Display an array in a readable/hierarchical format

Question

Here is the code for pulling the data for my array

Answer 1

For single arrays you can use implode, it has a cleaner result to print.

<?php
$msg = array('msg1','msg2','msg3');
echo implode('<br />',$msg);
echo '<br />----------------------<br/>';

echo nl2br(implode("\n",$msg));
echo '<br />----------------------<br/>';
?>

For multidimensional arrays you need to combine with some sort of loop.

<?php
$msgs[] = $msg;
$msgs[] = $msg;
$msgs[] = $msg;
$msgs[] = $msg;
$msgs[] = $msg;
foreach($msgs as $msg) {
    echo implode('<br />',$msg);
    echo '<br />----------------------<br/>';
}
?>

Answer 2

I have a basic function:

function prettyPrint($a) {
    echo "<pre>";
    print_r($a);
    echo "</pre>";
}

prettyPrint($data);

EDIT: Optimised function

function prettyPrint($a) {
    echo '<pre>'.print_r($a,1).'</pre>';
}

EDIT: Moar Optimised function with custom tag support

function prettyPrint($a, $t='pre') {echo "<$t>".print_r($a,1)."</$t>";}

Answer 3

This may be a simpler solution:

echo implode('<br>', $data[0]);

Answer 4

I use this for getting keys and their values $qw = mysqli_query($connection, $query);

while ( $ou = mysqli_fetch_array($qw) )
{
    foreach ($ou as $key => $value) 
    {
            echo $key." - ".$value."";
    }
    echo "<br/>";
}

Answer 5

I would just use online tools.

• first do print_r(your_array)

• Second copy the result and paste in http://phillihp.com/toolz/php-array-beautifier/

Answer 6

if someone needs to view arrays so cool ;) use this method.. this will print to your browser console

function console($obj)
{
    $js = json_encode($obj);
    print_r('<script>console.log('.$js.')</script>');
}

you can use like this..

console($myObject);

Output will be like this.. so cool eh !!
