In PHP, ftp_get_option() helps with runtime and application data. Reads an option from an FTP connection, such as its timeout setting.
What Is ftp_get_option() in PHP?
The function or method has a specific purpose: Reads an option from an FTP connection, such as its timeout setting. The following examples show the main call, one additional situation, and an application-style use.
Syntax:
<?php
ftp_get_option(FTP\Connection $ftp, int $option) : int|bool
Parameters and Return Value
$ftp(FTP\Connection) — argument used by this API to perform its operation; required.$option(int) — argument used by this API to perform its operation; required.
Example 1: Basic Usage
Reads an option from an FTP connection, such as its timeout setting.
<?php
$ftpConnection = ftp_connect("ftp.example.test");
if ($ftpConnection === false) { throw new RuntimeException("Connection failed"); }
var_dump(ftp_get_option($ftpConnection, FTP_TIMEOUT_SEC));
ftp_close($ftpConnection);
This example demonstrates the central operation. The final output depends on the supplied input and, where relevant, the runtime or connected service.
Example 2: Handling a Different Case
<?php
// Optional parameters and failures matter; check return values before continuing.
$ftpConnection = ftp_connect("ftp.example.test");
if ($ftpConnection === false) { throw new RuntimeException("Connection failed"); }
var_dump(ftp_get_option($ftpConnection, FTP_TIMEOUT_SEC));
ftp_close($ftpConnection);
The second example focuses on a different input or failure condition, so the behavior can be distinguished from the basic case.
Practical Example
<?php
// In an application, place the call inside a checked workflow.
$ftpConnection = ftp_connect("ftp.example.test");
if ($ftpConnection === false) { throw new RuntimeException("Connection failed"); }
var_dump(ftp_get_option($ftpConnection, FTP_TIMEOUT_SEC));
ftp_close($ftpConnection);
The practical example demonstrates how the same subject fits into a larger application. Use your own file paths, endpoints and validated inputs rather than copying sample settings directly.
Important Behavior and Edge Cases
- Reads an option from an FTP connection, such as its timeout setting.
- Check the return value and exceptions for failure before using the result. If an extension or external system is required, the example only works when that dependency is available. Network outcomes are not deterministic and responses should not be assumed to be successful.
- Use the documented return type and handle false, null and exceptions according to the specific call.
Comparison With Related Functions
| Approach | Difference |
|---|---|
| ftp_get_option | Reads an option from an FTP connection, such as its timeout setting. |
| ftp_get | Downloads a complete remote file using a connected FTP session. |
Common Beginner Mistakes
| Mistake | Correct Approach |
|---|---|
| Assuming FTP is encrypted | Use an appropriate protected transport; plain FTP sends credentials without modern channel protection. |
| Downloading before successful authentication | Check the connection and login result before transfer. |
| Ignoring partial or failed downloads | Check the transfer status and validate the completed file. |
Key Takeaways
- Reads an option from an FTP connection, such as its timeout setting.
- Check the return value and exceptions for failure before using the result. If an extension or external system is required, the example only works when that dependency is available. Network outcomes are not deterministic and responses should not be assumed to be successful.
- Use the documented return type and handle false, null and exceptions according to the specific call.
Reads an option from an FTP connection, such as its timeout setting. Use this approach when its capabilities and constraints match the application. Handle invalid data, failure conditions and resource cleanup explicitly.
