How do I get an image without knowing the length of it? for example:
Image name is moon , but I do not know the extension and when I try to use php commands of the error and says it could not find the file
How can I get a file by name only without knowing the extension?
Try using the glob function
foreach (glob("lua.*") as $archive) {
// faça sua mágica aqui
}
Or you can also limit extensions
glob("lua.{jpg,png}")

You can search all files in a directory using the scandir function, and then comparing the name using the pathinfo function, using the PATHINFO_FILENAME . Feel free to change this script to your needs.
<?php
$dir = '/tmp';
$dirFiles = scandir($dir);
$search = 'lua';
foreach($dirFiles as $file) {
if (is_file($dir.'/'.$file) AND pathinfo($dir.'/'.$file, PATHINFO_FILENAME) == $search) {
// aqui você pode fazer o que quiser
echo "Arquivo encontrado: ".$dir.'/'.$file;
}
}
?>
