Perl Slurp Regex Capture -


using perl have "slurped" in large file contains text below , trying capture regex $1 matches within file given regex. regex 

=~ /((get|put|post|connect).*?(content-type: (image\/jpeg)))/sgm

currently text in bold being captured, however, last capture treating lines 

"get /~sgtatham/putty/latest/x86/pscp.exe http/1.1" "content-type: text/html; charset=iso-8859-1"

as part of last capture , should not b/c "text/html" not equal regex capture of (image\/jpeg). want able capture last capture without the

"get /~sgtatham/putty/latest/x86/pscp.exe http/1.1" "content-type: text/html; charset=iso-8859-1" being included.

appreciate help, thank you.

you can easy (?!pattern), it's negative look-ahead assertion. recap read article positive examples of positive , negative lookahead (ourcraft.wordpress.com)

regular expression

$text =~ / ( # start capture (?:get|put|post|connect) # start phrase (?: (?!get|put|post|connect) # make sure we'havent these phrase . # accept character )*? # number of times (not greedy) content-type:\simage\/jpeg # end phrase ) # end capture /msx; print $1;

all occurrences

while($text =~ m/regexp/msxg) { print $1; }

output

get /~sgtatham/putty/0.62/x86/pscp.exe http/1.1 host: the.earth.li user-agent: mozilla/5.0 (macintosh; intel mac os x 10.6; rv:13.0) gecko/20100101 firefox/13.0 accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 accept-language: en-us,en;q=0.5 content-length: 315392 keep-alive: timeout=15, max=99 connection: keep-alive content-type: image/jpeg

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
