PHP while loop for HTML Generation: Should I Check Array values at each While Loop Iteration or use Post-Loop String Pro
Date : March 29 2020, 07:55 AM
it should still fix some issue I'm working on a PHP-written html calendar that writes each day of the month inside a while loop. , Here's another solution: $day = 1;
$strings = array();
while($day < 31) {
if (array_key_exists($day, $array)) {
$strings[$day] = $array['$day'] . " spots available";
} else {
$strings[$day] = "No spots available for this date";
}
$day += 1;
}
foreach ($strings as $day => $string) {
echo '<td title="' . $string . '">' . $day . '</td>';
}

Triple nested loop (while loop insde of for loop inside of while loop)

Does that help If you want m1 to be the cumulative list of means, then the last line needs to be indented to be inside the final while block. while d <335:
d = d + 1
y = fpsd[d]
y1 = y1 + [y]
m = np.mean(y1)
m1 = m1 + [m]

My loop works like this: loop, script, loop. I want this: loop, loop, code. The ForgottenServer 0.3.6

hop of those help? Can you just move the "set storage" to a second loop after the first? That's the only way that you'll be able to send all of the messages before doing any of the set storage calls. for _, pid in ipairs(getPlayersOnline()) do
if getCreatureStorage(pid, tmp[i].storeDamage) > -1 then
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, getPlayerName(pid)..': '..getCreatureStorage(pid, 11005))
end
end
for _, pid in ipairs(getPlayersOnline()) do
doCreatureSetStorage(pid, tmp[i].storeDamage, -1)
end

hope this fix your issue I have several row in a table in db and every row related with three tables and every table has many rows. when i loop main table rows i also loop three tables rows now if one of tables has a content in row then i want to prevent showing entire sub that loop only which contain a value. , This method uses relationship count comparison. Controller public function classWiseResult(Request $request){
$students = Students::where('class',$request->class)
->withCount(['firstTerm as firstTermPromoted' => function($q) {
$q->where('number', '>', 32);
}])
->withCount('firstTerm as firstTermAllCount')
->withCount(['secondTerm as secondTermPromoted' => function($q) {
$q->where('number', '>', 32);
}])
->withCount('secondTerm as secondTermAllCount')
->withCount(['finalTerm as finalTermPromoted' => function($q) {
$q->where('number', '>', 32);
}])
->withCount('finalTerm as finalTermAllCount')
->with('firstTerm')
->with('secondTerm')
->with('finalTerm')
->get();
return view('admin.showResult.show',compact('students'));
}
@foreach($students as $student)
@if($student->firstTermPromoted == $student->firstTermAllCount
&& $student->secondTermPromoted == $student->secondTermAllCount
&& $student->finalTermPromoted == $student->finalTermAllCount)
{{ "Promoted" }}
@else
{{ "Not Promoted" }}
@endif
@endforeach

Loop-through-loop-through dataframe: How to improve performance on loop that calculates the result based on another loop

I think the issue was by ths following , I need to process a huge dataset of million entries, with the following format: , A data.table approach using non-equi joins: library(data.table)
setDT(visits)[, clicks_30days :=
visits[.(person_id=person_id, start=date, end=date+30L),
on=.(person_id, date>=start, date<=end), sum(clicks), by=.EACHI]$V1
]

vi <- visits
