This extension allows to interact with processes through PTY. You may consider using the expect:// wrapper with the filesystem functions which provide a simpler and more intuitive interface.
This module uses the functions of the expect library. You need libexpect version >= 5.43.0.
Denne PECL udvidelse medfølger ikke i PHP. Uddybende information så som nye udgivelser, downloads, kildekoder, vedligeholder information samt en CHANGELOG, kan findes her: http://pecl.php.net/package/expect.
I PHP 4 er denne PECL udvidelses
kildekode kan blive fundet i ext/ biblioteket inde i
PHP kildekoden eller ved PECL linket ovenover.
In order to use these functions you must compile PHP with expect support
by using the --with-expect[=DIR]
configure option.
Windows users will enable php_expect.dll inside of php.ini in order to use these functions. I PHP 4 befinder denne DLL sig i extensions/ biblioteket inde i PHP Windows binær download. Du kan hente denne PECL udvidelse DLL fra PHP Downloads siden eller på http://snaps.php.net/.
Virkemåden af disse funktioner er berørt af indstillinger i php.ini.
In order to configure expect extension, there are configuration options in the configuration file php.ini.
Tabel 1. Expect Configure parametre
Navn | Standard | Foranderlig | Changelog |
---|---|---|---|
expect.timeout | "10" | PHP_INI_ALL | |
expect.loguser | "1" | PHP_INI_ALL | |
expect.logfile | "" | PHP_INI_ALL |
Her er en kort forklaring på konfigurations-direktiverne.
expect.timeout
integerThe timeout period for waiting for the data, when using the expect_expectl() function.
A value of "-1" disables a timeout from occurring.
Bemærk: A value of "0" causes the expect_expectl() function to return immediately.
expect.loguser
booleanWhether 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
stringName of the file, where the output from the spawned process will be written. If this file doesn't exist, it will be created.
Bemærk: If this configuration is not empty, the output is written regardless of the value of expect.loguser.
expect_popen() returns an open PTY stream used by expect_expectl().
Konstanterne nedenunder er defineret af denne udvidelse, og vil kun være tilgængelige når denne udvidelse enten er blevet kompileret ind i PHP eller dynamisk indsat under 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() upon timeout of seconds, specified in value of expect.timeout
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.
