Converting Python nested loop to PHP nested loop-CodePudding

I have created the following nested for loop in python - the idea is to take a int value for hours e.g 6 and then create an array of values from 1-6

hours = 6
hoursArray = [6]
convertHours = [] #Creating empty list



for i in hoursArray:
    for j in range(i-1): #This will iterate till the value in list - 1
        convertHours.append(j 1) #Appending values in new list
        hoursList = convertHours   hoursArray
    print(hoursList) #adding both the lists

output [1, 2, 3, 4, 5, 6]

Here is my attempt with php - I'm confused about the inner loop and how to do "for j in range(i-1)" in php also in php i should be getting the max value of the array into the range of the outer loop for($i = 0; $i <= $hoursArray-1; $i ) - again i'm not sure how to do this so i put in the int value $hours to test it.

<?php
$hours = 6;
$hoursArray = [$hours];
$convertHours =[];

for($i = 0; $i <= $hours-1; $i  ) {

     for($j = 0; $j <= $i-1; $j  ) {
      $convertHours = [$j 1];
      $hoursList = array_merge($convertHours, $hoursArray);

   }

 }
var_dump($hoursList);
print_r($hoursList);

?>

Output array(2) { [0]=> int(5) [1]=> int(6) } Array ( [0] => 5 [1] => 6 )

Any help appreciated!!

Your problem is in the line of $convertHours = [$j 1];. This way you overwrite the value that was in $convertHours before. You have to write $convertHours[] = $j 1; This way there will be a new value appended to the array. Alternatevly you can also use array_push($convertHours, $j 1)

CodePudding user response：

array_merge merges the 2 arrays based on their key

$convertHours = [$j 1];

Is equivalent to:

$convertHours = [0 => $j 1];

So when you merge them they all have the same key but differents values.

You should do something like that I think:

for($j = 0; $j <= $i-1; $j  ) {
  $hoursArray[] = $j 1; 
}

This append to your array the values $j 1 then ultimately you could use sort to sort your array
