expect_expectl — Waits until the output from a process matches one of the patterns, a specified time period has passed, or an EOF is seen
Waits until the output from a process matches one of the patterns, a specified time period has passed, or an EOF is seen.
If match is provided, then it is filled with the result of search. The matched string can be found in match[0]. The match substrings (according to the parentheses) in the original pattern can be found in match[1], match[2], and so on, up to match[9] (the limitation of libexpect).
An Expect stream, previously opened with expect_popen().
An array of expect cases. Each expect case is an indexed array, as described in the following table:
| Index Key | Value Type | Description | Is Mandatory | Default Value |
|---|---|---|---|---|
| 0 | string | pattern, that will be matched against the output from the stream | yes | |
| 1 | mixed | value, that will be returned by this function, if the pattern matches | yes | |
| 2 | integer | pattern type, one of: EXP_GLOB, EXP_EXACT or EXP_REGEXP | no | EXP_GLOB |
Returns value associated with the pattern that was matched.
On failure this function returns: EXP_EOF, EXP_TIMEOUT or EXP_FULLBUFFER
| Version | Beschreibung |
|---|---|
| 0.2.1 | Prior to version 0.2.1, in match parameter a match string was returned, not an array of match substrings. |
Beispiel #1 expect_expectl() example
<?php
// Copies file from remote host:
ini_set ("expect.timeout", 30);
$stream = fopen ("expect://scp user@remotehost:/var/log/messages /home/user/messages.txt", "r");
$cases = array (
array (0 => "password:", 1 => PASSWORD),
array (0 => "yes/no)?", 1 => YESNO)
);
while (true) {
switch (expect_expectl ($stream, $cases))
{
case PASSWORD:
fwrite ($stream, "password\n");
break;
case YESNO:
fwrite ($stream, "yes\n");
break;
case EXP_TIMEOUT:
case EXP_EOF:
break 2;
default:
die ("Error has occurred!\n");
}
}
fclose ($stream);
?>
