Answer 1

<?php
$array=array("string",array(1,2,3),true,"php");
foreach($array as $key=>$value)
{
if(is_array($value))
{
foreach($value as $childkey=>$childvalue)
{
echo $key . "." . $childkey . "=>" . $childvalue . "\n";
}
}
elseif(is_bool($value))
{
echo $key . "=>" . ($value ? "true" : "false") . "\n";
}
else
{
echo $key . "=>" . $value . "\n";

}
function convArray($arr)
{
foreach($arr as $k1=>$v1){
if(is_array($v1)){
foreach($v1 as $k2=>$v2){
$res[$k1.'.'.$k2]=$v2;
}
}else{
$res[$k1]=$v1;
}
}
return $res;
}
?>

Try this:

$kt = array();
function showarray($arr,$k) {
global $kt;
foreach($arr as $key => $v) {
$nk = $k == '' ? $key:$k.'.'.$key;
if(is_array($v)) {
showarray($v,$nk);
} else {
$kt[$nk] = $v;
}
}
}
showarray($array,"");
print_r($kt);
