How to add a string value into a PHP array

Question

When I add a string value into an array through array_push(), it gives me a numeric value, i.e.,

$array = array("one", "two", "three");
$array2 = array("test", "test2");
foreach ($array as $value) {
    if ($value === 'one') {
        $push = array_push($array2, $value);
    }
}
print_r($push);

Its output is 3. I want $array2 = array("test", "test2", "one")

Answer 1

The array_push is working as it is designed for.

It will add the value and returns the number of elements in that array.

so it is natural if it is returning 3 your array has 2 elements after array push there are now three elements.

You should print_r($array2) your array and look the elements.
