Question

I need to make an image gallery with a variable number of images. I’m making a loop that checks for a lot of image names, like image1, image2, image3 and so on.

I need to make a condition so that it doesn’t show a missing file icon if an image doesn’t exists. How can I check if the file exists and if true show it?

Thanks.

I think there are several PHP functions that will let you check for the existence of a file. One of them is file_exists:

bool file_exists ( string $filename )

Another function that you can use is is_file. According to the documentation:

Returns TRUE if the filename exists
and is a regular file, FALSE
otherwise.

So in your code you can do something like:

if (file_exists($fileName)) {
    // do stuff with file
}

// OR

if (is_file($fileName)) {
    // do stuff with file
}
