I want to echo all the values of the arrays using foreach loop within a function

Question

I was trying to echo all the values of the $sel_arrays using the foreach loop within a function called country(). I was using the loop within the country() function and return the value $sel. But it does output only the single value Bangladesh. I want to get the all values of the $sel_arrays.Though I know that foreach loops iterates all the arrays values, But these codes does not give my expected result. Below my codes...

    <?php 
    function country() {
        $sel_arrays = array('Banglasesh','Pakistan','USA','India','Italy');

        foreach( $sel_arrays as $sel ) {
            return $sel;
        }
    }
    echo country(); // output only Bangladesh. That i ain't wanting.
    ?>

I did not get it how it is happening. Please help to get all the values of the array.

Why you are using foreach loop, if you need to get $sel_arrays.. Just return $sel_arrays variable and remove foreach loop.. — Kamall A Joshi

Your function returns, and then exits the function, in the first iteration. This is how return works. To work around it, you could add all the values to a string, and echo that string instead.

function country() {
    $sel_arrays = array('Banglasesh','Pakistan','USA','India','Italy');

    $result = "";
    foreach( $sel_arrays as $sel ) {
        $result .= $sel." ";
    }
    return $result;
}
echo country(); // outputs everything, separated by a space
