Display an array in a readable/hierarchical format

Question

Here is the code for pulling the data for my array

Answer 1

print_r() is mostly for debugging. If you want to print it in that format, loop through the array, and print the elements out.

foreach($data as $d){
  foreach($d as $v){
    echo $v."\n";
  }
}

Answer 2

echo '<pre>';
foreach($data as $entry){
    foreach($entry as $entry2){
        echo $entry2.'<br />';
    }
}

Answer 3

<?php 
//Make an array readable as string
function array_read($array, $seperator = ', ', $ending = ' and '){
      $opt = count($array);
      return $opt > 1 ? implode($seperator,array_slice($array,0,$opt-1)).$ending.end($array) : $array[0];
}
?>

I use this to show a pretty printed array to my visitors

Answer 4

Very nice way to print formatted array in php, using the var_dump function.

 $a = array(1, 2, array("a", "b", "c"));
 var_dump($a);

Answer 5

Try this:

foreach($data[0] as $child) {
   echo $child . "\n";
}

in place of print_r($data)

Answer 6

I think that var_export(), the forgotten brother of var_dump() has the best output - it's more compact:

echo "<pre>";
var_export($menue);
echo "</pre>";

By the way: it's not allway necessary to use <pre>. var_dump() and var_export() are already formatted when you take a look in the source code of your webpage.
