Runtime Configuration

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.

Expect Configure Options

Name	Default	Changeable	Changelog
expect.timeout	"10"	PHP_INI_ALL
expect.loguser	"1"	PHP_INI_ALL
expect.logfile	""	PHP_INI_ALL
expect.match_max	""	PHP_INI_ALL

For further details and definitions of the PHP_INI_* modes, see the Where a configuration setting may be set.

Here's a short explanation of the configuration directives.

expect.timeout integer

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.

expect.loguser boolean

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.

expect.logfile string

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.

expect.match_max integer

Changes default size (2000 bytes) of the buffer used to match asterisks in patterns.
