Passing array from PHP to JS iteratively

Question

I'm passing variables from PHP to JS using the following approach:

var dbGen = parseInt("<?php echo $gen; ?>");

However, I'm struggling a lot to do this from an array (pushing each element from a PHP array to a JS array). This is because there I can't seem to place a JS iterator "i" inside the loop, as it recognizes it as php code:

var dbDNA = [];

for (var i = 0; i < 10; i++) {
    dbDNA.push(parseInt("<?php echo $DNA[i]; ?>"));
}

I also tried writing a function (ES6) that would combine everything as a string and try to execute the php code, but that didn't work either:

function pushToArray(arr, ind){
    let str = `<?php echo ${arr}[${ind}]; ?>`;
    dbDNA.push(parseInt(str));
}

for (var i = 0; i < 10; i++) {
    pushToArray("$DNA", i);
}

Any ideas on how I could solve this?

Many thanks!

json_encode() is sufficient...

var somevar = <?php echo json_encode( $array ); ?>;
