If you've already got a filepath of the form "ssh2.sftp://$sftp/path/to/file" you can just use unlink() on that path
(PECL ssh2 >= 0.9.0)
ssh2_sftp_unlink — Efface un fichier
Efface un fichier sur le système de fichiers distant.
Exemple #1 Effacement d'un fichier
<?php
$connection = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($connection, 'username', 'password');
$sftp = ssh2_sftp($connection);
ssh2_sftp_unlink($sftp, '/home/username/stale_file');
?>If you've already got a filepath of the form "ssh2.sftp://$sftp/path/to/file" you can just use unlink() on that pathFor some reasons, sometime it's not working. You can do like this instead:
unlink('ssh2.sftp://' . intval($sftp) . ssh2_sftp_realpath($sftp,".") . "./".$dstFile);
