sorry if title confusing, couldn't find correct words formulate correctly. a little bit of context: i'm trying data 2 classes , echo them 1 line. here's code: foreach ($site->find('.version a') $source) { foreach ($site->find('.version_numb') $pwgetframe) { $pwframe = $pwgetframe->innertext; $geturl = $source->href; $pwversion = $source->plaintext; echo '<div class="linkframe"><a href="'.$geturl.'">'.$pwversion.'</a><div>'.$pwframe.'</p></div>'; } } this code made each linkframe inside previous linkframe making inception. what can make work correctly? although it's not clear understand you're after question, believe you're looking following: $source = $site->find('.version a'); $pwgetframe = $site->find('.version_numb'); ($i=0; $i < sizeof($source); $i++) { $pwframe = $pwgetframe[$i]

i fresher. can validate data in input form id=entered data. if data wrong should change color of form. out j query, java script, ajax. yes, can use html5 validate data, however recommended use example jquery validation since not browsers support html5 validation. for example use simplified url-validator, <input type="url" name="website" required pattern="https?://.+"> you use html5, jquery, java script etc on client side when want validate something. php on other hand use verify form data on server side, is, when data has been submitted form's action page.

how hello “newline” , world in powershell using regex? hello world i have hello world text file. i'm using powershell. this should work $match = get-content -path <path_to_file> | out-string | select-string "hello`r`nworld" if ( $match ) { write-host $match.matches[0].groups[0].value } we load file get-content flatten array single string, in case piping out-string . finally, regex applied embedded crlf. if have powershell 3, believe can use get-content -raw (which returns single string) , pipe straight select-string . my test file: line1 hello world line4 output: hello world

i have gcm sample android gradle project. worked well, when add 2 flavors push notification stopped work. compilation manifest (it's taken app\build\intermediates\manifests\ex\debug ) file below: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.flavor.app" <uses-permission android:name="com.flavor.app.permission.c2d_message" /> <permission android:name="com.flavor.app.permission.c2d_message" android:protectionlevel="signature" /> <receiver android:name="com.google.android.gcm.gcmbroadcastreceiver" android:permission="com.google.android.c2dm.permission.send" > <intent-filter> <action android:name="com.google.android.c2dm.intent.receive" /> <action android:name="com.google.android.c2dm.intent.registration" />

it seems can not find elegant solution synchronization of code below. remember once did similar thing mind blank. i need protect no 2 threads read socket, 1 thread waits on beginread. when use mutex in way, syncronizationerror. class program { tcpclient client = new tcpclient(); public readonly object loker = new object(); public void beginread() { if (!mutex.tryenter(loker)) { return; } client.getstream().beginread(..., read_callback); } private void read_callback(iasyncresult ar) { client.getstream().endread(ar); mutex.exit(loker); beginread(); } static void main(string[] args) { beginread(); } } what need here synchronization method designed asynchronous, rather synchronous, critical sections. want able run code asynchronously after code able take out lock rather making asynchronous method use synchronous locking mechanisms. synchronous mech

it takes approx. 190s complete loop below on laptop intel i5, 8gb, windows 7. count = 0 l in xrange(num_room): k in xrange(num_slot): m in xrange(num_activity): count = count+1 dk, [om, ol, ok] in xdict.iteritems(): if dk == (m,l,k): # i did trace , found out total loop 13960 x 19040 ~ 2bils. len(self.xdict): 13960 count: 19040 xdict looks (an example): xdict = {(19, 4, 118): [19, 4, 4], (4, 12, 25): [4, 12, 7], (15, 19, 121): [15, 19, 21], (23, 5, 219): [23, 5, 9], (13, 5, 19): [13, 5, 1]} i trying value of key in dictionary. there anyway improve performance? sorry, think know happen. count = 0 l in xrange(num_room): k in xrange(num_slot): m in xrange(num_activity): count = count+1 val = xdict.get((m,l,k)) if val != none: [om, ol, ok] = val # now takes 1s. don't loop on i

essentially happens when run code "print block[j]" section of program gets run, test code have afterwards i.e. print block[k] , print "testing code" not reached. i've been staring @ program last half hour , can't figure out why program can reach beyond 2nd nested loop not third. def swapii(str): new_str = "" letter in str: if letter.isupper(): new_str = new_str + letter.lower() else: new_str = new_str + letter.upper() new_list = new_str.split(' ') in new_list: block = i.split() j in range(len(block)): print block[j] k in range(j+1, len(block)): print block[k] if block[j].isdigit() , block[k].isdigit(): lala = block[j] block[j] = block[k] block[k] = lala print "testing code" = ''.join(block) return ' '.join(new_list) # keep function call here # see

i new codeigniter. want create new controller checks other controller , methods if user logged in already. using session way. stated here codeigniter - how check session used @ every methods , here . i need create my_controller.php inside application/core folder. <?php class my_controller extends ci_controller { function __construct() { parent::__construct(); } } ?> public_controller.php <?php class public_controller extends my_controller { function __construct() { parent::__construct(); // session stuff here :) } } admin_controller.php <?php class admin_controller extends my_controller { function __construct() { parent::__construct(); // session stuff here :) } } what should add inside 2 new controller can use in controller base.php? or how can implement session checking? sorry, hard me explain. make ur my_controller this: <?php class my_controller extends ci_con
