I need your help to get the position of duplicate or same elements in an array.
For example
$arr =[6,5,3,7,40,45,7,6,3,32,86,40,5,3,7,40];
Result
6 = 0,7
5 = 1,11
3 = 2,8
7 = 3,6,14
40 = 4,11,15
45 =5 and so on.
One simple approach:
<?php
$arr =[6,5,3,7,40,45,7,6,3,32,86,40,5,3,7,40];
$pos = array();
foreach($arr as $k => $v) {
$pos[$v][] = $k;
}
foreach($pos as $k => $v) {
echo $k."=".implode(',', $v)."<br>";
}
?>
Result:
6=0,7
5=1,12
3=2,8,13
7=3,6,14
40=4,11,15
45=5
32=9
86=10

$value = 502;
while($value > $div) {
$value = $value - $div;
echo $div . "<br>";

If i have a loop for example
for ($a=1; $a<6; $a++)
Is it possible to say for the first loop if another variable like $b is the same as one of the other numbers that will come like 2, 3, 4 or 5.
And what if i have a word split, so every letter is a variable like this:
$letter1 = str_split($word)[0];
$letter2 = str_split($word)[1];
$letter3 = str_split($word)[2];
$letter4 = str_split($word)[3];
$letter5 = str_split($word)[4];
How can i check if $a is at 1 in the loop,if it is not letter1 but letter2, 3, 4 or 5?
sure. Just check it against the counter:
for ($a=1; $a<6; $a++){
if ($a===$b){
echo ("b is caught!");
break;
}
}

I am trying to get a number between 1 to 6 with more chances to be close to 1.
i have tried this:
<li>{{Faker\Factory::create()->biasedNumberBetween($min = 10, $max = 20, $function = 'unbiased')}}</li>
What i am trying to do is to generate a number from 1 to 6 rand(1,6); but make the numbers be closer to one as the lower numbers will have more weight than the others.
Something like this ?
<?php
function weightedRand($min, $max, $weightedMax) {
$arr = array();
for($i = 0; $i < 10; $i++) {
$arr[] = rand($min, $weightedMax);
}
$arr[] = rand($min, $max);
return $arr[rand(0,10)];
}
echo weightedRand(1,6, 3);
?>
numbers below 4 will now be more likely than numbers above :)
