{
$sub .= $str[$i];

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

For example: A = 2, B = 4 & C = 2 then output should be uniqueNumber(A, B, C) = 4
if ($A==$B)
{
return $C;
}
if ($A==$C)
{
return $B;
}
return $A;
This should be a simple logic answer and you can either go with direct comparisons but that might be too hectic in case of more than 3 arguments.
You can try this out as well:
$num_arr = [$a,$b,$c];
for($i=0;$i<count($num_arr)-1; $i++)
{
if(!in_array($num_arr[$i],array_merge(array_slice($num_arr,0,$i),array_slice($num_arr,$i+1))))
return $num_arr[$i];
}
Or simply like this:
$num_arr = [$a,$b,$c];
for($i=0;$i<count($num_arr)-1; $i++)
{
$temp = $num_arr;
unset($temp[$i]);
if(!in_array($num_arr[$i],$temp))
return $num_arr[$i];
}
Tried implementing a more generic approach.
Hope it helps.

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;
}
}

Im trying to display 2 or more unique random results from a text file, How do I do that please?
But I need unique results and not 2 or more of the same.
Currently using this code, but it only returns 1 random result:
<?php
$text = file_get_contents('flatFileDB.txt');
$textArray = explode("\n", $text);
$randArrayIndexNum = array_rand($textArray);
$randPhrase = $textArray[$randArrayIndexNum];
?>
<?php echo $randPhrase ?>
I would use something like that
shuffle($textArray);
echo $textArray[0];
echo $textArray[1];
http://php.net/manual/tr/function.shuffle.php
You can give a shot to this also. Code is not tested. I am collecting the used into an array, and check, is that used before.
$text = file_get_contents('flatFileDB.txt');
$textArray = explode("\n", $text);
$used = array();
$countOfRandoms = 2;
$randoms = array();
$i = 1;
do {
if ($countOfRandoms == $i) {
break;
}
$randArrayIndexNum = array_rand($textArray);
if (in_array($randArrayIndexNum, $used)) {
continue;
}
$used[] = $randArrayIndexNum;
$random = $textArray[$randArrayIndexNum];
$i++;
} while (true);
