3 dimension Array foreach - php

Question

Im having some problem displaying a multidimensional array...
$copyscape = array (
'query' => 'www.example.html',
'querywords' => 444,
'count' => 230,
'result' => array(
'number' => array(
'index' => 1,
'url' => 'http://www.archives.gov/exhibits/charters/declaration_transcript.html',
'title' => 'Declaration of Independence - Text Transcript',
'minwordsmatched' => 406,
'viewurl' => 'http://view.copyscape.com/compare/w4med9eso0/1'
)
)
);
Basically I want to display everything and also save it in a variable...
echo "<ul>";
foreach($copyscape as $name => $value)
{
echo "<li>" . $name . " : ". $value . "</li>";
}
echo "</ul>";
I tried inserting another set of foreach inside but it gives me an
Invalid argument supplied for foreach()

Answer 1

Try with this code :
$copyscape = array (
'query' => 'www.example.html',
'querywords' => 444,
'count' => 230,
'result' => array(
'number' => array(
'index' => 1,
'url' => 'http://www.archives.gov/exhibits/charters/declaration_transcript.html',
'title' => 'Declaration of Independence - Text Transcript',
'minwordsmatched' => 406,
'viewurl' => 'http://view.copyscape.com/compare/w4med9eso0/1'
)
)
);
function test_print($item, $key)
{
echo "<li>" . $key . " : ". $item . "</li>";
}
echo "<ul>";
array_walk_recursive($copyscape, 'test_print');
echo "</ul>";

Answer 2

use this
foreach ($copyscape as $key=>$value){
echo "<li>" . $key. " : ". $value. "</li>"; // this for main Array
if (is_array ($value))
{
foreach ($value as $childArrayKey => $childArrayValue ){
echo "<li>" . $childArrayKey . " : ". $childArrayValue . "</li>"; // this for childe array
}
}
}
or
foreach ($copyscape as $key=>$value){
echo "<li>" . $key. " : ". $value. "</li>"; // this for main Array
foreach ($value['result']['number'] as $childArrayKey => $childArrayValue ){
echo "<li>" . $childArrayKey . " : ". $childArrayValue . "</li>"; // this for childe array
}
}

Answer 3

In case if you want to have lists inside of lists (nested levels)..
function outputLevel($arr)
{
echo '<ul>';
foreach($arr as $name => $value)
{
echo '<li>';
if (is_array($value))
outputLevel($value);
else
echo $name . ' : ' . $value;
echo '</li>'
}
echo '</ul>';
}
outputLevel($copyscape);

Try following code:
<?php
$copyscape = array (
'query' => 'www.example.html',
'querywords' => 444,
'count' => 230,
'result' => array(
'number' => array(
'index' => 1,
'url' => 'http://www.archives.gov/exhibits/charters/declaration_transcript.html',
'title' => 'Declaration of Independence - Text Transcript',
'minwordsmatched' => 406,
'viewurl' => 'http://view.copyscape.com/compare/w4med9eso0/1'
)
)
);
MultiDimRecuArray($copyscape);
function MultiDimRecuArray($copyscape) {
echo "<ul>";
foreach ($copyscape as $key=>$val) {
if(is_array($val)){
MultiDimRecuArray($val);
}else{
echo "<li>" . $key . " : ". $val . "</li>";
}
}
echo "</ul>";
}

Answer 5

Try something with a recursive function, like this:
function printArray($array)
{
echo "<ul>";
foreach($array as $name=>$value)
{
if(is_array($value))
{
printArray($value);
}
else
{
echo "<li>" . $name . " : ". $value . "</li>";
}
}
echo "</ul>";
}
$copyscape = array (
'query' => 'www.example.html',
'querywords' => 444,
'count' => 230,
'result' => array(
'number' => array(
'index' => 1,
'url' => 'http://www.archives.gov/exhibits/charters/declaration_transcript.html',
'title' => 'Declaration of Independence - Text Transcript',
'minwordsmatched' => 406,
'viewurl' => 'http://view.copyscape.com/compare/w4med9eso0/1'
)
)
);
printArray($copyscape);

Use this
<?php
$copyscape = array (
'query' => 'www.example.html',
'querywords' => 444,
'count' => 230,
'result' => array(
'number' => array(
'index' => 1,
'url' => 'http://www.archives.gov/exhibits/charters/declaration_transcript.html',
'title' => 'Declaration of Independence - Text Transcript',
'minwordsmatched' => 406,
'viewurl' => 'http://view.copyscape.com/compare/w4med9eso0/1'
)
)
);
PrintMultiDimArray($copyscape);
function PrintMultiDimArray($copyscape) {
echo "<ul>";
foreach ($copyscape as $key=>$val) {
if(is_array($val)){
echo "<li>";
PrintMultiDimArray($val);
echo "</li>";
}else{
echo "<li>" . $key . " : ". $val . "</li>";
}
}
echo "</ul>";
}
?>

Answer 7

try this..
echo '<ul>';
displayList($copyscape);
echo '</ul>';
function displayList($arr)
{
foreach($arr as $name => $value) {
if (is_array($value)) {
displayList($value);
}
else {
echo '<li>';
echo $name . ' : ' . $value;
echo '</li>';
}
}
}

Answer 8

Use this:
function print_stuff($arr){
foreach($arr as $key => $val){
if(is_array($val)){
echo "$key: <ul>";
print_stuff($val);
echo "</ul>";
} else {
echo "<li>$key : $val</li>\n";
}
}
}
echo "<ul>";
print_stuff($copyscape);
echo "</ul>";
The code prints a nested list including the key name of the nested lists:
query : www.example.html
querywords : 444
count : 230
result:
number:
index : 1
url : http://www.archives.gov/exhibits/charters/declaration_transcript.html
title : Declaration of Independence - Text Transcript
minwordsmatched : 406
