take numbers into separate variables

Question

I have a little php script to telnet an adsl modem, i send a consult and the modem respond is something like this:

wan adsl chandata far
near-end interleaved channel bit rate: 4864 kbps
near-end fast channel bit rate: 0 kbps
far-end interleaved channel bit rate: 957 kbps
far-end fast channel bit rate: 0 kbps

so, i want to take only the "4864" - "957" values and store them into separate variables, can anyone help me with this?

Thanks in advance.

So you basically need to separate the numbers from the text that is returned in the response? Sounds like some Regular Expressions could come in handy for this. Depending on PHP's RegEx engine, it might look something like this:

regexobject = /[0-9]*/

[0-9] means a character that is zero through nine
* the star after means a character zero to 9 that occurs zero or more times
the / / may not be the correct way to do it for PHP, but I would look up how to do it for PHP. Search for "PHP regular expression". You'll probably want to use a function that returns the matched string, then convert the string to an integer, if you need to use it as an integer.
