i have following array var useridarray=["1", "3", "6", "39", "62", "139"]; i want remove array value using value i have tried following method function deletemember(id) { alert(id+"="+useridarray.indexof(id)); useridarray.splice(useridarray.indexof(id),1); } but remove last value. also noticed useridarray.indexof(id) return -1 if pass value useridarray.indexof("6") delete particular position can 1 me how remove particular value ? i think got problem id putting deletemember functions isn't string. this solve problem: var useridarray=["1", "3", "6", "39", "62", "139"]; function deletemember(id) { removeid = string(id) removeindex = useridarray.indexof(removeid) if(removeindex != -1) useridarray.splice(removeindex,1); } deletemember(3) ...

i have common setup, have table of tags , record pairs. querying slow adding index column of tag querying helps speed up. tag | site 123 | 456 789 | 101 my question whether beneficial add index on both these columns 1 index. never selected site, there benefit doing this? cannot guarantee each pairing unique without making changes if did performance? a typical query might this: select site , tag sitetags tag ='123' or tag = '789' if search tag need index tag column. adding column index when not used, introduce unneeded overhead when insert or update record , consume more storages. but composite index ( tag , site ) may give additional optimization mysql need read index satify query ( explain marks optimization using index ). if operation read rather write, using composite index may not bad idea. it better if tag column has high cardinality, meaning there high chance values different between each rows. but suggest consult explain...

i've 2 arrays bellow: array (size=2) 827 => int 3 868 => int 3 array (size=4) 827 => int 2 868 => int 2 829 => int 1 541 => int 1 i want combine 2 arrays , add values when keys matches. resulting array needs be: array (size=4) 827 => int 5 868 => int 5 829 => int 1 541 => int 1 tried different array manipulation function none of them worked. appreciated. you can following: using + on arrays, creating new array, have key/values of both, duplicates not overriden second one. after can loop again on second array , and add values (but if value not present in $a1). if not present in $a1, value in merged array $a2. $a1 = array(827 => 3, 868 => 3); $a2 = array(827 => 2, 868 => 2, 829 => 1, 541 => 1); $merged = $a1+$a2; foreach($a2 $key => $value){ if(!empty($a1[$key])){ $merged[$key] = $merged[$key] + $value; } }

in app, have notification button fires off short network request in background using intentservice. not make sense show gui here, why use service instead of activity. see code below. // build intent used start notifactionservice intent buttonactionintent = new intent(this, notifactionservice.class); buttonactionintent.setaction(notifactionservice.action_send_confirm); buttonactionintent.putextra(notifactionservice.extra_confirm_id, confirmid); buttonactionintent.putextra(notifactionservice.extra_notif_id, notifid); // build pendingintent used trigger action pendingintent pendingintentconfirm = pendingintent.getservice(this, 0, buttonactionintent, pendingintent.flag_update_current); this works reliably new background restrictions in android 8.0 made me want move jobintentservice instead. updating service code seems straight forward don't know how launch via pendingintent, notification actions require. how accomplish this? would better move normal service , use pendingin...

i'm following symfony3 intro. i ran php bin/console generate:controller , followed prompts, choosing yaml routing because don't comments code. it generated following: number: path: /lucky/number defaults: { _controller: appbundle:lucky:number } and placed src/appbundle/resources/config/routing.yml this doesn't work. however, copying contents app/config/routing.yml does. it seems i'm missing additional config doesn't mention in guide because expects use annotations routes. doesn't mention in docs here under "using other formats" section. is copying generated route other file right thing do? there alternative step tells find other yaml based routes? in app/config/routing.yml can do: app: resource: '@appbundle/resources/config/routing.yml' and write inside of appbundle/resources/config/routing.yml work
