(PHP ActiveX) SFTP Get Size of File on ServerSee more SFTP ExamplesDemonstrates how to get the size of an existing file on the server.
<?php // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $sftp = new COM("Chilkat_9_5_0.SFtp"); // Set some timeouts, in milliseconds: $sftp->ConnectTimeoutMs = 5000; $sftp->IdleTimeoutMs = 10000; // Connect to the SSH server. // The standard SSH port = 22 // The hostname may be a hostname or IP address. $hostname = 'sftp.example.com'; $port = 22; $success = $sftp->Connect($hostname,$port); if ($success != 1) { print $sftp->LastErrorText . "\n"; exit; } // Authenticate with the SSH server. Chilkat SFTP supports // both password-based authenication as well as public-key // authentication. This example uses password authenication. $success = $sftp->AuthenticatePw('myLogin','myPassword'); if ($success != 1) { print $sftp->LastErrorText . "\n"; exit; } // After authenticating, the SFTP subsystem must be initialized: $success = $sftp->InitializeSftp(); if ($success != 1) { print $sftp->LastErrorText . "\n"; exit; } // Assuming we know the file size won't be too large, we get the size as a 32-bit integer. // For SFTP, the remote file path is always either a path relative to the HOME directory of the user account, or an absolute path on the server. $bFollowLinks = 1; $bIsHandle = 0; $fileSize = $sftp->GetFileSize32('someDir/someFile.dat',$bFollowLinks,$bIsHandle); if ($fileSize < 0) { print $sftp->LastErrorText . "\n"; exit; } print 'file size = ' . $fileSize . "\n"; // If the file size might be too large for a 32-bit signed integer, then get the size as a decimal string. // You can convert the string to a 64-bit integer in your programming language. $fileSizeStr = $sftp->getFileSizeStr('someDir/someFile.dat',$bFollowLinks,$bIsHandle); if ($sftp->LastMethodSuccess == 0) { print $sftp->LastErrorText . "\n"; exit; } print 'file size = ' . $fileSizeStr . "\n"; // You can alternatively get the size with an open file handle. $handle = $sftp->openFile('someDir/someFile.dat','readOnly','openExisting'); if ($sftp->LastMethodSuccess != 1) { print $sftp->LastErrorText . "\n"; exit; } // Get the size using the handle. $bIsHandle = 1; $fileSize = $sftp->GetFileSize32('someDir/someFile.dat',$bFollowLinks,$bIsHandle); if ($fileSize < 0) { print $sftp->LastErrorText . "\n"; exit; } print 'file size = ' . $fileSize . "\n"; // ----------------------------------------------------------------------------- // Don't forget to close the file handle. // Otherwise open handles will accumulate on the server until eventually a limit // is reached and the server will fail on a call to OpenFile. // ----------------------------------------------------------------------------- // Close the file. $success = $sftp->CloseHandle($handle); if ($success != 1) { print $sftp->LastErrorText . "\n"; exit; } ?> |
