The ftp_size() function is an inbuilt function in PHP which is used to get the size of a given file on FTP server.
Syntax:
ftp_size( $ftp_connection, $file_name );
Parameter: This function accepts two parameters as mentioned above and described below:
- $ftp_connection: It is required parameter. It specifies the already existing FTP connection to use where the file exists.
- $file_name: It is required parameter. It specifies the file or file path on remote server i.e. FTP server.
Return Value: It returns the size of file on success or -1 on error.
Note:
- All ftp server doesn’t support this function.
- This function is available on PHP 4.0.0 and newer version.
- The following examples cannot be run on online IDE. So try to run in some PHP hosting server or localhost with proper ftp server name.
Below examples illustrate the ftp_size() function in PHP:
Example 1:
php
<?php // Connect to FTP server // Use a correct ftp server $ftp_server = "localhost" ;
// Use correct ftp username $ftp_username = "user" ;
// Use correct ftp password corresponding // to the ftp username $ftp_userpass = "user" ;
// File name or path to upload to ftp server $file = "shiva.jpg" ;
// Establishing ftp connection $ftp_connection = ftp_connect( $ftp_server )
or die ( "Could not connect to $ftp_server" );
if ( $ftp_connection ) {
echo "successfully connected to the ftp server!" ;
// Logging in to established connection with
// ftp username password
$login = ftp_login( $ftp_connection , $ftp_username , $ftp_userpass );
if ( $login ) {
// Checking whether logged in successfully or not
echo "<br>logged in successfully!" ;
// Size of the file using ftp_size() function.
$file_size = ftp_size( $ftp_connection , $file );
if ( $file_size != -1) {
echo "<br>$file is $file_size bytes." ;
}
else {
echo "<br>Error getting file size." ;
}
}
else {
echo "<br>login failed!" ;
}
// echo ftp_get_option($ftp_connection, 1);
// Closing connection
if (ftp_close( $ftp_connection )) {
echo "<br>Connection closed Successfully!" ;
}
} ?> |
Output:
Example 2: Connect to ftp server using port number 21.
php
<?php // Connect to FTP server // Use a correct ftp server $ftp_server = "localhost" ;
// Use correct ftp username $ftp_username = "user" ;
// Use correct ftp password corresponding // to the ftp username $ftp_userpass = "user" ;
// File name or path to upload to ftp server $file = "shiva.jpg" ;
// Establishing ftp connection $ftp_connection = ftp_connect( $ftp_server , 21)
or die ( "Could not connect to $ftp_server" );
if ( $ftp_connection ) {
echo "successfully connected to the ftp server!" ;
// Logging in to established connection with
// ftp username password
$login = ftp_login( $ftp_connection , $ftp_username , $ftp_userpass );
if ( $login ) {
// Checking whether logged in successfully or not
echo "<br>logged in successfully!" ;
// Size of the file using ftp_size() function.
$file_size = ftp_size( $ftp_connection , $file );
if ( $file_size != -1) {
echo "<br>$file is $file_size bytes." ;
}
else {
echo "<br>Error getting file size." ;
}
}
else {
echo "<br>login failed!" ;
}
// echo ftp_get_option($ftp_connection, 1);
// Closing connection
if (ftp_close( $ftp_connection )) {
echo "<br>Connection closed Successfully!" ;
}
} ?> |
