This module uses the functions of the expect library. You need libexpect version >= 5.43.0.
This PECL extension is not bundled with PHP. Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: http://pecl.php.net/package/expect.
In PHP 4 this PECL extensions
source can be found in the ext/ directory within the
PHP source or at the PECL link above.
In order to use these functions you must compile PHP with expect support
by using the
Windows users will enable php_expect.dll inside of php.ini in order to use these functions. In PHP 4 this DLL resides in the extensions/ directory within the PHP Windows binaries download. You may download this PECL extension DLL from the PHP Downloads page or at http://snaps.php.net/.
The behaviour of these functions is affected by settings in php.ini.
In order to configure expect extension, there are configuration options in the configuration file php.ini.
Table 1. Expect Configure Options
Here's a short explanation of the configuration directives.
The timeout period for waiting for the data, when using the expect_expectl() function.
A value of "-1" disables a timeout from occurring.
Note: A value of "0" causes the expect_expectl() function to return immediately.
Whether expect should send any output from the spawned process to stdout. Since interactive programs typically echo their input, this usually suffices to show both sides of the conversation.
Name of the file, where the output from the spawned process will be written. If this file doesn't exist, it will be created.
Note: If this configuration is not empty, the output is written regardless of the value of expect.loguser.
This extension has no resource types defined.
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
Indicates that the pattern is a glob-style string pattern.
Indicates that the pattern is an exact string.
Indicates that the pattern is a regexp-style string pattern.
Value, returned by expect_expectl(), when EOF is reached.
Value, returned by expect_expectl() if no pattern have been matched.
This example connects to the remote host via SSH, and prints the remote uptime.
