ProgramGuruIn PHP, you can iterate over each element in the set and convert it to a string using type casting or the strval() function.
In this example,
$intSet.$stringSet.$intSet using a foreach loop.$stringSet.<?php
$intSet = new DsSet([1, 2, 3, 4, 5]);
$stringSet = new DsSet();
foreach ($intSet as $num) {
$stringSet->add((string)$num);
}
var_dump($stringSet);
?>object(Ds\Set)#2 (5) {
[0]=>
string(1) "1"
[1]=>
string(1) "2"
[2]=>
string(1) "3"
[3]=>
string(1) "4"
[4]=>
string(1) "5"
}
In this example,
$intSet.$stringSet.$intSet using a foreach loop.strval() function and add it to the $stringSet.<?php
$intSet = new DsSet([1, 2, 3, 4, 5]);
$stringSet = new DsSet();
foreach ($intSet as $num) {
$stringSet->add(strval($num));
}
var_dump($stringSet);
?>object(Ds\Set)#2 (5) {
[0]=>
string(1) "1"
[1]=>
string(1) "2"
[2]=>
string(1) "3"
[3]=>
string(1) "4"
[4]=>
string(1) "5"
}
