## Expect Usage Examples

Example #1 Expect Usage Example

This example connects to the remote host via SSH, and prints the remote uptime.

`<?php
ini_set("expect.loguser", "Off");
$stream = fopen("expect://ssh root@remotehost uptime", "r");
$cases = array (
array (0 => "password:", 1 => PASSWORD)
);
switch (expect_expectl ($stream, $cases)) {
case PASSWORD:
fwrite ($stream, "password\n");
break;
default:
die ("Error was occurred while connecting to the remote host!\n");
}
while ($line = fgets($stream)) {
print $line;
}
fclose ($stream);
?>`

The following example connects to the remote host, determines whether installed OS is for 32 or 64 bit, then runs update for specific package.

Example #2 Another Expect Usage Example

`<?php
ini_set("expect.timeout", -1);
ini_set("expect.loguser", "Off");
$stream = expect_popen("ssh root@remotehost");
while (true) {
switch (expect_expectl ($stream, array (
array ("password:", PASSWORD), // SSH is asking for password
array ("yes/no)?", YESNO), // SSH is asking whether to store the host entry
array ("~$ ", SHELL, EXP_EXACT), // We've got the shell!
))) {
case PASSWORD:
fwrite ($stream, "secret\n");
break;
case YESNO:
fwrite ($stream, "yes\n");
break;
case SHELL:
fwrite ($stream, "uname -a\n");
while (true) {
switch (expect_expectl ($stream, array (
array ("~$ ", SHELL, EXP_EXACT), // We've got the shell!
array ("^Linux.*$", UNAME, EXP_REGEXP), // uname -a output
), $match)) {
case UNAME:
$uname .= $match[0];
break;
case SHELL:
// Run update:
if (strstr ($uname, "x86_64")) {
fwrite ($stream, "rpm -Uhv http://mirrorsite/somepath/some_64bit.rpm\n");
} else {
fwrite ($stream, "rpm -Uhv http://mirrorsite/somepath/some_32bit.rpm\n");
}
fwrite ($stream, "exit\n");
break 2;
case EXP_TIMEOUT:
case EXP_EOF:
break 2;
default:
die ("Error has occurred!\n");
}
}
break 2;
case EXP_TIMEOUT:
case EXP_EOF:
break 2;
default:
die ("Error has occurred!\n");
}
}
fclose ($stream);
?>`
