Dynamic strings in foreach routine

PHP
1

How can I have the following in a foreach routine?

$feed1 = new SimplePie();
$feed1->set_feed_url($url->feed_url);
feed1->init();

$feed2 = new SimplePie();
$feed2->set_feed_url($url->feed_url);
feed2->init();


$count = 0;
foreach ($feedz as $url) {
$feed$i = new SimplePie();
$feed$i->set_feed_url($url->feed_url);
$feed$i->init();
$count++;
}

I know it does not work, the reason I asked your help

tried with $feed[$i] but it gets some strange values from the class. works perfect if it is $feed1, $feed2, … but gives me problems if it is $feed[1], $feed[2]

check out variable variables

$i = 1;
foreach ($feeds as $url) {
    $varName = 'feed'.$i;
    $$varName = new SimplePie();
    $$varName->set_feed_url($url->feed_url);
    $$varName->init();
    $i++;
}

I wouldn’t use so many $$ but just one (okay not literally, but the the idea is the same), like so:

$i = 1;
foreach ($feeds as $url) {
    $varName = ${'feed'.$i};
    $varName = new SimplePie();
    $varName->set_feed_url($url->feed_url);
    $varName->init();
    $i++;
}
