6,023 PointsHow to see the return value of array_push?
This is an example of array_push function from PHP manual:
<?php
$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
print_r($stack);
?>
After array_push, now I know the array $stack has four elements in it, there are "orange", "banana", "apple", "raspberry".
According to the manual, the "returning value" of the array_push function is an integer, which tells the new numbers of element after "being pushed". But how do I see that number? Not by "echo $stack".

230,688 PointsYou could just echo it as you do it:
<?php
$stack = array("orange", "banana");
echo array_push($stack, "apple", "raspberry");
print_r($stack);
?>
You could also save it in a new variable if you might need it later.
