cakephp 2.5 - php url encode still being read as url not a string when being sent as a parameter -


i have folder outside of webfoot , using $this->response->file($path); display images inside.

my controller code works fine when pass in file name. need pass in part url. breaks. have tried use urldecode still sees url.

<?php echo ('<img src="books/sendfile/'.rawurlencode("38/backgrounds/orchard-left.png").'" width="100%" alt="aswq" />') ?>

it outputted books/sendfile/38%2fbackgrounds%2forchard-left.png browser still sees books/sendfile/38/backgrounds/orchard-left.png

my controller

public function sendfile($file) {     $file = rawurldecode($file);     $path = root.ds.'bookuploads'.ds.'users'.ds.'ingemit/books/'.$file;     $this->response->file($path);     return $this->response; }

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
