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
Popis
mixed expect_expectl ( resource $expect, array $cases, array &$match )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).
