the following code fail create zip file in php 5.6.12 , fail print out zip error message, instead displaying error / warning warning: ziparchive::getstatusstring(): invalid or uninitialized zip object in /tmp/x.php on line 9 but why? once worked in php 5.4. <?php // todo: check errors $temppath = tempnam('/tmp', 'ztmp'); $zip = new ziparchive(); $res = $zip->open($temppath, ziparchive::overwrite | ziparchive::create | ziparchive::excl); if ( $res !== true ) die($zip->getstatusstring()."\n"); it looks semantics have changed somewhat; unclear whether deliberate or bug. anyways, problem have empty file not valid zip being opened nonetheless , not initialized though requested file overwritten. so workaround or fix delete existing file , recreate it: <?php $temppath = tempnam('/tmp', 'ztmp'); // delete first @unlink($temppath); $zip = new ziparchive(); $res = $zip->open($temppath, ziparchive::ove...

this question has answer here: how subtract vector each row of matrix? [duplicate] 2 answers i'm trying substract 1 x m matrix n x m matrix. lets 1 x m matrix [1 2] and n x m matrix [3 4; 5 4; 1 6] and want result [2 2; 4 2; 0 4] i know how loop etc, i'm trying figure out is there math way of doing in single line? thanks. you can use repmat function extend 1xm matrix nxm , perform subtraction. >> m = [1 2]; >> n = [3 4; 5 4; 1 6]; >> n - repmat(m, length(n), 1) ans = 2 2 4 2 0 4 alternatively pointed out divakar can use >> bsxfun(@minus, n, m) ans = 2 2 4 2 0 4

first off, apologies long post. it's more simple looks ;-) i'm trying think conceptually simple, , believe i'm of way there, there's 1 last part can't implement without errors can't figure out how fix. i have 3 related tables. orders : each row order unique id, there never duplicates. +---------+---------+ | orderid | name | +---------+---------+ | 1 | order 1 | | 2 | order 2 | | 3 | order 3 | +---------+---------+ order details: relational table each row product line on order. +---------+-----------+ | orderid | productid | +---------+-----------+ | 1 | | | 2 | b | | 2 | c | | 3 | | | 3 | b | | 3 | b | +---------+-----------+ as can see orders have 1 product (1), have multiple products (2) , have duplicate products (3). products each row product unique id, there never duplicates. +-----------+-------------+ | productid | description ...
