I was trying to upload images using the below code but it shows:
Parse error: syntax error, unexpected ';' in C:\xampp\htdocs\upload3.php on line 57
Here is what I have on line 57:
if ($file_size <= 0)
HandleError('File size outside allowed lower bound'); // Validate its a MIME Images (Take note that not all MIME is the same across different browser, especially when its zip file)
When I remove the above line from the below code, I get No Session was found. on the screen and nothing else comes. Does anyone have any Idea?
<?php
#check for session
if (isset($_POST['PHPSESSID']))
session_id($_POST['PHPSESSID']);
else if (isset($_GET['PHPSESSID']))
session_id($_GET['PHPSESSID']);
