I always get not exists even if the file is there. - What's wrong ?

 function checkedFile() { var fileName = 'file.php'; var checked = <?php $filename = $_GET["fileName"]; if (file_exists($filename)) { echo "'exists'"; } else { echo "'not exists'"; }?>; console.log(checked); } setInterval(function(){checkedFile()},500);

You need to do an honest request for api, and check the file on the server, not on the client

 function checkedFile() { var fileName = 'file.php?fileName=имя_файла'; fetch(fileName).then(result => result.text()) .then(console.log) } setInterval(function(){checkedFile()},500);

And on the server side already verify that the file exists

 filename = $_GET["fileName"]; if (file_exists($filename)) { echo "'exists'"; } else { echo "'not exists'"; }
