I have these declared
$username = $this->users->getUsernameById($file->user);
$sessionuser = $this->session->userdata('username');
How would I go about comparing to the two values and if they match, execute code? I had
if ( $username == $sessionuser){
blalghalhalhalhllahblahhblahhblahhh
}
However, even when the two variables are the same, it doesn't seem to trigger the if statement. Did I do something wrong? maybe not ==, just =?
Use strcmp() function - or strcasecmp() for case-insensitive comparison.
if ( strcmp($username, $sessionuser) == 0) {
Generally speaking PHP is very forgiving when it comes to comparison operations because of the loosely typed dynamic nature of the language.
Try this to debug your code:
echo $username . '<br/>' . $sessionuser;
You may find that the values you are expecting aren't actually the values you're getting.
Another thing that I frequently have to do when stepping through my code is to place something like this:
echo 'got here';
exit;
immediately inside the if block to very whether it is that the block is not executing or whether it is the code within the block that is not executing as I expected it to.
