'array_push is replacing the variables instead of adding them to the end

array_push($info["First_Names"], "$fname");
array_push($info["Last_Names"], "$lname");
array_push($info["Gender"], "$gender");

Does anyone see an issue? Array push is just replacing variables instead of adding them. The variables of $fname, $lname, and $gender are defined by the user in a form. I want the variables to simply be added to the end of the array instead of being replaced. Any responses are appreciated.

From the manual:

Note: If you use array_push() to add one element to the array it's better to use $array[] = because in that way there is no overhead of calling a function.

e.g.

<?php

$info["First_Names"][] = $fname;
$info["Last_Names"][] = $lname;
$info["Gender"][] = $gender;

?>

Alternative is use a function.

<?php
function add_in_key_array($array, $key, $value){
 $array[$key][] = $value;
}
?>
