echo a complex array and indent subarrays

Question

I have a complex array, something like that:

Array {
        k1 => text1
        k2 => Array {
                      k3 =>text2
                      k4 => Array {
                                    k5 => text3
                                  }
                      k6 => text4
                    }
      }

And i want to echo the array but to indent every subarray like this:

key: k1 >> value: text1
Array key: k2 >> values:
    key: k3 >> value: text2
    Array key: k4 >> values:
        key: k5 >> value: text3
    key: k6 >> value: text4

Let me know if you need any details.

Indention is implemented differently in various contexts. Can you explain more fully how you intend to present this data? Are you showing it in a web browser, on a console, or somewhere else? — George Cummins, Jul 22 '11 at 15:09

Here's a recursive function that will indent:

(Edited: Indentation wasn't working properly for all subelements, now it does)

function arrayPrettyPrint($arr, $level = 0) {
    foreach($arr as $k => $v) {
        for($i = 0; $i < $level; $i++)
            echo "&nbsp;";   // You can change how you indent here
        if(!is_array($v))
            echo($k . " => " . $v . "<br/>");
        else {
            echo($k . " => <br/>");
            arrayPrettyPrint($v, $level+1);
        }
    }
}

$arr = array(
    1, 2, 3,
array( 4, 5, 
    array( 6, 7, array( 8 )))
);

arrayPrettyPrint($arr);

It's print array like your.

<?php

function print_array($array, $tabs = '') {
    $result = '';
    if (is_array($array)) {
        foreach ($array as $k => $v) {
            if (is_array($v)) {
                $result .= $tabs . 'Array key: '. $k . ' >> values: ' . PHP_EOL . print_array($v, $tabs."\t");
            } else {
                $result .= $tabs . 'key: ' . $k . ' value: ' . $v . PHP_EOL;
            }
        }
    } else {
        $result = $array . PHP_EOL;
    }
    return $result;
}

$array = array(
    'k1' => 'text1',
    'k2' => array(
        'k3' => 'text2',
        'k4' => array(
            'k5' => 'text3'
        ),
        'k6' => 'text4'
    )
);

echo print_array($array);

?>

Try building on this quick function:

function recurseDisplay($my_array,$padding = 2){

   echo "<br />";
   foreach($my_array as $item){
     if (is_array($item)){
       $padding += 10;
       for ($p = 0; $p < $padding; $p++){
         echo "&nbsp;";
       }
       echo "Array: &nbsp; {" ;
       recurseDisplay($item,$padding);
       echo " <br /> } <br />";
     }
     else{
        for ($p = 0; $p < $padding; $p++){
         echo "&nbsp;";
       }
       echo "key :" . $item . "<br />";
     }
   }
 }

 recurseDisplay($my_array);

Would var_dump do the job for you?

 myVar = Array {
        k1 => text1
        k2 => Array {
                      k3 =>text2
                       k4 => Array {
                                    k5 => text3
                                  }
                      k6 => text4
                    }
      }

try it

var_dump(myVar)

It appears that this question was asked before here. This was the solution by KeithGrant

function RecursiveWrite($array) {
    foreach ($array as $vals) {
        echo "\t" . $vals['comment_content'];
        RecursiveWrite($vals['child']);
    }
}

yes but how to make the indent because the array i know how to echo bou without the indent – Sp3ct3R Jul 22 '11 at 14:53
are you talking about using `CSS`? is this a styling question? – Phil Jul 22 '11 at 14:54
i guess it could be done by css too but the ideea was to add 4 &nbsb; when another nested array was found – Sp3ct3R Jul 22 '11 at 14:59
the correct way to acomplish what i want is in the @watcher answer – Sp3ct3R Jul 22 '11 at 15:21
