echo a complex array and indent subarrays - php

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.

Answer 1

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; $i++)
echo " "; // You can change how you indent here
if(!is_array($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);

Answer 2

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);
?>

Answer 3

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; $p++){
echo " ";
}
echo "Array: {" ;
recurseDisplay($item,$padding);
echo " <br /> } <br />";
}
else{
for ($p = 0; $p < $padding; $p++){
echo " ";
}
echo "key :" . $item . "<br />";
}
}
}
recurseDisplay($my_array);

Answer 4

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)

Answer 5

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']);
}
}
