As a freelance IT guy, I occasionally get cause to work on technologies I don’t usually mess around with. I last did any PHP work over 10 years ago so obviously I am rusty but a trusty google search provided me all the information I needed. Here are some of the useful functions / methods / tips i’ve recently used on projects.
Upload file using FTP
// FTP access parameters
$host = 'ftp.example.org';
$usr = 'example_user';
$pwd = 'example_password';
// file to move:
$local_file = './example.txt';
$ftp_path = '/data/example.txt';
// connect to FTP server (port 21)
$conn_id = ftp_connect($host, 21) or die ("Cannot connect to host");
// send access parameters
ftp_login($conn_id, $usr, $pwd) or die("Cannot login");
// turn on passive mode transfers (some servers need this)
// ftp_pasv ($conn_id, true);
// perform file upload
$upload = ftp_put($conn_id, $ftp_path, $local_file, FTP_ASCII);
// check upload status:
print (!$upload) ? 'Cannot upload' : 'Upload complete';
print "\n";
Create a unique filename
$ourUniqueFilename = uniqid() . '.txt'; // generate a unique filename with the txt extension
Exception handling
try
{
// do some stuff to throw an error
}
catch(Exception $e)//catch exception
{
echo 'Caught exception: ', $e->getMessage(), "\n";
}
try
{
// do some stuff to throw an error
{
// do some stuff to throw an error
}
catch(Exception $e)//catch exception
{
echo ‘Caught exception: ‘, $e->getMessage(), “\n”;
}
