Well I have the following array:
$teste = array(1,2,3,4);
When I want to write it on the screen do I do this?
foreach ($teste as $c) {
echo $c;
}
The result is: 1234
I need to write the result 2 times and following the order, like this: 11223344
Does anyone know how to do this using just foreach ?
The code that is inside foreach is large and I do not want to repeat it, I want to find some way to do this in%
I would recommend you refactor your code. If it is reusable, it could very well be defined in a function. In this case, it would suffice to do:
foreach ($teste as $c) {
echo foo($c), foo($c);
}
But if you want to get around this, you can go through the array via a generator:
function doubleForeach($arr) {
foreach($arr as $item) {
yield $item;
yield $item;
}
}
So, you just have to do it:
$teste = array(1,2,3,4);
$iterator = doubleForeach($teste);
foreach ($iterator as $c) {
echo $c;
}
See working at Repl.it
Alternatively, you can control using another repeat structure
foreach ($teste as $c) {
for (int $i=0; $i<2; $i++){
echo $c;
}
}
