PHP Remove duplicates from multidimensional array based on key -

-

i have multidimensional array ($array) in entries like:

{ ["upload/example.gif"]=> array(5) {       ["title"]=> string(12) "this me"       ["excerpt"]=> string(24) "this photo of tree"       ["img"]=> string(42) "upload/example.gif"      ["link"]=> string(23) "http://www.google.co.uk"       ["source"]=> string(6) "custom"     } }

i need able remove duplicate values in $array based on key. if array was:

$array = array( ["upload/example.gif"] => etc....                 ["upload/tree.gif"] => etc....                 ["upload/example.gif"] => etc....)

i able remove 1 of ["upload/example.gif"] => etc.... arrays.

i have tried:

$array = array_map('unserialize', array_unique(array_map('serialize', $array)));

but didn't work.

thanks in advance.

netcoder answered question properly, wanted show in answer box (instead of comment).

you can't have duplicate keys in associative array (or array). nature of being array can gauranteed have unique keys.

btw if find duplicate data in different keys can remove redundant key unsetting it.

unset($array['delete_me']);

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
