Getting the last modified date of a file in C -


i want last modified date of file in c. sources found use along snippet:

char *get_last_modified(char *file) { struct tm *clock; struct stat attr; stat(file, &attr); clock = gmtime(&(attr.st_mtime)); return asctime(clock); }

but attr doesn't have field st_mtime, st_mtimespec. yet, when using eclipse tells me passing argument 1 of 'gmtime' incompatible pointer type on line clock = gmtime(&(attr.st_mtimespec));

what doing wrong?

ps: i'm developing on osx snow leopard, eclipse cdt , using gcc cross-platform compiler

on os x, st_mtimespec.tv_sec equivalent of st_mtime.

to make portable, do

#ifdef __apple__ #ifndef st_mtime #define st_mtime st_mtimespec.tv_sec #endif #endif

and use st_mtime.

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
