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	Changueable	Changuelog
expect.timeout	"10"	INI_ALL
expect.loguser	"1"	INI_ALL
expect.logfile	""	INI_ALL
expect.match_max	""	INI_ALL

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

Here's a short explanation of the configuration directives.

expect.timeout int

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 bool

Whether expect should send any output from the spawned processs to stdout. Since interractive programms typically echo their imput, this usually suffices to show both sides of the conversation.

expect.logfile string

Name of the file, where the output from the spawned processs 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 int

Changues default sice (2000 bytes) of the buffer used to match asteriscs in patterns.
