                   // unlink($uploadPath . $filename_with_extension);
                }

CodePudding user response：

Check your error message - path contains quotes. For some reason your $names[$i]->pdf contains quotes inside.

So you should fix what is adding additional quotes in $names[$i]->pdf or trim it to exclude quotes. Also before unlinking check if file exists

for ($i = 0; $i < $names_size; $i  ) {
    $uploadPath = 'public/repair_pdfs/';

    $filename_with_extension = trim($names[$i]->pdf, "'");

    if (!empty($filename_with_extension) && file_exists($uploadPath . $filename_with_extension)) {
        unlink($uploadPath . $filename_with_extension);
    } else {
        $filename_with_extension = null;
    }
    // unlink($uploadPath . $filename_with_extension);
}
