How can I get this format? Result should be dynamic:

1 

a 

b 

0

This is my original array:

$arr = array(0 => 1,

        array(

            0 => 'a',

            1 => 'b'

        ),

        'c' => '0'

    );

I've tried:

$kArr = array();

for($i=0; $i<count($arr); $i++ ){

    $iArr = array();

    echo $arr[$i];

    foreach($arr[$i] as $key => $value){

        if(!is_array($value)) continue;



        foreach($value as $subKey => $subValue){            

            $iArr = $subValue;

        }

    }



    if(count($iArr) > 0 )

        $kArr[$i] = $iArr;

}



echo '<pre>'; print_r($kArr);

Where I am wrong? if there is another method then please let me know.

foreach ($arr as $k => $v) {

        if (is_array($v)) {

            foreach ($v as $k2 => $v2) {

                echo "$v2n";       

            }

        } else {

            echo "$vn";

        }

    }

if you want to do it from scratch you can try something like this.

To achieve your desired result you have to loop through your $arr variable and check if it's an array using is_array function. If it is an array then loop through that array and out put the values.
Try the following code.

$arr = array(0 => 1,

        array(

            0 => 'a',

            1 => 'b'

        ),

        'c' => '0'

    );

foreach($arr as $key => $value)

{

    if(is_array($value))

    {

        foreach($value as $inner_key => $inner_value)

        {

            echo "<br>";

            echo $inner_value;

        }       

    }

    else

    {

            echo "<br>";

            echo $value;        

    }

}

I wrote a function that gets the values of the internal arrays and adds them in the correct order:

function array_values_recursive(array $array)

{

    $values = array_values($array);



    foreach ($values as $key => $value) {

        if (is_array($value)) {

            $innerValues = array_values_recursive($value);



            if ($innerValues) {

                array_splice($values, $key, 1, $innerValues);

            }

        }

    }



    return $values;

}

Example:

$array = array(

    0 => 1,

    array(

        0 => 'a',

        1 => 'b'

    ),

    'c' => '0'

);



$values = array_values_recursive($array);



echo(implode(PHP_EOL, $values));

Will print:

1

a

b

0

function flatten($array) {

    // flattened array

    $flat = ;

    // flattening anonymous function 

    $flatten = function ($array) use (&$flatten, &$flat) {

        // loop over an array

        foreach ($array as $item) {

            // if item is array, use flattening function 

            if (is_array($item)) {

                $flatten($item);

            } else {

                // else push item to flattened array

                $flat = $item;

            }

        }

    };

    // initial call of flattening function

    $flatten($array);



    // return flattened array

    return $flat;

}



var_dump(flatten([

    0 => 1,

    [

        0 => 'a',

        1 => 'b'

    ],

    'c' => '0'

]));

Just use array_walk_recursive.

$r = ;

array_walk_recursive($arr, function ($e) use (&$r) {

    $r = $e;

});
