php - Verify remote file exists with SplFileInfo -

-

i'm trying copy remote file server. before doing this, want test of file exists. following code not work, though have manually verified file exists on remote server. have php's allow_url_fopen set on. there missing? old procedural method file_exists() i'm looking replicate.

   //...    $fileinfo = new \splfileinfo($imagelocation);    if($fileinfo->isfile()) {       echo "doesn't exist";    } else {       echo "exists, copy file here";    }

there no equivalent of file_exists() splfileinfo class.

splfileinfo::isfile() different check, correlates is_file() function (they share underlying code).

you call file_exists() function on $imagelocation, provided references stream wrapper supports stat() functionality. wrappers such file://, phar:// , ftp:// (the latter partially) support this.

unfortunately http:// (and https://) wrapper does not support stat() calls. means file_exists(), , other functions call stat(), return false.
