Check if File Exists

See more SFTP Examples

Demonstrates how to check to see if a file exists. Chilkat2 PHP

<?php

use Chilkat2\SFtp;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$sftp = new SFtp();

// Connect to the SSH server.
$hostname = 'sftp.example.com';
$port = 22;
try {
    $sftp->Connect($hostname, $port);

    // Authenticate with the SSH server.  Chilkat SFTP supports
    // both password-based authenication as well as public-key
    // authentication.  This example uses password authenication.
    $sftp->AuthenticatePw('myLogin', 'myPassword');

    // After authenticating, the SFTP subsystem must be initialized:
    $sftp->InitializeSftp();
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

// Check to see if a file exists

// The return value is one of the following values:
// -1: Unable to check. Examine the LastErrorText to determine the reason for failure.
// 0: File does not exist.
// 1: The regular file exists.
// 2: It exists, but it is a directory.
// 3: It exists, but it is a symlink (only possible if followLinks is false)
// 4: It exists, but it is a special filesystem entry type.
// 5: It exists, but it is an unkown filesystem entry type.
// 6: It exists, but it is an socket filesystem entry type.
// 7: It exists, but it is an char device entry type.
// 8: It exists, but it is an block device entry type.
// 9: It exists, but it is an FIFO entry type.

$followLinks = true;
$status = $sftp->FileExists('someDir/someFile.txt', $followLinks);

    echo $sftp->LastErrorText, "\n";
