Disable multiple statements in PHP PDO -

-
is there way disable multiple statement queries in pdo? method works drivers supported? alternatively, there known filter detect multiple statements in string? i know prepared statements can better prevent sql injection risks, there reasons why can't use them in case. you barking wrong tree. multiple statement not synonym sql injection. it's subset, small one, out of zilliards other possible ways exploit injection. therefore should protect injection, not multiple statement. this, query sent database api have 100% hardcoded in script. achieve that, substitute variables in query placeholders.

Robots.txt for application -

-
is possible application within website have own robots.txt file? for example, have site running under http://www.example.com , has robots.txt file. we have seperate site running application under domain: http://www.example.com/website-app is possible keep robots.txt file seperate application or need put stuff application main root robots.txt? the robots.txt file needs reside in /robots.txt , there no way tell crawler can found anywhere else (like favicons example). if can should add root robots.txt (or put application on subdomain instead can have own file). if want control specific pages individually can use <meta> -tags instead, described @ robotstxt.org . since needs put on every page have crawler visit (but not index) @ least 1 page, won't follow other pages (unless tell to). small application in subdirectory might ok solution.

fortran - store multi dimensional arrays to be operated on along all the dimensions -

foreword the fortran program i'm writing should deal 1d, 2d , 3d problems depending on ndims , can 1, 2 or 3 , read input file. in these cases quantity/ies of interest can stored in arrays (one named phi ) of rank dims ( allocatable(:) or allocatable(:,:) or allocatable(:,:,:) ), or in arrays of rank 3 ( allocatable(:,:,:) third dimension set equal 1 in 2d or both second , third dimensions equal 1 in 1d); both cases explained in this answer . first approach seems more elegant me, in following assume second one, simpler. these quantities have operated on several subroutines (e.g. mysub ) along ndims dimensions (along "pencils" should give graphic idea), should call like select case (ndims) ! 3d case case (3) j = ... k = ... call mysub(phi(:,j,k)) end end = ... k = ... call mysub(phi(i,:,k)) end end = ... j = ... call mysub(phi(i,j,:)) end end ! 2d case case (2) j = ... k = ... call ...
