Use
array_merge
to concatenate two numerically-indexed arrays; not array_push
and not the array union operator: +
.
$first = array('doh', 'ray', 'me');
$second = array('fah', 'soh', 'lah', 'te', 'do');
echo "Union: ", var_export($first + $second, true), "n";
echo "Merge: ", var_export(array_merge($first, $second), true), "n";
// array_push returns int, not an array:
array_push($first, $second);
echo "Push: ", var_export($first, true), "n";
The output:Union: array ( 0 => 'doh', 1 => 'ray', 2 => 'me', 3 => 'te', 4 => 'do', ) Merge: array ( 0 => 'doh', 1 => 'ray', 2 => 'me', 3 => 'fah', 4 => 'soh', 5 => 'lah', 6 => 'te', 7 => 'do', ) Push: array ( 0 => 'doh', 1 => 'ray', 2 => 'me', 3 => array ( 0 => 'fah', 1 => 'soh', 2 => 'lah', 3 => 'te', 4 => 'do', ), )
