php - Foreach comes back as Array Array -


not sure i'm doing wrong one, when attempt foreach loop variable, comes array array.

php code:

  <?php foreach ($thing $t) : ?>     <?php $thisstuff = $t[stuff];  ?>     <?php echo $thisstuff; ?>   <?php endforeach; ?>

output: array array

could possibly there array within $thisstuff? if loop through data?

if have multidimensional array you'll need use recursive function.

an example might this

function unfoldarray($array,$output = array()) {     if(is_object($array)) {         $array = (array)$array;     }     foreach($array $key => $value) {         if(is_array($value) || is_object($value)) {             //$output[] = $key;             $output = unfoldarray($value,$output);         } else {             $output[] = $value;         }     }     return $output; }

the above function, given array like

$array = array(     "one",     "two",     "three" => array("a","b","c"),     "four" => array("x","y","z"),     "five",     "six" => array(         "sub_one",         "sub_two",         "sub_three" => array("sub_a","sub_b","sub_c")     ),     "seven" ); $output = unfoldarray($array);

would return flat array this

   // $output     [         "one",         "two",         "a",         "b",         "c",         "x",         "y",         "z",         "five",         "sub_one",         "sub_two",         "sub_a",         "sub_b",         "sub_c",         "seven"     ]

you may notice values "three" , "six" omitted result array because key, if wan include them uncomment line //$output[] = $key; in function.

once have array may loop foreach. might not need, should give direction follow.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
