To create a set of size N in PHP, you can use a loop to add elements to an array until it reaches the desired size, then convert the array to a set using the array_flip function.
In this example,
createSetOfSizeN
that takes an integer n
as a parameter. This parameter represents the desired size of the set.array
.for
loop to add integers from 1 to n
to the array.array_flip
function, which swaps the keys with their associated values.createSetOfSizeN
with a specific size (e.g., 5) and store the result in a variable named mySet
.print_r
.<?php
function createSetOfSizeN($n) {
$array = [];
for ($i = 1; $i <= $n; $i++) {
$array[] = $i;
}
return array_flip($array);
}
$mySet = createSetOfSizeN(5);
print_r($mySet);
?>
Array ( [1] => 1 [2] => 2 [3] => 3 [4] => 4 [5] => 5 )
In this example,
createRandomSetOfSizeN
that takes an integer n
as a parameter. This parameter represents the desired size of the set.array
.while
loop to add random numbers to the array until it reaches the desired size.array_flip
function.createRandomSetOfSizeN
with a specific size (e.g., 5) and store the result in a variable named myRandomSet
.print_r
.<?php
function createRandomSetOfSizeN($n) {
$array = [];
while (count($array) < $n) {
$randomNumber = rand(1, 100); // Generate random number between 1 and 100
$array[$randomNumber] = true;
}
return array_flip(array_keys($array));
}
$myRandomSet = createRandomSetOfSizeN(5);
print_r($myRandomSet);
?>
Array ( [14] => 14 [56] => 56 [32] => 32 [78] => 78 [99] => 99 )
In this tutorial, we learned How to create a Set of size N in PHP language with well detailed examples.
