变量和preg_match PHP

Question

I am creating an app that displays only pictures where a certain profilename as been appended on to the beginning of the text.

for example 3 files in the folder are : Rogue-fastcar.jpg , John-girls.png, Petra-moneyNmore.jpg

I would like to return only the picture that has the profile that is stored within the session. So far its showing pictures from all users.

Thanks for the assistance, much appreciated.

foreach ($images as $index => $image) {
    $extension = strtolower(end(explode('.', $image)));
    $subject = $image;
    $profile = "$_SESSION["profile"]";
    $pattern = '/.$profile./';

    preg_match($pattern, $subject, $matches);



    if ($matches) {
        echo "Worse Behavior";
        if(!in_array($extension, $extensions)){
            unset($images[$index]);
        }else{
            $images[$index] = array(
                'full' => $this->path. '/' . $image,
                'thum' => $this->path. '/thumb/' . $image               
            );
        }
    }
}

Answer 1

the dots in your $pattern = '/.$profile./'; should be matching to any character that is not a newline. You probably want to try something like this:

$pattern= '/^$profile[-]{1}.*/' This should say you want to match anything that starts with the profile name, one dash, and then followed by anything else. (. is anything except the /n character and * is 0 or more of the previous pattern) Hope this helps.
