upload php check the maximum files size

STEP 4
Check the maximum file size

This validation help us prevent loading large files on the server.

First you must define next strings that have control de maxim for a uploading file  
 

$uploaded_size=$_FILES['userfile']['size'];
$maximum_size='182000';
the condition for validation is: 
elseif ($uploaded_size > $maximum_size)
{
echo '<center><font color=red>Your file<strong>"'.$_FILES['userfile']['name'].'"</strong> is too large.</font><br>maximum file size is "'.$maximum_size.'"';
} 

$uploaded_size=$_FILES['userfile']['size'];  - this string define the user files uploaded size 
$maximum_size='182000';  - this string is maximum size that you allowed for upload 

You can replace with any size ; 182000 is equivalent of 1,82 mb 

error message in this validation case is  :

Your file"example.JPG" is too large.
maximum file size is "182000" 



!! You can change the text but not this part "'.$_FILES['userfile']['name'].'"
