check if filename is like string in php for displaying images - php

Question

I am trying to get all images from a folder with php. It works fine. Now i wanna check if a certain image exists, and if so don't display it.
This is my basic code with works fine:
foreach (glob("Bilder/Spectrum/*.png") as $filename) {
$filenameDienst = explode("_", $filename);
echo "<a href='Dienste?d=".$filenameDienst[1]."#tabs-2'> <img class='loopimage' src='".$filename."'> </a>";
}
Now i wanna check for the image name "MB_default_Spectrum.png" and if it exists don't display it.
I have tried this:
foreach (glob("Bilder/Spectrum/*.png") as $filename) {
$filenameDienst = explode("_", $filename);
if ($filename != "MB_default_Spectrum.png") {
echo "<a href='Dienste?d=".$filenameDienst[1]."#tabs-2'> <img class='loopimage' src='".$filename."'> </a>";
}
}
But it did not work.. it is still displaying. What is wrong here? Thanks

glob returns an array of the paths matching the given pattern, not just the filenames. Looking at your code, the condition should then be:
if ($filename != "Bilder/Spectrum/MB_default_Spectrum.png")
Also, I personally prefer the following code (I find it cleaner):
$results = glob('path/to/dir/*.png');
foreach ($results as $filename)
// Skip specific file
if ($filename === 'path/to/dir/secretNuclearLaunchCodesAsImage.png')
continue;
echo $filename
}
