PHP-从函数中的循环值返回数组

Question

For example, I have a function like this:

function loopValues()
{
    $a = array('a','b','c');
    foreach($a as $b)
    {
        $c = $b.'e';
        echo $c;
    }
}

How could I return its value aebece in an array like ('ae','be','ce') ?

Answer 1

$a = array('a','b','c');
$b = array_map(function($ele) {
    return $ele .= 'e';
}, $a);

Try

function loopValues()
{
    $a = array('a','b','c');
    $result = array();
    foreach($a as $b){
        $result[] = $b.'e';
    }
    return $result;
}

$r = loopValues();
print_r($r);
