Hi,
Can someone help me convert this PERl to PHP?

Perl: (replace START and END to print everything between the two)
perl -0777 -ne 'print "$1\n" while /START(.*?)END/gs'

Php:
???

Ok, so I have this, but it doesn't seem to work -- it only prints out the first 3 parts of the array????


// Example: printbetween("<title>", "<\/title>", $html_content);
function printbetween($start,$end,$data) {
    // preg_match("/$start(.*)$end/s",$data,$match);
    preg_match("/$start(.*?)$end/i",$data,$match);
    return $match;
}

    $TT = printbetween("<TT>", "<\/TT>", $res);
   foreach ($TT as $v) {
        echo "Data:: " .htmlspecialchars($v) ."\n<br>";
    }      


And this returns:
Data:: <TT><SPAN CLASS="contentbold">%CDP-3-PKTRECVFAIL:</SPAN></TT>
Data:: <SPAN CLASS="contentbold">%CDP-3-PKTRECVFAIL:</SPAN>
Data::

But it SHOULD be returning:

<TT><SPAN CLASS="contentbold">%CDP-3-PKTRECVFAIL:</SPAN></TT>
<TT> Failed to receive packet - [chars].</TT>

For clarification, here's the page: I need to extract the following:

Error Message: %CDP-3-PKTRECVFAIL
Short Desc: Failed to receive packet - [chars].
Long Desc: Failed to receive a packet because of the reason shown in the error message.
Recommended Action: No action is required. Introduced Cisco MDS SAN-OS Release 1.2(2a).
Related documents: - No specific documents apply to this error message
Note that sometimes more than one result may be returned for the search, for example: if I just search on "CDP-", the page would return about 55 entries.

And here's the relevant html:

Try changing this line
  preg_match("/$start(.*?)$end/i",$data,$match);
into
  preg_match_all("/$start(.*?)$end/i",$data,$match);

Then to get the array you want:
$final_match = array();
foreach($matches as $match) {
    $final_match[] = $match[0];
}
print_r($final_match);

That yeilds the same results...

function printbetween($start,$end,$data) {
    // preg_match("/$start(.*)$end/",$data,$match);
    preg_match_all("/$start(.*?)$end/i",$data,$match);
    return $match;
}        


   $TT = printbetween("<TT>", "<\/TT>", $res);
    $final_match = array();
    foreach($TT as $match) {
            $final_match[] = $match[0];
    }
    print_r($final_match);

Yeilds:
Array ( [0] => %CDP-3-PKTRECVFAIL: [1] => %CDP-3-PKTRECVFAIL: )

Can you add this line:
print_r($TT);

between these lines:
   $TT = printbetween("<TT>", "<\/TT>", $res);
    $final_match = array();

and show me the result?

k, here's what I did (removed the function "printbetween" in case it was causing the problem):

    $TT = preg_match_all("/<TT>(.*?)<\/TT>/i",$res,$match);
    echo "PRINT_R:<br>";
    print_r($match);
    echo "<BR>END PRINT_R:<br>";
    $final_match = array();
    echo "Foreach Loop: <br>";
    foreach($match as $matches) {
        $final_match[] = $matches[0];
    }
    print_r($final_match);


Output:
Array ( [0] => Array ( [0] => %CDP-3-PKTRECVFAIL: [1] => Failed to receive packet - [chars]. ) [1] => Array ( [0] => %CDP-3-PKTRECVFAIL: [1] => Failed to receive packet - [chars]. ) )
END PRINT_R:
Foreach Loop:
Array ( [0] => %CDP-3-PKTRECVFAIL: [1] => %CDP-3-PKTRECVFAIL: )

Eureka, I think I have it!

    $TT = preg_match_all("/<TT>(.*?)<\/TT>/i",$res,$match);
    echo "<br>";
    echo "Match: " .$match[0][0];
    echo "<br>";
    echo "Match2: " . $match[0][1];
    echo "<br>";
    echo "<br>";

Yeilds:

Match: %CDP-3-PKTRECVFAIL:
Match2: Failed to receive packet - [chars].

Hrm...oddly enough, if I take the following:

    print "<b><font color=\"green\">END REPLY ARRAY</b></font><br>\n";
    $TT = preg_match_all("/<TT>(.*?)<\/TT>/i",$res,$match);
    echo "PRINT_R:<br>";
    print_r($match);
    echo "<BR>END PRINT_R:<br>";
    $final_match = array();
    echo "Foreach Loop: <br>";
    foreach($match as $matches) {
        $final_match[] = $matches[0];      
    }                                          
    print_r($final_match);        


Then it prints everything between <TT> and </TT>
Output:
PRINT_R:
Array ( [0] => Array ( [0] => %CDP-3-PKTRECVFAIL: [1] => Failed to receive packet - [chars]. ) [1] => Array ( [0] => %CDP-3-PKTRECVFAIL: [1] => Failed to receive packet - [chars]. ) )
END PRINT_R:
Foreach Loop:
Array ( [0] => %CDP-3-PKTRECVFAIL: [1] => %CDP-3-PKTRECVFAIL: )



But, if I widen it to print everything between <FORM> and </FORM> it doesn't work, why is that?
Output:
PRINT_R:
Array ( [0] => Array ( ) [1] => Array ( ) )
END PRINT_R:
Foreach Loop:
Array ( [0] => [1] => )

By default the period (.) does not match new lines. You can modify this behaviour with the s (PCRE_DOTALL) modifier:

$TT = preg_match_all("/<FORM>(.*?)<\/FORM>/is", $res, $match);
