhuman]

My code works well. Though after 5 trials, it fails to check the mime type and the file size again. Even if I use the clearstatcache(), still the mime type checking fails beyond the 5 trials. If I restart Apache, everything still fails. What should I do?

<?php 
   $numberPROC = $HTTP_POST_VARS['numberPROC'];
   $namePROC = $HTTP_POST_VARS['namePROC'];
   $namePROC = ucwords($namePROC);
   $nameSYMP = $HTTP_POST_VARS['nameSYMP'];
   $nameTREAT = $HTTP_POST_VARS['nameTREAT'];
   $picPROC = $HTTP_POST_VARS['picPROC'];
   $nameAUTHOR = $HTTP_POST_VARS['name'];


   $pic_name_proc = $_FILES['picPROC']['name'];
   $image_MIME = $_FILES['picPROC']['type'];
   $errors = $_FILES['picPROC']['error'];

   $upload_directory = $HTTP_POST_VARS['store_dir'];

   $num_files = count($_FILES['picPROC']['name']);

   if (!is_dir($upload_directory)) {
   echo 'Directory Inexistent';
   exit();
   }

   $file_size_error = 0;

   for ( $idx2 = 0; $idx2 < $num_files; $idx2++ ) {
       if ($errors[$idx2] == 1 or $errors[$idx2] == 2) {
       $file_size_error++;
	   $size_error[] = $pic_name_proc[$idx2];
	   $size_treatment_error[] = $idx2 + 1;
	   }   

   }

   $mime_type_error = 0; 

   $file_types = array('.png');

   for ( $idx1 = 0; $idx1 < $num_files; $idx1++ ) {


   $ext = strrchr($image_MIME['$idx1'], '.');

   if (in_array($ext, $file_types)){
      continue;
   } else if ( $image_MIME['$idx1'] == ''){
      continue;
   } else {
      $mime_type_error++;
	  $mime_error[] = $pic_name_proc[$idx1];
	  echo $pic_name_proc[$idx1];
	  $mime_number_error[] = $idx1 + 1;
   }

   }

   $error1 = $size_error;
   $error2 = $mime_error;
   $error3 = $size_treatment_error;
   $error4 = $mime_number_error;

   $a1 = count($mime_error);
   $b2 = count(size_error);

   if ($a1 > 0 and $b2 > 0) {   

   echo 'there\\'s an error with the file uploads'.'<br />';
   echo 'you have specificied '.$numberPROC.' treatments';

echo '<br /><br /><br />';   
echo 'there\\'s an error with the file size on the uploaded file for treatments: ';	
echo '<br /><br /><br />';   	
while ( $element = each ($error1) ) {
$tempA = $element['key'];
$ilan1 = $tempA + 1;
$temp2 = $element['value'];

$temp4_el = each($error3);
$temp4 = $temp4_el['value'];

echo 'treatment '.$temp4.' - '.$temp2.'<br /><br />';
}  

echo '<br /><br /><br />';   
echo 'there\\'s an error with the mime type on the uploaded file for treatments: ';	
echo '<br /><br /><br />';   

while ( $element2 = each ($error2) ) {
$tempB = $element2['key'];
$ilan2 = $tempB + 1;
$temp1 = $element2['value'];

$temp5_el = each($error4);
$temp5 = $temp5_el['value'];

echo 'treatment '.$temp5.' - '.$temp1.'<br /><br />';
}  

   exit;

   } else {

   for ( $idx = 0; $idx < $num_files; $idx++ ) {

  if ( @copy ($HTTP_POST_FILES['picPROC']['tmp_name'][$idx],$upload_directory.$HTTP_POST_FILES['picPROC']['name'][$idx])) {
  //echo 'file ok';
  } else {
  //echo 'file not ok';
  @unlink($HTTP_POST_FILES['picPROC']['tmp_name'][$idx]);
  }
   }

?>

First of all, look at your code: see all the red? The red is a string.

If you're going to use single quotes inside of strings denotd by single quotes (i.e. echo 'there's a ...';), then you MUST ESCAPE THE QUOTES inside the string with a backslash, i.e. echo 'there\'s a ...';.

That error occurs a few times in your script; fix that and get back to us.

Also, do you need to do MIME-type checking? Why not just compare file extensions? Especially since MIME-types are browser-dependent; what happens when you get a stupid browser that sends incorrect/no MIME types?
