Hi,
I wrote a piece of code for doing a recursive printing of all the leaf nodes.
But it is not moving beyond one or two levels.
Here is the code:
$root = array(
"paa" => array (
"adi1" => array (
"cir1" => array (
"aka",
"ra", "vinodh","dkido"
),
"cir2" => array (
"muta",
"la"
),
"cir3" => array (
"ezut",
"telAm"
),
"cir4" => array (
"ati"
)
),
"adi2" => array (
"cir1" => array (
"paka",
"vaV"
),
"cir2" => array (
"mutaR",
"RE"
),
"cir3" => array (
"ula",
"ku"
)
)
)
);
function traverse($ar)
{
foreach($ar as $key=>$value)
{
echo "inside loop of ".$key."<br/>";
if(is_array($value))
{
return traverse($value);
}
else
{
echo $key."==>".$value."<br/>";
}
}
}
traverse($root);
The output I get is:
inside loop of paa
inside loop of adi1
inside loop of cir1
inside loop of 0
0==>aka
inside loop of 1
1==>ra
inside loop of 2
2==>vinodh
inside loop of 3
3==>dkido
It does not seem to visit the other nodes.
Anything I missed here ?
