Regex Help

[mrxxlphp]

Hi guys, I have looked at PHP's extensive REGEX functions but I am stuck trying to find the best way to break down a large string into a predictable array regardless of the length of each part of the string.

I need to parse the following with PHP:

ath0      IEEE 802.11g  ESSID:"Testing"  

          Mode:Managed  Frequency:2.45 GHz  Access Point: 00:10:2Z:CF:21:09   

          Bit Rate:27 Mb/s   Tx-Power=23 dBm   Sensitivity=1/3  

          Retry:off   RTS thr=768 B   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=18/94  Signal level=-77 dBm  Noise level=-95 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

What I need is to be able to accurately get the signal level (-77) the noise level (-95) and Access Point (00:10:2Z:CF:21:09).

If anyone can help me, I would be very appreciative.

Thanks, Stuart

If it's always in that sequence in the sample text:

<?php
$text = <<<EOD
ath0      IEEE 802.11g  ESSID:"Testing"
          Mode:Managed  Frequency:2.45 GHz  Access Point: 00:10:2Z:CF:21:09
          Bit Rate:27 Mb/s   Tx-Power=23 dBm   Sensitivity=1/3
          Retry:off   RTS thr=768 B   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=18/94  Signal level=-77 dBm  Noise level=-95 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0
EOD;

$ap = '(?<=Access Point: )(\S+)';
$sl = '(?<=Signal level=)(\S+)';
$nl = '(?<=Noise level=)(\S+)';
$regexp = "/$ap.*$sl.*$nl/s";
preg_match($regexp, $text, $matches);
printf("<pre>%s</pre>", print_r($matches,1));

Output:

Array
(
    [0] => 00:10:2Z:CF:21:09
          Bit Rate:27 Mb/s   Tx-Power=23 dBm   Sensitivity=1/3
          Retry:off   RTS thr=768 B   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=18/94  Signal level=-77 dBm  Noise level=-95
    [1] => 00:10:2Z:CF:21:09
    [2] => -77
    [3] => -95
)
